On Board Diagnostics For Your sedan

February 3rd, 2010 by sexton18

Make an appointment with Sexton Tire and Auto Service to have your on board diagnostics analyzed.

Today we’re going to talk about on-board diagnostics and the questions we hear from folks around Montgomery AL who need answers about diagnostic services. They want to know what diagnostics are, what’s involved and what the benefits are. They really want to understand the value of diagnostic scans by a trained technician in Montgomery AL.

These are valid concerns. If you don’t understand something it’s really hard to know its value. Let’s start with some history.

Since 1996, all cars and light trucks in Montgomery AL have been required to use a standardized diagnostic system to help repair technicians determine what’s wrong with your vehicle. The diagnostic system works with the vehicle’s Engine Control Module – the computer that controls many engine functions.

The computer monitors dozens of components and processes. Depending on what the sensors read, the computer will make adjustments to compensate for conditions and minor problems. When there is a condition that it can’t adjust for, the computer will turn on the check engine light.

It is also called the ’service engine soon’ light on some vehicles. The warning light signals you to get into your Montgomery AL service center so that the trouble code can be read and the problem can be fixed. Your service center will have a scan tool and powerful software that will help the technician diagnose the problem.

If you’ve searched for check engine light on the internet, you may have seen that you can buy an inexpensive scanner or go to an auto parts store to have the trouble code read to tell you exactly what’s wrong.

That’s a common myth. The code itself doesn’t tell you what’s broken. It starts you looking in the right place. It tells you what engine parameter is out of range – but it won’t tell you what’s wrong or how to fix it.

Let’s say you think your daughter has a fever. You take her temperature and it reads one 102 degrees. You’ve confirmed a fever, but you don’t know what’s causing it. Is it a 24 hour flu, an infection, appendicitis or leukemia? A fever is a symptom of all of these medical problems, but it takes a skilled physician’s examination and additional diagnostic tests to find out what is actually causing the fever.

An example of a trouble code could be: P0133, which reads ‘Bank 1 sensor 1 circuit slow response’. This means that the front oxygen sensor has a slow response time to changes in the air-fuel mix. If that’s all you knew about cars, you would think your oxygen sensor was broken and would replace it. Now, it could be the oxygen sensor – but it could also be a bad or contaminated airflow sensor, exhaust leak, electrical problem, an intake manifold leak or any of a number of other things.

You can imagine a lot of oxygen sensors have been replaced because of that code. So the on-board diagnostics point the way to where the trouble lies, but it takes some skill and high-tech equipment to actually pinpoint the problem. The cheap scan tools that a consumer can buy do not have the ability to retrieve some of the operating history that’s stored in the engine control computer. That history’s very helpful in diagnosing the problem. Service centers like Sexton Tire and Auto Service invest a lot of money in high-end diagnostic tools to help solve the mystery and get you back on the road as soon as possible without replacing a lot of parts that don’t need replacing.

So, on-board diagnostics provide a powerful starting place for a highly-trained, well-equipped technician to get to the bottom of your problem. When your check engine light comes on, get it checked at Sexton Tire and Auto Service. If the light burns steady – don’t panic. Get in to Sexton Tire and Auto Service soon to have the engine scanned. A flashing check engine light means that there is a severe engine problem. Get in as soon as you can – waiting too long can lead to very expensive damage.

And try to not drive at high speed or tow or haul heavy loads with a flashing check engine light.

Montgomery Drivers Severe Service Maintenance Schedules

January 27th, 2010 by sexton18

Your vehicle manufacturer publishes two auto maintenance schedules. The regular schedule and the severe service schedule. It’d be wrong for us to tell you that everyone in Pike Road always needs to follow the severe service schedule – but its wishful thinking to say that the regular schedule is always good enough for your sedan.

Contact Sexton Tire and Auto Service to learn more about Severe Service Requirements for your sedan
You can find us at:
2718 Zelda Road
Montgomery, AL 36106
Or call us at 334-272-2555

At Sexton Tire and Auto Service we’ll give you the definitions and explain the issues, and you can be the judge. Most manufactures list the following as severe conditions:

  • Most of your trips are less than four miles.
  • Most of your trips are less than 10 miles and outside temperatures are below freezing.
  • The engine is at low speed most of the time – not on the highway.
  • You operate your vehicle in dusty areas.
  • You regularly tow a trailer or carry heavy loads.
  • Driving in very hot or very cold weather.

So think about your typical week. Do you live a block from a AL freeway on-ramp and enjoy a non-stop commute to work in Ramer or Coosada? Or are you like the rest of us where 90% of our trips are on the severe service list?

The answer may be different at different times of the year and for the different drivers in your family. Think of the two service schedules as bookends. Let’s suppose your owner’s manual says the severe service oil change recommendation is 3,000 miles and the standard recommendation is 5,000 miles. You know that you need to change the oil somewhere between 3,000 and 5,000 miles. Look at your driving patterns and Montgomery road conditions and honestly evaluate which end of the spectrum you’re closer to.

If you have a job in a neighboring town such as Wetumpka or Ramer and most of your commute is freeway miles, you may choose the regular service schedule for your car. On the other hand, if you live within a few miles of work and only get on the highway a handful of times every month, something closer to the severe service schedule is more appropriate.

Now why is this so important? Moisture builds up in the engine oil from normal condensation. Short trips around Pike Road or driving when it’s really cold means that the engine doesn’t heat up enough for the moisture to evaporate. The water in the oil leads to oil sludge that gums up your engine and doesn’t let the oil protect it as well. That’s why you need to change your oil more frequently – to get the sludge out before it causes problems.

Towing, heavy loads and very hot AL summer weather means that your engine and transmission will operate at higher temperatures and with more stress. The fluids will break down more quickly. Additives that clean and prevent corrosion will be depleted sooner. Dusty conditions, which may extend also to areas with high air pollution, mean that fluids will get dirty faster and that filters will plug up and won’t work right.

All of these things can lead to premature wear and repairs down the road. They’ll also hurt your fuel economy. If you want some personalized advice, talk with your understanding Sexton Tire and Auto Service service advisor. We can help you restore your vehicle to good working order and help you know the best schedule to follow. If you’re not sure, err on the side of protection.

Diesel Maintenance For AL

January 19th, 2010 by sexton18

At Sexton Tire and Auto Service we hear from a lot of people who are excited about the new diesel engines that will soon be available in passenger cars and SUV’s. But our AL friends are often curious about the preventive maintenance requirements. People may not know that diesel engines have long been used extensively in Europe and Asia. In fact, in some markets, there’re nearly as many diesel powered passenger cars as there are gasoline.

Here’s who’s announced or is expected to announce new diesels for North America: BMW, Mercedes, Audi, Volkswagen, Nissan, Honda, Toyota, Hyundai and Subaru. Of course, the US auto makers will be expanding their diesel offerings as well. Diesels will become a very big deal here in AL.

You may ask, why has it taken so long getting to AL and North America? There are a bunch of reasons like fuel tax policies and such, but the biggest hurtle was that AL diesel fuel had a high sulfur content – too high for the latest generation of highly refined diesel engines. Recent government mandates to remove sulfur now opens up AL to the engines the rest of the world’s been enjoying for a long time.

Why are diesels so popular worldwide? Well, for starters, diesels get up to 30% better fuel economy than gas engines. And they last a lot longer. And modern diesel engines are refined, quiet and powerful – and there’s none of that black smoke we used to see.

Some people may think that diesels create more pollution. But, you need to rethink diesels. Environmental pollution standards for diesel cars and light trucks are scheduled to be as strict as they are for gasoline vehicles. A modern diesel engine is as clean as a gas engine.

You may also have heard a lot in the news about bio-diesel. The exciting thing about diesels is that they’re not limited to fossil fuels. They can run on fuel made from vegetable oil. There are refineries that make diesel fuel from cellulosic waste like woodchips from lumber mills. There’s even this cool new process where a special strain of algae is used to convert carbon dioxide, water and sunshine into bio-diesel. That’s still a ways off, but you can see that diesel can become a sustainable source of fuel.

And, there are not a lot of trade off’s with diesel in terms of performance. A modern passenger car diesel is very smooth, quiet and quick. Most folks wouldn’t notice any difference. For those who tow trailers and haul heavy loads, diesels will be an improvement.

Now diesel engines are heavy duty, so they cost more than gas engines. But they get better fuel economy – so the break-even point is largely dependent on the difference between AL gas and diesel prices at the pump and how many miles you drive. And diesels have a higher resale value.

Now, let’s get back to diesel maintenance. You have to keep in mind that most of the new diesels are just coming in, or will be over the next couple of years, so we don’t have the maintenance schedules to make direct comparisons yet.

But going off what we already have in AL, we can expect fluid drain intervals to be similar to gasoline engines. Diesels do require very clean fuel, air and oil, so their filters are much higher capacity than gasoline filters and cost more. The engine air filter needs to be changed more frequently as well.

Repair costs are similar. As with gasoline engines, proper maintenance is the key to long engine life and to avoiding repairs. So pretty much what we have come to expect with gas vehicles; coolant system service, transmission service, power brakes, power steering, differential, filters, fuel system, and so on. And the payoff for you, if you’re the kind that likes to keep your vehicles for a long time, is that a properly maintained diesel engine can last for hundreds of thousands of miles.

Keeping Your ‘Old Faithful’ Auto Running

January 15th, 2010 by sexton18

At Sexton Tire and Auto Service we’ve had a lot of people asking how they can make their vehicles last longer. These questions are actually a reflection of a trend that’s been building for several years. The median age of personal vehicles is now over nine years. And 33 percent of all vehicles on the road have over 75,000 miles on them. It looks like it’s going to keep heading in that direction for a while. With high fuel prices a lot of folks are putting off buying a new car. Thanks to AutoNetTV, we can provide you with a video answer to this question.

So let’s say you’re one of the average people in the Pike Road area; you’ve got a nine year old car with 80,000 miles on the odometer. What can you to do make it last another year or two?

Let’s start with the premise that there’s no reason that a modern car can’t run for 200,000 miles with proper care. The engineering and manufacturing quality is there.

Of course, some parts will wear out along the way, but there’s no reason for a catastrophic meltdown if you stay on top of your recommended maintenance. The maintenance schedule in some owner’s manuals runs out at 60,000 miles or so: how do we know what to do when we’re way past that?

It is a challenge, for example: If a service is recommended every 15,000 miles for the first 60,000 miles you can just keep getting it done at least every 15,000 miles after you hit 60,000 miles. But, it gets more complicated because older engines lose some efficiency, are dirtier inside and are just more stressed. That means it’s very important to not miss any scheduled services. Skipping just one oil change, for example, leaves an opportunity for harmful sludge to build up.

So all the usual things like oil changes, transmission service, coolant service, brakes, power steering, fuel system cleaning – all that stuff need to be maintained. People responsible for fleet vehicles around Pike Road are positively religious about scheduled maintenance. They know that money spent on maintenance saves them three ways:

  1. it saves fuel;
  2. it prevents costly repairs, an;
  3. they can postpone purchasing new vehicles.

Having the oil changed may be the most important thing. A full service oil change means that all of your other fluids get topped off so they are never low enough to cause damage. It also gives your technician a chance to spot problems in the early stages so that you can fix them before they get expensive. And it gives you a touch point with a professional along the way to remind you of things that aren’t scheduled as often – things like differential service and timing belt replacement.

If you live in the Pike Road area and have an older vehicle, you may need to follow the severe service maintenance schedule. Check your owner’s manual and talk with your service advisor at Sexton Tire and Auto Service. Conditions inside an older engine, transmission and cooling system can arguably be considered severe – so shorter intervals could well be called for.

And, we would strongly encourage you to consider using high mileage formulation fluids. They’re fluids like engine oil, transmission fluid and coolant that are formulated for older engines. They have special additives to clean deposits, and to condition and restore seals and gaskets that dry out with age. Some people start using higher mileage formulations at around 50,000 miles as a preventive measure.

Of course you also want to still look marvelous in your older car. Salt and road grime wreak havoc on your paint job and can lead to body rust – so regular washing is very important. Also, a good quality waxing is recommended at least twice a year.

What To Do In Case Of An Accident in Pike Road

January 5th, 2010 by sexton18

Screeching tires, crunching metal – it’s an accident! If you’ve ever been in a car accident in Pike Road, even a minor one, you know how upsetting it can be. It’s hard to think straight and know what to do.

Let’s review what you should do in case of an accident:

When an accident occurs, you should always stop. Leaving the scene of an accident in Montgomery is considered a crime – even if it’s not your fault. And hit and run penalties are fairly severe, possibly resulting in steep fines, loss of your AL driver’s license or even jail time.

Your jurisdiction may require that you try to help someone who is injured by calling for help or performing first aid if you are able. Warn other Ramer and Coosada motorists by putting out flares, using your flashers or lifting your hood. Call Pike Road emergency services as soon as possible. Tell the operator if medical or fire help is needed.

Always file a Montgomery police report. It’s tempting to skip this if everything seems to be ok. But without a police report, the other guy can say whatever he wants about the accident later, and you’ll not have an objective report to help defend yourself. Discuss the accident only with the police. Emotions are strong after an accident and we naturally want to talk about it – don’t. Never admit fault or guilt to anyone including the police officer. Sometimes we may feel at fault, but in the eyes of the law, the other guy is responsible.

Truthfully give the officer the facts: such as “I was going thirty miles an hour” not “I wasn’t speeding”. Remember, anything you say to the officer or anyone else can be used against you.

Also get the officer’s name and ID number and ask where you can get a copy of the accident report.

Get the facts on the driver and owner of the other vehicle:

  • Name
  • Address
  • Phone number
  • Date of birth
  • Driver’s license number and expiration
  • Insurance information

Also take down a description of the other Montgomery vehicle, license plate and vehicle identification number. Most AL auto insurance companies don’t record license plate numbers, so the VIN number is the best way to track the vehicle.

Ask witnesses, including passengers, to wait for the police. If they can’t wait, ask for contact information and request that they write a brief description of what they saw. If someone refuses to leave their name, write down their license plate number so the police can track them down later if necessary. Always call your insurance agent or your insurance company. Call or see a physician if you think you may have been injured. For vehicle repairs, call Sexton Tire and Auto Service at 334-272-2555

Fuel System Cleaning to Improve Performance in Montgomery, AL

December 31st, 2009 by sexton18

All modern vehicles come with fuel injection systems, so it’s a topic we all need to know something about. All new cars and trucks sold in Montgomery, AL over the last 30 years or so have come with fuel injection systems.

The fuel injector is a valve that delivers the gas or diesel fuel to the right place, in the right amount, at the right time; to be mixed with air and burned in the engine.

So how many fuel injectors does your car have? There’s one for each cylinder. So four, six or eight for most folks in Montgomery, AL. Some vehicles have 10 or 12 cylinders. The engine control computer makes adjustments to the fuel injector as it monitors the engine and other sensors. Fuel injectors are a pretty sophisticated part.

Sexton Tire and Auto Service can help you with a fuel injector cleaning service. What’s the benefit? In order to work right, the fuel injectors have to deliver the fuel at a precise pressure at a very precise time. The fuel needs to be sprayed in a particular pattern as determined by the engine design.

Over time, varnish can start to build up in the fuel injectors, effecting the pressure, pattern and timing of the fuel charge. The result is that the fuel doesn’t get burned as efficiently as it could. That robs performance and wastes fuel.

What about dirty fuel – how does that affect the fuel injectors? The fuel injectors are the last stop in the fuel system. It starts at the fuel tank. Frankly, the best way to keep your fuel injectors working well is to use high quality fuel. Its real tempting to shop for bargains with fuel prices as high as they are, but major brands in the Montgomery, AL area have better detergents and additives and deliver consistent quality.

What about a good fuel filter? The fuel filter is the next device in the fuel system. Its job is to filter out the dirt and rust that collect in the fuel tank. If it’s clogged up, the dirt will bypass the filter and head upstream to the fuel injectors.

It’s important to replace the fuel filter when your manufacturer recommends it. That’s part of a comprehensive fuel system cleaning.

There are different kinds of fuel injection systems. Port fuel injection systems, the kind most gasoline engines have, operate at 60 pounds per square inch. The injectors for the new gas direct injection engines we’re starting to see require 10 to 30 times as much pressure. And some diesel engines for passenger vehicles have injectors that operate at 30,000 pounds or more per square inch. There’s no room for dirt and gum in a precision part like that.

There are a lot of good products available in Montgomery, AL that can clean fuel injectors. They’re best used to prevent fouling in the fuel injectors. Many can’t clean a seriously gummed up injector – that requires a professional deep cleaning. But putting the cleaner in the fuel tank after you’ve had Sexton Tire and Auto Service take a look at your fuel system will help keep it clean. Be sure to read the label for directions.

Give us a call if you think your sedan may be ready for a fuel injector cleaning.

Timing Belt Replacement in Montgomery

December 22nd, 2009 by sexton18

Today we want to talk about timing belts. They’re something that many Montgomery drivers don’t know much about and yet your vehicle won’t run if it’s broken – and it could cause many thousands of dollars damage if it does break. A broken timing belt is usually a tale of woe. Even though timing belt replacement is scheduled in the owner’s manual, it’s not the kind of thing that most Pike Road car owners remember because it’s not well understood.

Let’s review what a timing belt does. As you know, the engine’s power is generated in the cylinders. A piston rides up and down in the cylinder. During the first down stroke, an intake valve at the top of the cylinder opens and air and fuel is drawn into the cylinder. Then the piston returns to the top, compressing the fuel and air mix. At the top, the spark plug fires, igniting the fuel pushing the piston down in the power stroke. As the piston once again returns up in the final stroke of the cycle, an exhaust valve opens at the top of the cylinder and the exhaust is pushed out. The timing belt is what coordinates the opening and closing of the intake and exhaust valves. It’s called a timing belt because the valves have to open and close at just the right time.

Now, not all Wetumpka and Ramer vehicles have timing belts. Some have timing chains. Like the name implies, they use a chain rather than a belt to perform the function. It used to be that most engines used timing chains, which are extremely durable. Manufacturers started using belts rather than chains to save money in the manufacturing process. So now we’re left with a component that can break. They sort of shifted the problem to us. There are two broad categories of engine design: interference and non-interference. If the timing belt on a non-interference engine breaks, the engine simply stops running. That could be very dangerous depending on where you are at the time, but it causes no internal engine damage.

Interference engines, on the other hand, will get real messed up when the timing belt breaks, because the valves will actually fall down into the path of the pistons. Things get chewed up when that happens and it’ll cost thousands to repair the engine.

So, what are the warning signs? Unfortunately, there really aren’t any. There aren’t tell-tale sounds. In some vehicles, a technician from Sexton Tire and Auto Service may be able to see part of the belt for a visual inspection, but many have a cover that’s in the way. The reality is that if the belt slips even one notch, it might as well be broken for all the damage it’ll cause. There’s no middle ground.

So how can we avoid these problems? Simply replace the timing belt when your owner’s manual calls for it. It can be 60,000 miles; it might be 90,000 or 100,000 miles. The point is, if you have 60,000 or more miles, ask your Sexton Tire and Auto Service service advisor right away if your manufacturer requires a timing belt replacement.

Contact Sexton Tire and Auto Service to learn more about your car’s Timing Belt
You can find us at:
2718 Zelda Road
Montgomery, AL 36106
Or call us at 334-272-2555

Sometimes you can go quite a while without a failure, but we’ve seen them happen within a couple of oil changes of being due. It’s not worth the risk.

What does it cost to replace a timing belt in Ramer or Coosada? Well, that really depends on what kind of car you have. I can tell you that it’s usually not very easy to get to the timing belt – you often have to remove some accessories to get at it. It isn’t a cheap procedure, but it’s a fraction of what it could cost to repair the damage caused by a failure.

At Sexton Tire and Auto Service we’re all about trying to prevent costly repairs, keeping you and your passengers safe and increasing your driving enjoyment. Thanks to AutoNetTV for their great auto video tips.

Recommended Service Intervals

December 16th, 2009 by sexton18

Everyone in Montgomery knows we’re supposed to go to the dentist twice a year. We get our teeth cleaned and have a thorough dental inspection. Once a year, we get x-rays to look for problems that can’t be seen with the naked eye. When the dentist is done, he tells us what he’s found – “Everything’s fine, see you in six months.” Or “You’ve got a small cavity starting, let’s schedule an appointment to take care of it.” By the time you leave, you have a plan for addressing any necessary repairs.

This system works so much better than waiting for a painful problem before going into the dentist. Small problems are fixed before they turn into big problems. And you avoid those huge bills.

If we buy into this way of handling our dental care, why do we resist so much when facing the same system for our car care?

Following the manufacturer’s recommended intervals can be confusing. First there are recommendations for so many things: oil changes, transmission, coolant, air conditioning, power steering, brakes, fuel system, filters, belts, hoses, alignment, rotation, balancing …you get the point.

Every item has a recommended interval and it’s hard to keep it all straight – even if you’re part of the one percent of the population that reads your owners’ manual.

And if you have more than one sedan, the complexity is multiplied. You’d need a computer to keep track of everything. We’ll, that’s how Sexton Tire and Auto Service does it. We subscribe to automotive databases that have your vehicle’s recommended intervals. You may have wondered how we know what else to recommend when you bring your car in for an oil change at our Montgomery location – it’s all in the computer.

Well, it’s not all in the computer. There are other variables that can’t be accounted for in the schedule. Things like the weather conditions, altitude, and driving conditions in the Montgomery area to be taken into account. Talk about these things with your Montgomery service advisor at Sexton Tire and Auto Service and you may decide that the severe service schedule in your owner’s manual is more appropriate.

Since anything that’s not highway driving in moderate weather is considered severe, most of us in Montgomery do at least some of that and it should be taken into consideration.

Let’s take your basic oil change as an example – what issues are involved? The oil you put in your car is a blend of base oil and special additives. There are detergents to clean the inside of your engine and corrosion inhibitors. A good quality motor oil will not only lubricate your engine, it will help it stay clean inside and run cooler.

Now, these additives deplete with use and time. That’s why most maintenance recommendations include both a time and mileage element – like three months or 3,000 miles, whichever comes first.

It’s easy to think, “Gee, I’ve only driven 2,000 miles in the last three months. I can wait on that oil change.” But you need to remember that the inside of your engine is a harsh environment. The oil is contaminated with combustion by-products that start degrading its effectiveness even when it’s just sitting there.

A lot of people in Montgomery don’t realize the harm that can be done by just skipping a single oil change. There are a lot of metal parts moving around in your engine. Small bits of metal wear off and are floating around in your oil. They can be carried to more delicate areas of the engine where they cause damage. Your oil filter is designed to trap metal particles and other dirt, but if it’s clogged up because you haven’t changed it, it can’t trap any more.

Oil sludge is another problem. Sludge is oil that has turned to a gunky jelly – think Vaseline. Obviously, sludge doesn’t lubricate. It can also clog small oil passages so that all the parts don’t get properly protected by the oil. That’ll lead to premature wear.

If you’ve missed some oil changes, don’t despair. Just talk with your Sexton Tire and Auto Service service advisor. Fess up – you’ll feel better. And he can help you get back on track. Following recommended intervals is the key to keeping your car on the road and avoiding major repairs.

Keeping Your Car Young in Montgomery

December 10th, 2009 by sexton18

We live in such a disposable society here in Montgomery. It’s amazing all the stuff we throw away.

New stuff comes out so fast, we just toss the old and move on. It seems like when we were kids, our parents were real sticklers about taking care of our stuff. You know, hang up your clothes, polish your shoes, put away your toys. If something got lost or ruined by neglect, tough – we had to do without.

We couldn’t afford new cars very often, so we tried to make them last as long as we could. It’s a good thing that cars are more reliable these days.

They just don’t break down as often. And the good news for us penny pinchers is that a modern car can easily go 200,000 miles with proper care. The engineering’s there and so is the manufacturing quality. The missing ingredient is us making sure we follow the manufacturer’s recommended maintenance schedules.

Is it really that bad to get off schedule? Well, it all adds up. Every time you go a couple thousand extra miles between oil changes, you’ve created an opportunity for sludge to form and clog passages. Then some parts don’t get oiled and they start to wear out faster.

Skip a cooling system service, and the corrosion inhibitors become depleted, and the radiator starts being damaged – one step closer to a failure. The same thing is true for transmission service, power brakes, fuel system cleaning – really everything on your schedule.

It’s also even more important for older vehicles. Those engines and other systems have had more time to get dirty, so they’re a bit more stressed anyway. But it’s never too late to get back on track with your maintenance and to hold off further damage.

It’s just another example of our parents being right. (Surprising how often that happens.) And it really does start with the oil change, just like Dad said. When you get a full service oil change they top off all your fluids and check for other items that are on your maintenance schedule. That’s like your safety net – go in for oil changes on time, and let your service advisor at Sexton Tire and Auto Service help you keep track of the rest.

Of course, some things are going to wear out along the way, stuff like alternators, water pumps and such. But that stuff is cheaper than a new car payment. And taking care of problems early means they have less time to cause other problems. It’s like having high cholesterol – you don’t want to wait for a heart attack before you address it.

Nitrogen Fill For Tires in Montgomery AL

December 4th, 2009 by sexton18

So, everyone in the Montgomery AL area knows how great helium is – you know, party balloons, squeaky voices. But a lot of people around Montgomery still haven’t heard about the benefits of nitrogen in your tires, and how it can help your tires. Here’s some great advice from AutoNetTV, brought to you by Sexton Tire and Auto Service.

Nitrogen has actually been around for a long time in the Montgomery AL commercial sector, but it’s just starting to catch on for private vehicles in the 36106 zip code area.

Why nitrogen in your tires? Air is air, right? Actually, it turns out there is a difference.

Contact Sexton Tire and Auto Service to learn more about nitrogen in your tires
You can find us at:
2718 Zelda Road
Montgomery, AL 36106
Or call us at 334-272-2555

The heart of the matter is maintaining proper tire inflation. When your tires are properly inflated, they last longer, handle better and more safely, and save you money at the gas pump.

The problem is that tires filled in Montgomery with regular air can lose a pound and a half of air pressure every month. This just happens as the oxygen in the tire seeps out. So if you don’t check your pressure for a month or two, well, you can be significantly low – low enough to actually affect your handling, shorten tire life and waste money at the fuel pump.

How does nitrogen help? Regular air contains about 78% nitrogen. Nitrogen is the largest molecule in air. It’s dry and non-flammable. Air also contains 21% oxygen, which is smaller and seeps out of the tire three to four times faster than nitrogen.

So, a tire filled with nitrogen at Sexton Tire and Auto Service will take about six months to lose as much pressure as regular air does in just one month. So it’s more forgiving for those who don’t check their pressure every week.

Also, when oxygen is at higher temperatures – like those inside your tire when you’ve been driving for awhile – it oxidizes the inside of your tire. Getting the oxygen out of your tire means that it’ll last longer.

Who’s using nitrogen? Well, let’s start with NASCAR and Indy. These racers like nitrogen’s ability to maintain consistent tire pressure and reduce tire temperatures under very demanding conditions. The US government requires all commercial aircraft to have nitrogen in their tires. NASA and the US Military use nitrogen. The mining industry has been filling those “humongous” tires with nitrogen for years. And semi trucks and trailers are starting to use nitrogen extensively.

You may have heard some detractors of nitrogen. But the studies and white papers from tire and vehicle manufacturers demonstrate that the technology really works.

In fact, a prominent consumer research group did a study where they filled some tires with air and some with nitrogen and stacked them outside for a year. They observed that the nitrogen filled tires did hold their pressure better, but they couldn’t see the economic benefit. But that particular test has very little to do with the real world. Most tires are actually holding up cars and they also get driven around and do a lot of work. So if nitrogen helps them last longer, saves gas and gives safer handling, it’s worth considering.
