It is very important to have your vehicles oil changed every 3 months or 5,000 km. Engine oil is the life blood of your engine. Its job is to clean, cool and lubricate the engine. If the oil is dirty, performance of the vehicle is compromised.
Dirty engine oil allows particles to become abrasive and cause accelerated wear to the valve train, crankshaft and bearings. All oil fed components do not perform at their optimum with dirty oil. Dirty oil causes clogging and sludge issues which will further wear the components.
It is a lot less expensive to have your vehicle serviced every 5,000 km then to replace an engine prematurely.
