Why do I need to change my oil?

Motor oil serves many purposes. Its primary function is to lubricate and protect, but it also keeps your engine cool and running clean. By changing your oil frequently, you remove by-products of combustion such as acid, soot, abrasives, water and unburned fuel. All of these substances can have damaging effects on both the performance and life of your engine.

You should check your owners’ manual for their recommended oil change service. However, we recommend for ultimate protection that you change your motor oil every 3,000 miles / 5,000 kms (or 3 months, whichever comes first).
