Oil Change Services

One of the simplest, most effective and inexpensive ways to help protect the life of your car-especially its engine-is to change the oil and the oil filter regularly.

Oil is the lifeblood of your engine. It reduces friction, lessens wear, provides lubrication and forms a seal between the pistons, rings and cylinder walls while helping to cool engine parts. Without the cleaning action of new oil, carbon and varnish buildup would be toxic to the engine. And engine oil even dampens the shock and noise of moving parts.

Small wonder that engine oil and filter service is the car engineers’ most frequently recommended service. And with our oil change, or any other service, you can request a Atwill Service Centre Touch™ Courtesy Check. We’ll look inside, outside, under the hood and underneath the car, then explain the findings and give you a written report.


Engine Oil

Most cars on the road today use multi-grade oil—one that can work efficiently in cold and hot weather. A multi-grade oil is rated by two numbers, such as 5W-30.

 



About the oil classification system

Each engine oil comes with a classification indicating its viscosity, which is its friction or resistance to flow. In a multi-grade oil, the first number indicates how the oil will flow when it is cold. The lower the number, the lighter the oil and the better it will perform at lower temperatures. The second number indicates the thickness of that same oil at high temperatures. For example, a 5W-30 oil will flow as a 5-weight oil at -17.7 degrees Celsius and as a 30-weight oil at 98.8 degrees Celsius.

Why viscosity is a concern!

During cold starting, only a small amount of oil is present in the upper parts of engines. To lessen the friction when upper engine parts-such as the valve train, pistons, overhead cam and cam bearings-scrub against each other, a lower viscosity allows the oil to reach the components more quickly.

Why 5W-30 and 5w-20 oils are so popular

Many vehicles today leave the factory with 5W-30 or 5w-20 engine oil. Vehicle manufacturers recommend them because they are lighter oils that perform well in a range of temperatures and help improve gas mileage.

Synthetic Oils

Not all motor engine oils are 100% petroleum. Synthetic oils, which are primarily chemically compounded lubricants, are also available. They can provide:

  • Higher viscosity stability over a wider temperature range
  • Reduced oil thickening
  • Reduced wear and increased load-carrying ability

Which oil is right for your car?

The simplest and safest way to find out is to check your owner's manual...or talk to your Atwill Service Centre professional.

Oil Filters

Oil filters are designed to trap foreign particles suspended in the oil and prevent them from getting to the engine bearings and other parts.
