CHOOSING
THE RIGHT OIL
FOR YOUR CAR

Not all oils are made equal.

There are mineral oils and synthetics. Oils for high-tech engines, new cars, and even high mileage vehicles. And each of these oils can come in a wide selection of viscosities, from an even wider range of brands.

So how do you know when
you’ve chosen the right oil?

There are four key factors when choosing the right oil for your engine. They are:

The best thing to do is to check your vehicle’s handbook or owner’s manual. Often, manufacturers will suggest a range of oil viscosities for an engine. Knowing the importance of viscosity will help you choose the best oil for your engine.

The highs and lows of viscosity.

Viscosity is a fluid’s resistance to flow. Common engine oil viscosities include 5W-30 and 10W-40.

The "W" stands for winter, not weight as many people think. The lower the number here, the less it thickens in the cold. A 5W-30 viscosity engine oil would thicken less than a 10W-30, but more than a 0W-30.

An engine in a colder climate, where motor oil tends to thicken because of the lower temperatures, would benefit from 0W or 5W viscosity.

The number after the "W" represents the oil's resistance to flow at high temperatures. At the engine’s stable operating temperature, a 10W-30 oil will have less resistance to flow than a 10W-40.

When in doubt, check your owner’s manual.

Your owner's manual will advise you on the viscosity range for your local temperature conditions. You can of course consult your mechanic or car workshop for extra information.
