Maintaining Your Older Car In Chicago IL

February 4th, 2010 by saavedra9

The government mandates a lot of equipment on cars in Chicago IL: emission devices and control computers, safety equipment like airbags and crash worthiness requirements. All of this is great for the Chicago IL motoring public, but it does add quite a bit to the price of a new car.

Because new cars are more expensive, people in the Forest Park area are driving their old cars longer. The average car is now over nine years old. Two thirds of vehicles on the road in Forest Park have more than 75,000 miles. As cars age, their performance drops, they have difficulty idling for long periods and are more sensitive to weather extremes. Fortunately today’s cars are up to the challenge – but they need a little help to keep on goin’.

Give Jaime Auto Service a call to schedule your next maintenance.

Some owner’s manuals don’t specify service requirements at higher mileage. That doesn’t mean it doesn’t have to be done. In fact, it’s more important than ever to stay on top of routine maintenance for cars with more than 75,000 miles.

First, just extend regular service intervals out: for instance a service that’s recommended every 15,000 miles should be performed at 15,000, 30,000, 45,000 and 60,000 miles, and so on. Because of the additional stress older engines experience, the severe service maintenance schedule is more appropriate than the regular schedule – ask your service advisor. Watch for leaks – seals and gaskets dry out over time and don’t hold the fluids as well as they used to.

It’s also time to make sure you have a good Chicago IL technician. There are some services and replacements that are scheduled after you put on some clicks, like timing belts, valve train adjustments, suspension, anti-lock brake service, air bags, etc. And unexpected repairs down the road are just par for the course. Check for unusual sounds, smells or the way your car feels. These could be hints that trouble’s brewing. Better to catch it early before it turns into a costly repair.

And a regular wash and wax will help maintain your car’s appearance. One of the things you can do to really help your high mileage vehicle is to begin using high mileage formulation fluids. There are special engine oils, coolants, and transmission and power steering fluids that are formulated for cars that have a few clicks on the old odometer.

High mileage oil is designed to condition seals and gaskets, reduce wear and avoid premature burn off. Older engines are dirtier inside – and dirty engines contaminate their oil faster. High mileage oil has special additives that clean the engine, removing sludge deposits over time. The result is less stress on the engine, better fuel economy and excellent wear protection.

Studies have even shown that using high mileage fluids early will actually prevent some of the problems of high mileage vehicles. So once you hit around 50,000 miles, consider stepping up to high mileage formulations. High mileage fluids cost a bit more than standard fluids because of the additional additives, but they can be worth their weight in gold in terms of preventing repair costs down the road. It does cost more to properly maintain a higher mileage vehicle – but it’s way cheaper than a new car payment!

Questions To Ask Your Chicago Service Advisor

January 28th, 2010 by saavedra9

We find that a lot of Chicago service and repair at Jaime Auto Service are a little tentative when they talk with their automotive advisors. They want to ask questions, but don’t want to be embarrassed or to seem pushy. Cars are very complicated and there’s more to know about them than most of us have the time to learn. Maybe it’s because cars have become so much more reliable that the average person just doesn’t need to know as much to keep their vehicle on the road.

You know, your local hospital has a Patient’s Bill of Rights that they post throughout the hospital. We think our Chicago automotive service customers also have a right to ask any question they need to understand what is wrong with their car and what it will take to fix it. They need to feel free to ask the cost and benefits of recommended services. And they certainly have a right to understand the financial end of the transaction.

It’s all about the communication. It’s a little harder when you’re trying to find the right service center in Chicago. But once you’ve developed a relationship, the communication should come easier.

What are some of the barriers to communication? Well, let’s go back to the medical example. When your doctor’s explaining something to you, it’s something that she understands very well and is very familiar with. So she may use jargon you don’t understand or that you don’t have the education and training that’s foundational to understanding what she’s trying to explain.

So you fall behind and get frustrated.

It can be the same with your Chicago automotive service advisors. Most of them are very busy trying to service and fix cars to get their customers back on the road. So, just ask when you feel you need more information.

Financial related issues seem to be most frustrating to customers. If you’re not sure, ask what the payment policies are. For example, there’s a big difference between giving your car a quick once over and doing a thorough inspection. Diagnosing a problem may take quite a while. Make sure you know what’s done as a courtesy and what has a fee. Remember, you still have to pay for the office visit even if the doctor says you only have a cold.

Communication is a two way street. If you have some real budget concerns, ask your Chicago service advisor what he can do. He can give you priorities and options. He can tell you what needs to be taken care of right away for safety or financial reasons. Then you can work out a plan for when to get the rest done. He can also help you with options on the parts. The preference is to always use a high-quality part with a reputation for reliability. But if money is real tight, he might be able to find a rebuilt part or a used part. He should tell you the difference in the guarantee for the part so you can make a good decision.

Ask about warranties for parts and labor. Be sure to get all the paperwork you need to make a possible claim in the future. Your service center and its technicians stand behind their work and want you to understand precisely what that means.

Be sure to ask for and keep a detailed explanation of all the work that’s done on your vehicle. These records will help you keep track of service, warranties and document the good care your vehicle has received when the time comes to sell it.

Nitrogen Fill For Tires in Chicago IL

January 22nd, 2010 by saavedra9

So, everyone in the Chicago IL area knows how great helium is – you know, party balloons, squeaky voices. But a lot of people around Chicago 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 Jaime Auto Service.

Nitrogen has actually been around for a long time in the Chicago IL commercial sector, but it’s just starting to catch on for private vehicles in the 60638 zip code area.

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

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 Chicago 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 Jaime 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.

Keeping Your ‘Old Faithful’ Auto Running

January 13th, 2010 by saavedra9

At Jaime 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 Forest Park 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 Forest Park 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 Forest Park 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 Jaime 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.

Chicago Drivers Severe Service Maintenance Schedules

January 6th, 2010 by saavedra9

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 Forest Park always needs to follow the severe service schedule – but its wishful thinking to say that the regular schedule is always good enough for your mini-van.

Contact Jaime Auto Service to learn more about Severe Service Requirements for your mini-van
You can find us at:
6010 S Archer Ave
Chicago, IL 60638
Or call us at 773-582-5524

At Jaime 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 IL freeway on-ramp and enjoy a non-stop commute to work in Stone Park or Maywood? 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 Chicago 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 Westchester or Stone Park 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 Forest Park 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 IL 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 caring Jaime 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.

Keeping Your Car Young in Chicago

December 29th, 2009 by saavedra9

We live in such a disposable society here in Chicago. 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 Jaime 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.

Timing Belt Replacement in Chicago

December 22nd, 2009 by saavedra9

Today we want to talk about timing belts. They’re something that many Chicago 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 Forest Park 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 Westchester and Stone Park 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 Jaime 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 Jaime Auto Service service advisor right away if your manufacturer requires a timing belt replacement.

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 Stone Park or Maywood? 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 Jaime 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.

Fuel System Cleaning to Improve Performance in Chicago, IL

December 15th, 2009 by saavedra9

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 Chicago, IL 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 Chicago, IL. 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.

Jaime 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 Chicago, IL 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 Chicago, IL 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 Jaime 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 mini-van may be ready for a fuel injector cleaning.

What To Do In Case Of An Accident in Forest Park

December 8th, 2009 by saavedra9

Screeching tires, crunching metal – it’s an accident! If you’ve ever been in a car accident in Forest Park, 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 Chicago 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 IL 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 Stone Park and Maywood motorists by putting out flares, using your flashers or lifting your hood. Call Forest Park emergency services as soon as possible. Tell the operator if medical or fire help is needed.

Always file a Chicago 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 Chicago vehicle, license plate and vehicle identification number. Most IL 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 Jaime Auto Service at 773-582-5524

Recommended Service Intervals

December 4th, 2009 by saavedra9

Everyone in Chicago 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 mini-van, the complexity is multiplied. You’d need a computer to keep track of everything. We’ll, that’s how Jaime 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 Chicago 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 Chicago area to be taken into account. Talk about these things with your Chicago service advisor at Jaime 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 Chicago 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 Chicago 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 Jaime 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.
