Car Servicing - The Maintenance Free Myth

2017-09-29 09:02:04

Sometimes we hear people say, "What's up with all this maintenance stuff? Modern cars just don't break down." While it is true that today's vehicles are extremely reliable, they are also becoming increasingly complicated and use more exotic materials than ever before. All that complexity demands higher tolerances for everything. For example, most car owners don't realize how high tech automotive fluids have become,  fluids such as engine oil, transmission fluid, coolant and brake fluid.

Did you know that a modern engine would not run for more than a few months using motor oil formulas from 30 years ago? Today's automotive fluids contain a much higher percentage of additives to protect your vehicle's components from premature wear and corrosion. Time and distances march on for all of our cars. Please don't think we're using scare tactics to get you to take care of your maintenance - but here are some personal stories we've heard to emphasize and show how important it is to get things done when they are due. Names are withheld to avoid embarrassment to those who should know better. Even though they should know better, it usually comes down to real life: time and money. But they are tales of "a stitch in time saves nine".

The first comes from someone who bought a used pick-up truck for his son. The oil was clean and all the fluids were topped off. A short time later, the truck overheated and shut down. The repair shop diagnosed the problem: the radiator pan was corroded and dumped the coolant. Even though the coolant level was correct, it was clear that the coolant had never been completely replaced - just topped off from time to time. While this kept the engine cool, all of the anti-corrosion additives had worn out; the coolant became acidic and ate through the radiator pan. The cost: hundreds of dollars and four days in the shop. This demonstrates the need to get your coolant exchanged on schedule.

The second: a teenage daughter and a curb. Dad's little girl runs into a curb when she turned into a shopping center and blows the tyre. The problem came when Dad didn't get an alignment. The impact was hard enough to ruin the tyre - so it was enough wreck the alignment, but instead of an alignment after the first tyre, Dad ended up buying a second tyre a few months later - and then an alignment.

Situation: son and wife with cars from the same vehicle manufacturer with essentially the same engine. The staff member checked the son's maintenance schedule and saw that it needed a timing belt replacement 150,000 km. He had it done - it cost several hundred dollars. His wife's car had done about 97,000 km, so it should be ok for a while. Right? Wrong. The problem was that the wife had the turbo charged version. Its belt was scheduled for replacement at 100,000 km.  At 107,000 km, the belt snapped on the motorway. The valves all crashed down into the cylinders at high speed, the entire head was destroyed and it had to be replaced. The cost: several thousand dollars. Does he wish he had checked the vehicle manufacturer’s maintenance schedule? You bet he does - every time he passes a big-screen TV.

The team at Oil Changers recommend taking care of little things before they become big things. And when you take care of the little things, you can make your car run better, plus, it is more economical to run. Remember to save those maintenance records. It'll show potential buyers that you've taken care of your vehicle and it may help you get a better price. Or when you buy a used car, check those records. If there aren't any, assume that the maintenance hasn't been done and take it to Oil Changers for an inspection. Take care of unperformed routine maintenance sooner rather than later.

Let us help keep your older Vehicle running

2016-07-31 09:34:02

A lot of people want to hang onto their older vehicles. They're dependable and they're paid for. 

There are a lot of vehicles on the roads that have run past the 200,000 or 250,000 kilometers. Is there something that their owners are doing that keeps these vehicles on the road? Or did they just win the “lemon lottery” and luck out by getting a particularly good vehicle? Not surprisingly, most of these owners have something in common. They never skip an oil change. Can keeping a vehicle on the road for 250,000 kilometers really be that easy for drivers?

Actually, it makes sense. Oil is the lifeblood of a vehicle. Clean oil ensures that the engine will run efficiently and staves off the build-up of sludge that can eventually damage engine parts. Oil changes remove dirty oil and replace dirty oil filters, keeping an engine clean and running smoothly, just like eating right keeps our hearts healthy by preventing build-up in our arteries.

There's another reason why not skipping an oil change can result in a longer life for your car. When you bring your car in to Oil Changers for an oil change, all of the fluid levels are checked and topped off. If these fluids are depleted, dirty or low, they can damage the engine.

If a fluid is significantly low, it may indicate a leak somewhere, leading to an inspection of relevant parts. This inspection and the replacement of the worn part can prevent repair bills and maintain the health of the engine.

During an oil change, your technician will also do a quick check for worn belts or hoses, uneven tread wear, leaking shock absorbers and other signs of wear and tear. This advance notice allows the owner to replace parts before they break down and possibly damage your vehicle.

The oil change is also a good time to review any other services that the vehicle might need. Many car owners rely on their professional technicians at Oil Changers for good motoring advice that will keep older cars running well.

Parts wear out on older vehicles. There's no avoiding it. As the odometer chugs upward toward 250,000 kilometers, the vehicle will need several batteries, maybe an alternator and a water pump, a new set of shocks and possibly a set of brake rotors. But these items—all together—add up to far less than the cost of a new car.

Good car care and preventive maintenance will help keep your vehicle on the road and running past the age when most of us have given up and headed back to a car lot. 

So treat your car right: Take good care of it and don't skip the check-ups at Oil Changers.

The Easy Way to Save Money on your car

2016-06-26 08:44:02

The biggest news story may be different every day, but there's one topic that seems to come up over and over again – the price of fuel. If you feel like most of your paycheck goes into your fuel tank, this post is for you. Here are several basic things people can do to greatly reduce their fuel consumption, save money, and help the environment. You can really improve your fuel economy by how you drive – but first, here's a review of things you can do for your car that'll save fuel no matter how you drive.

The first one for drivers is keeping tyres properly inflated. That can save up to 2 kms/litre. Driving on low tyres is like driving through sand – your car just has to work harder. Most service centers will check your tyres for free, so just ask Oil Changers. Make a habit of checking your tyre pressure whenever you fill up. Most fuel stations have an air hose you can use for free.

Another important item is to keep your air filter clean. An air filter all clogged up with dirt and bugs doesn't let enough clean air through to efficiently burn fuel. Using a dirty air filter will cost you quite a bit in reduced fuel economy. Worn spark plugs can cost more fuel. A spark plug can fire as many as 3,000,000 times for every thousand kilometers driven. Check the vehicle owner's manual for replacement recommendations.

The biggest item is the oxygen sensor. This device provides the engine management computer with information it needs to fine-tune the fuel/air mix. When that's messed up it can cost vehicles up to four kilometers per litre. Of course, there's dirty or substandard oil. Dirty oil causes extra drag. The wrong grade may be too thick. That's another 1/2 a kilometer per litre right there.

One item people seldom think about is their gas cap. A worn, loose or missing gas cap can cost more in fuel than you realise. Adding up all of these worn, missing or sub-par items leads to a significant increase in fuel economy! And with current petrol prices, the cost really adds up. Taking care of these simple maintenance items will save you at the pump. 

Now most vehicles aren't missing on all of these items, but think about which ones might affect you right now! And don't forget tune-ups, dragging brakes, low transmission fluid, fuel system cleaning, wheels out of alignment, PCV valve, fuel filter and other services spelled out in your owners' manual.

Oil Changers knows all this stuff and can tell you when you're scheduled to take care of each item. Create a system of your own to track your service schedules, or just use the computer system at Oil Changers – which may also be updated with recall notices and maintenance schedule items from your vehicle manufacturer.

Training Received by Technicians

2016-05-24 08:10:03

When your car breaks down or just needs some routine service, it can make you a little nervous. Because your car's so important to your life, you need to be back on the road as soon as possible and with the problem fixed right the first time.

We've been checking into some of the training our technicians receive, and we're very impressed. It's amazing how much knowledge and skill goes into diagnosing and repairing a modern car. So it's not like when your uncle worked on his hot rod over the weekend.

Today there are four cylinder engines that make more power than the V-8's in luxury cars did 20 years ago. A new V-6 Toyota Camry could beat an old Ferrari in a race to 60 mph.

Our engines are more and more powerful and also very reliable. This is all due to engineering. But the benefits come drivers at the price of simplicity. Modern cars are so much more complex from a mechanical standpoint that it makes your head spin.

Then there's the electronics. Some cars now have several networked computers controlling most of the engine functions and many other vehicle functions as well. We tend to  take all of this sophistication for granted – but somebody has to fix it when it breaks.

It's a real challenge for the Automotive Service Centres to keep up. It requires a high level of commitment on the part of the Technician and the service centre as well. In addition to the training, there's the financial commitment to purchase the diagnostic and repair tools as well.

So where do New Zealand technicians go for training? There are many sources. It's usually a combination of formal classroom training, training provided in the service centre by Automotive parts and equipment manufacturers, on-line courses and home study courses. There are many independent certifications available all the way up to Master Technician.

Service centers also have a lot of other resources available as well. No one can know everything, so service centers like Oil Changers subscribe to data services, technical libraries and even on-line communities that can help them with they run into a difficult problem.

It's like those medical diagnosis shows on TV. Here are the symptoms – what's the diagnosis and treatment. Diagnosis is every bit as much an art as a science. We all want everything to be simple, straight forward and cheap – and sometimes it just isn't.

So, be more relaxed next time you take your vehicle in. You can trust the professionals at Oil Changers. You're in good hands. The more you know, the more comfortable you can be with your automotive service decisions.

Severe Service Requirements for your Vehicle?

2016-03-23 08:43:54

A lot of drivers have asked whether or not they should use their severe service maintenance schedule, which is listed in their car owners' manual. It can be somewhat confusing, so we decided to consult an expert. Cricket Killingsworth is from QMI/Heartland, a manufacturer of automotive products and fluids. She's been in the automotive business for over 30 years and is a speaker, trainer, and a writer.

Cricket says there's so much confusion on this topic because, "Most owners' manuals actually have two maintenance schedules. Sometimes these are called 'regular service' and 'severe service'. Sometimes they're simply called Schedule 1 or A and Schedule 2 or B. A severe service schedule recommends that things like an oil change, air filter replacement, and transmission service be done more often: either in fewer miles or in less time."

Foreign and domestic vehicle manufacturers create a specific schedule for each vehicle they manufacture. So there isn't one generic schedule that applies to all cars. In addition to your owners' manual, New Zealand automotive repair centers (including Oil Changers) subscribe to information services that provide the auto maintenance schedules for every vehicle - so they can help drivers know when to take care of needed services. Below is a typical definition for severe service.

  • Most trips are less than seven kms
  • Most trips are less than 15 kms and outside temperatures are below freezing
  • You drive regularly in very hot weather
  • The engine is at low speed most of the time (not on the freeway)
  • Stop and start driving
  • You drive in dusty or muddy conditions
  • You routinely tow a trailer, haul heavy loads or carry a car-top carrier.

It's common sense for drivers: Just a few minutes at higher speeds allows the moisture in the oil to evaporate. Very short trips, or trips of less than 15 kms when it's very cold, don't allow the engine to heat up enough to get rid of the water. And water in the oil leads to damaging sludge. Also, towing and heavy loads raise operating temperatures and cause fluids to break down faster. Dusty and muddy driving means that more dirt will get past the air filter to contaminate the fuel system and engine oil.

The bottom line is that you need to decide for yourself if the regular or severe service schedule is right for you, based on your driving habits. Look at your owners' manual, or talk with your Oil Changers service advisor who can help you know which schedule to follow.

Here is what a fleet manager said recently: "Since city driving are generally tougher on vehicles than highway driving, we use the our manufacturer's severe service schedule as the basis for our preventative maintenance program. We massage those schedules over time, increasing or decreasing the service intervals so that they make the most sense. There is a little bit of art to go along with the science."

Make an honest evaluation of your driving habits. Unless you do mostly open road driving in moderate weather, you'll likely have a fairly good amount of severe service mixed in. Some drivers just want to play it safe and follow the severe service recommendations, rather than analyzing how they drive each month.

Ask us for help evaluating your driving and service needs.
