Introduction to Diesels

2018-09-06 07:00:06



Something you've probably seen and heard a lot more about recently is diesel engines. We're not talking about semi-trucks and buses; we're talking about diesel engine cars, pick-ups and SUVs.

Most people in are surprised to learn that around half the cars on the road in Europe have diesel engines. Nearly all import brands offer a range of diesel engines abroad – even the ultra-luxury brands like Mercedes and BMW. 

As diesel engine technology has improved with the introduction of Common Rail diesel engines over the past several years we are starting to see more diesel options offered over by vehicle manufacturers.

Why are so many people interested in diesel engines? Well first off, diesel is more energy dense. There's more power in a drum of diesel fuel than there is in a drum of petrol. The result? Better performance and improved fuel economy.

Diesel powered vehicles get about 20 percent better fuel economy. As for power – why do you think that the majority of new utes are being sold with diesel engines?

If you think back to the late 1970's and 1980's and even into the 1990's, you may shudder when you think of the diesel powered cars of the day – noisy, smoky, under-powered beasts that rattled and shook their passengers. Modern diesels sold have evolved considerably.

They are quiet, clean – and powerful. They're so refined that many drivers can't even tell they're driving a diesel powered vehicle. In addition to fuel savings, diesels generally last longer than petrol engines because of their heavy duty construction.

There is a lot of buzz about hybrid cars at the moment. Some manufacturers are looking into diesel-electric hybrids in years to come to make a good idea even better.

Every year, manufacturers introduce new diesel models. 

New diesel vehicle owners need to know that properly maintaining a diesel engine is somewhat different than a petrol engine. Fluid change intervals are different. Emissions control devices have to work harder to filter diesel fuel and to scrub the exhaust so you will need to pay attention to that. And the fuel injection system operates at much higher pressures than petrol fuel injection systems, so it's important to keep your fuel system clean with a diesel.

The good news is that Oil Changers is keeping up with the new diesel technology and will be able to advise you on maintaining your diesel.

When we tell you to look for more diesels you won't be looking for smoky tail pipes as a clue. You also won't be listening for that familiar big rig rattle. And, you certainly won't be waiting for them at the stoplight, because modern diesels are as quick as their petrol counterparts.

Engine Air Filter

2018-06-25 07:54:03

Many drivers have found themselves in the following situation: They go to get their oil changed and their friendly service advisor at Oil Changers recommends a new engine air filter. They say yes, but don't know what an air filter is or what it does.

If this has happened to you, rest assured that you did the right thing by getting a new one. But you should never be too embarrassed to ask your service advisor for more information. It's your vehicle and you have a right to understand what you're paying for.

Let's review: "What does an air filter do?"

Air is the focus of this discussion. What is the air like outside right now? Can you see any smog? Is it full of pollen? How about dust? Anyone with hay fever can tell you that there's plenty in the air that you can't see. Well, the engine air filter's job is to clean that air before it goes into your vehicle engine, to mix with the fuel and be burned. Without an engine air filter, the inside of your vehicle engine would be extremely dirty from all the gunk that was burned in the cylinders.

In fact, your engine needs 12,000 times as much air as fuel for it to run. That little filter does a very big job. It's no wonder that the air filter gets dirty and needs to be replaced. Think about a vacuum cleaner. When the bag gets full of dust and dirt, the vacuum doesn't clean as well. It can't move enough air to create good suction. A clogged engine air filter is the same way - the vehicle engine can't get enough air to burn the fuel efficiently. That means less power and reduced fuel economy.

That's why your owner's manual has recommended that you change your filter at regular intervals. Of course the conditions you drive in will affect how quickly the filter gets dirty. If you drive where it's very dusty or where there's lots of pollen or pollution, you may need to change the filter sooner. The filter is easy to check visually, so your service advisor can quickly make the call. He might recommend immediate replacement or simply let you know that it is getting close and that you'll need to replace it soon - like at your next oil change.

Because a severely dirty vehicle air filter hurts your vehicle, most people find that a new air filter pays for itself in better fuel economy before the next oil change.

The better your car breathes, the better it runs - kind of like people. And don't worry - if you have a question or don't understand a recommendation just ask your Oil Changers service advisor.

The Oil Changers Guide to Saving Fuel: Get Rid of Dirty Oil

2018-01-21 09:41:04

A lot of us are asking ourselves the same question lately: how can we save on fuel? We are all cutting back, if not in fuel consumption, then in other areas of our lives.

Preventive Maintenance

Preventive maintenance is an important way that you can save fuel by improving fuel economy. One of the easiest and most effective ways to do that is to keep the oil in our vehicle topped up and clean.

Oil lubricates your vehicle's engine and keeps it running smoothly. If you're running low, there is increased friction in your engine. Friction creates drag, which means it takes more fuel to keep the vehicle motor running. This all translates to lower fuel economy.

Check your oil to make sure the engine is getting all it needs. Your owner's manual and service advisor at Oil Changers will tell you the proper viscosity (or weight) and type of oil for your vehicle.

Responsible Car Care

Dirty oil leads to a buildup of dirt and sludge inside your engine, which also increases friction. So even if there's enough oil, you're still getting that extra drag that reduces your fuel economy. That's why your owner's manual recommends getting your oil changed regularly. It's good advice.

While you're checking your oil, you should take a quick look at your transmission fluid as well. Your transmission also needs clean, adequate fluid to work efficiently. An inefficient transmission also translates into lower fuel economy.

Your service advisor at Oil Changers will be able to check your oil and other fluids, top them off or change them if necessary.
Your owner's manual will have recommendations on how often you should check your oil and transmission fluid, but you can also consult with the team at your local Oil Changers. The types of roads you drive on, how you drive, the climate where you live and the air quality in your area can all affect how often you should change your oil.

And don't forget that this will improve our environment as well. Improved efficiency translates to fewer emissions. Changing your oil as scheduled doesn't just help your vehicle (and your wallet), it helps keep the air clean as well.

Fuel Filter Service

2017-10-18 01:51:03



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 local Oil Changers team can help you know what's scheduled to be taken care of.

Some of us really don't look forward to going in for an oil change and then getting a list of the other things that 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 roads is over nine years. As vehicles get older they can accumulate small amounts of dirt in their fuel tanks. If that dirt gets into the engine it can cause thousands of dollars of damage. So somewhere between that dirty gas tank and the price of a great vacation is the lowly fuel filter.  Generally its an inexpensive part that doesn't cost too much to replace and your vehicle will run better too.

A clogged fuel filter can't let enough fuel through. You might notice at first that your vehicle is running fine around town but struggles or sputters on the open road 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 vehicles. 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  Oil Changers service technician  may be able to tell you as well. It's usually around 50,000 kilometers or so but can vary greatly between vehicle's.

It's good to know that your service center has your back. When you're motivated to maintain your vehicle's performance and to reduce operating costs, you'll think of Oil Changers as your ally - and maybe even your memory.

How Do You Save Fuel?

2013-02-13 12:00:00

No one likes to spend a chunk of change at the petrol pumps. Rising fuel prices, however, have spurred drivers to focus on how to improve their fuel economy. Nationwide, drivers can travel hundreds of thousands of kilometres less each month during times of high fuel prices but we still need to drive (we are car-lovers after all!), so it makes sense to try and increase our fuel economy however we can.

Let's look at a real life example. This man has one of those really big SUVs. Lots of kids and horses to haul around, you know. His family was planning a four day camping trip. Here's what he did to cut his fuel costs:

First, he installed a new engine air filter. Then he had his service center change his oil, flush his cooling system and service his front and rear differentials along with the transfer case. He also made sure his tyres were up to the recommended pressure.

Now this cost a few hundred dollars. But keep in mind, it all needed to be done anyway – it was all scheduled, and some of the work was overdue.

So he headed out, loaded with nine people and pulling a trailer loaded up with everything needed for four days of camping. When the trip was over, he tallied his fuel costs. Turns out, he got the best fuel economy on that vehicle up to that point. It had improved 25 percent! He saved $48.00 on that trip alone and the savings keep on coming every day.

Here's a quick summary of what you can do to save fuel. First get caught up on your routine maintenance. Nearly every scheduled service item can boost your fuel economy . If it's time for a service then get it sorted at Oil Changers. That's one big item.

If your check engine light is on, have your service advisor at Oil Changers figure out why and fix it. Check engine light problems don't help with your fuel economy.

Proper tyre pressure and wheel alignment can really help as well. Try not to carry around a bunch of stuff. An extra 50 kg or so can cost a kilometer per litre.

Now you may not want to hear this, but the single biggest fuel waster for most people is their right foot. Zooming away from stop lights can really waste fuel. Take it easy on our roads: don't speed and plan ahead.

Finally, you may have noticed that we haven't mentioned any magic pills or devices that will double your mileage. That's because there aren't any. Some may help a bit, but there are a lot of "miracle fuel saver" scams out there. Don't shell out any to swindlers, you need it to buy gas!

Do some research and check with your friendly team at your local Oil Changers before spending your hard earned cash.
