Engine Oil FAQs

What is car engine oil?

The primary function of engine oil is to lubricate the internal components of your car's engine. However, it also does a whole host of other tasks such as cooling your engine by more evenly distributing heat, cleaning it using built in oil additive detergents, improving the sealing, and inhibiting corrosion.

Which engine oil for your car/what engine oil to use?

You will generally find the recommended car engine oil grade/viscosity & specification within your vehicle's handbook, or you can use our engine oil lookup to make sure you're getting the right oil.
Which product you need to use will depend on your make, model, and variant of car, as well as other factors such as your driving style and the condition of your vehicle.

Why do engine oil grades and specifications matter?

Each vehicle's engine is produced and designed around a certain engine oil grade/viscosity plus a very precise specification. Oil specifications are varied to cope with the vastly different strains and stresses vehicle motors have to cope with (cc size, DPF, diesel, and petrol to name just a few). Therefore, to maintain the efficiency, lifespan, and performance or your engine you should always stick with the oil that your engine was designed to take (unless your vehicle is heavily performance modified).
