Keeping Your ‘Old Faithful’ Auto Running

March 16th, 2010 by gilmour28

At Gilmour’s Automotive Repair 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 Oshawa 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 Oshawa 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 Oshawa 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 Gilmour’s Automotive Repair. 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.

Deep Clean Your Fuel System At Gilmour’s Automotive Repair

Today we’re talking about fuel system cleaning. The first thing to know is how important it is to have a clean fuel system. You need fuel to go, and the cleaner your fuel system, the more efficiently the fuel will burn. That means more power and better fuel economy.

A clean fuel system saves money at the pump. We guess you could say, it all starts and ends at the pump. One of the most important things you can do to keep your fuel system clean is to buy good quality gas. Major brands have detergents that keep gum and varnish from rapidly building up in the fuel system.

So buying cheaper gas can actually cost you in the long run. Now, most cars on the road are more than five or six years old. That means they’ve had time for some dirt and rust to start accumulating in the fuel tank. This junk needs to be filtered out of the fuel before it hits your engine. That’s the fuel filter’s job.

When the fuel filter is clogged, the dirty fuel will bypass the filter and go on up to the engine where it can clog fuel injectors and get into the cylinders. That could do some damage. So you should have your fuel filter changed when recommended. Check your owner’s manual or ask your service advisor if your fuel filter is due for replacement.

The fuel then goes up into the throttle body. This is another area where varnish and gum can accumulate. A professional fuel system cleaning will use a combination of special cleaning chemicals and old fashioned swabbing to clean out the throttle body. Now, the fuel injectors are the last stop in the fuel delivery system.

It’s real important to keep those fuel injectors clean. The fuel injectors need to deliver a precise amount of fuel, at exactly the right time, in a particular spray pattern. They just can’t do that if they’re dirty. Dirty fuel injectors really rob power and waste fuel.

It is important for the fuel system proper, but there are a couple other things that will help keep your engine clean as well. Of course, air is mixed with the fuel before it’s burned. Dirty air means dirt gets into your engine, so you need to replace your engine air filter when it’s dirty.

The PCV value routes unburned fuel that escapes into the lower engine back up into the intake system to be burned. A sticky PCV valve needs to be replaced to make sure that system is working properly and the breather filter needs to be replaced if it’s dirty as well.

Do all these things and your engine’s air and fuel will be as clean as possible. You’ll get much better fuel economy and better power

The Harm In Skipping An Oil Change For Oshawa Drivers

March 4th, 2010 by gilmour28

People in Oshawa have been hearing a lot about higher oil change intervals these days. Maybe you’re wondering: What are the key issues?

Some new vehicle manufacturers in Oshawa are now recommending much higher oil change intervals than they have in the past. As much as 5,000 to 8,000 miles or more. This practice came under scrutiny when four of the largest new car manufacturers announced that owners like those in Oshawa were experiencing engine damage resulting from these higher oil change intervals.

The manufacturers’ standard oil drain service for particular vehicles was scheduled at around 7,500 miles. People following these recommendations were experiencing engine damage. It turns out that oil sludge was building up. This caused small oil passages to clog and engine parts to fail.

What causes oil sludge? It’s a factor of time and mileage. There are hot spots in every engine that cause oil burn off that leads to sludge. Also, water from normal condensation can build up in the oil. This water also creates sludge. Severe driving conditions lead to more rapid sludge formation.

Visit Gilmour’s Automotive Repair in Oshawa, Ontario L1H 7R7

Severe driving around Oshawa includes short trips under four miles or trips under ten miles in freezing conditions. The engine just doesn’t get warm enough for the water in the oil to evaporate.

Severe conditions are at the heart of the problem. Stop-and-go driving, towing, dusty conditions, heavy loads, very hot or very cold temperatures, a car top carrier – these are all conditions that would suggest that the severe service schedule should be considered.

The severe service schedule has much shorter oil change intervals. People in Oshawa just need to honestly evaluate how they drive to determine if they should change their oil closer to the severe service schedule, or to the standard schedule.

Some types of sports car will give oil change reminders. But it’s important to know how that reminder is determined. For some, the reminder simply comes when the standard mileage interval has rolled around. Others use a computer algorithm that takes into consideration the number of cold starts, trip length, engine temperature and so on. It’s programmed to approximate where on the standard/severe service spectrum you fall. Some more expensive vehicles actually have sensors that test the cleanliness and effectiveness of the oil.

For the rest of us, better safe than sorry should be the guiding principle. Talk with your Oshawa service advisor at Gilmour’s Automotive Repair and work it out together. Find out what kind of oil the factory sends out in your vehicle. Sometimes it’s a premium grade that costs more than standard oil – but it may be what’s needed to meet a higher factory recommended interval.

If you’re realistically conservative, standard grades of oil will take care of you year after year. If you want to push the limits, ask for a premium grade oil to give you extra protection.

So, what happened with those manufacturers with the problems from higher oil change intervals? They ended up extending the engine warranty for parts that were affected by oil sludge. But they had a stipulation – they lowered the oil change interval and the vehicle owner had to provide proof of oil changes at the new lower interval to keep the extended warranty.

Fuel Filter Service in Oshawa Ontario

February 26th, 2010 by gilmour28

There are a surprising number of small, inexpensive parts that can lead to expensive engine damage when they fail. It doesn’t seem right.

Fortunately a lot of those things can be taken care of in routine maintenance. They may not be easy to remember, because it is a long list, but your service center at Gilmour’s Automotive Repair can help you know what’s scheduled to be taken care of.

Some of us in Oshawa Ontario really don’t look forward to going in for an oil change and then getting a list of the other things the manufacturer recommends.

But automotive maintenance is all about prevention, and addressing small problems before they get big. Let’s take the fuel filter for example.

You may not know this but the median age for private vehicles on our Oshawa Ontario roads is over nine years. When cars get older, five years or so, they’ve accumulated a lot of dirt and rust in their gas tanks. If that dirt gets into the engine it can cause thousands of dollars worth of damage. So somewhere between that dirty gas tank and the price of a great vacation – is the lowly fuel filter: a very inexpensive part that doesn’t cost too much to replace. And your car’ll just run better too.

A clogged fuel filter can’t let enough fuel through. You might notice at first that your car is running fine around town, but struggles or sputters on the Oshawa Ontario freeway or when you accelerate. Enough fuel can’t get through to meet the demands of higher speed. If it gets bad enough your engine might just shut off or not start at all, which could be dangerous.

Some fuel filters have a bypass. When they get clogged, they allow dirty fuel to move around the filter element so dirt ends up in the engine. We’ve already talked about how expensive that can be.

The fuel filter is even very important for newer cars. The fuel is still dirty even if there isn’t rust in the tank. It’s just that the fuel filter will need to be changed more frequently as the vehicle gets older.

How often should you change your fuel filter? Check your owner’s manual. Your Oshawa Ontario service advisor at Gilmour’s Automotive Repair can tell you as well. It’s usually around thirty thousand miles or so. Ask if it’s time for a full fuel system cleaning as well. They often go hand in hand.

It’s good to know that your Oshawa Ontario service center has your back. When you’re motivated to maintain your vehicle’s performance and to reduce operating costs, you’ll think of Gilmour’s Automotive Repair as your ally – and maybe even your memory.

When Are Your Tires Worn Out?

February 19th, 2010 by gilmour28

Hey Oshawa, are your tires worn out? What is the standard for our Ontario streets? How can you tell on your sports car?

While there may be legal requirements for the Oshawa area, there are safety concerns that go beyond meeting minimum replacement mandates.

2/32 is the depth of the tire tread wear indicator bars that US law has required to be molded across all tires since August 1, 1968. When tires are worn so that this bar is visible, there’s just 2/32 of an inch – 1.6 millimeters – of tread left. It’s that level of wear that’s been called into question recently.

We’re referring to the Consumer Reports call to consider replacing tires when tread reaches 4/32 of an inch, or 3.2 millimeters. And the recommendation is backed by some very compelling studies.

The issue is braking on wet surfaces in and around Oshawa. Most of us think of our brakes doing most of the work, but if you don’t have enough tread on your tires, the brakes can’t do their job. When it’s wet or snowy, the tread of the tire is even more critical to stopping power.

Picture this: you’re driving over a water covered stretch of road near Oshawa, Ontario. Your tires must be in contact with the road in order to stop. That means that the tire has to move the water away from the tire so that the tire is actually contacting the road and not floating on a thin film of water.

Floating on the surface of water is called hydroplaning. So if there’s not enough tread depth on a tire, it can’t move the water out of the way and you start to hydroplane.

In the study a section of a test track was flooded with a thin layer of water. If you laid a dime on the track, the water would be deep enough to surround the coin, but not enough to cover it.

A car and a full-sized pick-up were brought up to 70 miles per hour, or 112 kilometers an hour and then made a hard stop in the wet test area. Stopping distance and time were measured for three different tire depths:

  • New tire tread depth
  • 4/32 of an inch
  • 2/32 of an inch

So what happened with the 2/32 tires on the car? Get this – when the car had traveled the distance required to stop with new tires, it was still going 55 miles an hour. Stopping distance was nearly doubled to 379 feet and it took 5.9 seconds.

Wow! That means if you barely have room to stop with new tires, you would hit the car in front of you at 55 miles an hour with the worn tires.

Now, with the partially worn tires – at 4/32 of an inch – the car was still going at 45 miles an hour at the point where new tires brought the car to a halt. It took nearly 100 feet more room to stop and 1.2 seconds longer. That’s a big improvement. We can see why Consumer Reports and others are calling for a new standard.

Of course, stopping distances were greater for the heavier pick-up truck.

How do you know when your tires are at 4/32 of an inch? Easy; just insert a quarter into the tread. Put it in upside down. If the tread doesn’t cover George Washington’s hairline, it’s time to replace your tires. With a Canadian quarter, the tread should cover the numbers in the year stamp.

You may remember doing that with pennies. A penny gives you 2/32 to Abraham Lincoln’s head. The quarter is the new recommendation – 4/32.

How do people feel about replacing their tires earlier? Well, tires are a big ticket item and most people want to get the most wear out of them that they can. But do you want that much more risk just to run your tires until they are legally worn out?

For us, and we would guess for many, the answer is “no”.

Maintaining Your Older Car In Oshawa Ontario

February 10th, 2010 by gilmour28

The government mandates a lot of equipment on cars in Oshawa Ontario: emission devices and control computers, safety equipment like airbags and crash worthiness requirements. All of this is great for the Oshawa Ontario 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 Oshawa area are driving their old cars longer. The average car is now over nine years old. Two thirds of vehicles on the road in Oshawa 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 Gilmour’s Automotive Repair 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 Oshawa Ontario 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 Oshawa Service Advisor

February 3rd, 2010 by gilmour28

We find that a lot of Oshawa service and repair at Gilmour’s Automotive Repair 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 Oshawa 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 Oshawa. 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 Oshawa 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 Oshawa 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.

Fuel System Cleaning to Improve Performance in Oshawa, Ontario

January 28th, 2010 by gilmour28

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 Oshawa, Ontario 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 Oshawa, Ontario. 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.

Gilmour’s Automotive Repair 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 Oshawa, Ontario 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 Oshawa, Ontario 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 Gilmour’s Automotive Repair 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 sports car may be ready for a fuel injector cleaning.

Nitrogen Fill For Tires in Oshawa Ontario

January 21st, 2010 by gilmour28

So, everyone in the Oshawa Ontario area knows how great helium is – you know, party balloons, squeaky voices. But a lot of people around Oshawa 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 Gilmour’s Automotive Repair.

Nitrogen has actually been around for a long time in the Oshawa Ontario commercial sector, but it’s just starting to catch on for private vehicles in the L1H 7R7 zip code area.

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

Contact Gilmour’s Automotive Repair to learn more about nitrogen in your tires
You can find us at:
250 Wentworth St. East
Oshawa, Ontario L1H 7R7
Or call us at 905-433-4161

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 Oshawa 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 Gilmour’s Automotive Repair 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.

Recommended Service Intervals

January 12th, 2010 by gilmour28

Everyone in Oshawa 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 sports car, the complexity is multiplied. You’d need a computer to keep track of everything. We’ll, that’s how Gilmour’s Automotive Repair 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 Oshawa 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 Oshawa area to be taken into account. Talk about these things with your Oshawa service advisor at Gilmour’s Automotive Repair 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 Oshawa 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 Oshawa 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 Gilmour’s Automotive Repair 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.
