Car engine oil is a vital part of your motor... pay attention to your oil change intervals, check and top up your levels between services, choose a high quality oil that's of the right specification, that way you'll maximise the efficiency of your motor and extend your vehicles life. If you're unsure what type of engine oil your vehicle requires, normally you'll find the specs in your handbook, as a rule of thumb the higher quality oils are fully synthetics and are ideal for high performance, for general day to day driving semi synthetics are great and for more basic engine types mineral oils are fine.

The most obvious function of car engine oil is to lubricate, but car oil also protects against corrosion of engine components and cleans deposits and contaminants that can arise as by-products of combustion. Oil is also responsible for a large percentage of the cooling by circulating warmth more evenly though out the engine block.

A few common questions about oil answered:  

What is a Car Engine Oil?

The primary function of an engine oil is to lubricate the internal components of your cars motor. However it also does a whole host of other tasks such as, engine cooling, by more evenly distrusting heat around, cleaning, using built in oil additive detergents, improved sealing, utilising the correct viscosity of the oil, and inhibit corrosion, by using the oils built in oil additive package.

What engine oil to use

You will generally find the recommended car engine oil grade / viscosity & specification within your vehicles handbook, or you can use our Oil & Parts Finder, you'll also find great advice on motoring forums.

Why do engine oil grades and specifications matter

Each vehicles motor is produced and designed around a certain engine oil grade / viscosity plus a very specific specification. Spec's are very varied to cope with the vastly different strains and stresses vehicle motors have to cope with (cc size, DPF, diesel & petrol to name just a few). Therefore to maintain your engine efficiency, life span and performance you should always stick with oil your motor was designed around (unless it is heavy performance modified).
