Engine Oil

Engine oil is a key component of your car's engine system, lubricating its parts to reduce friction and damage. Discover the ideal engine oil for your vehicle to keep it running smoothly, from high-quality brands like Shell Helix and Castrol.

Why and when should I change my engine oil?

Engine oil is designed to keep all the parts of your engine moving and working correctly. Over time it collects dirt and becomes less efficient, eventually requiring a change.

It’s recommended you change your engine oil every 5,000 miles. If you drive a lot, particularly in challenging conditions, it’s worth changing it at 3,000 miles.

What kind of engine oil should I use?

Find the right engine oil for your car by using our convenient part finder tool. Simply type in your registration number and we’ll show you the oils best suited to your car. You can then choose between brands, and whether you’d like synthetic oil or semi-synthetic.

What happens if I put the wrong oil in my car?

Using the wrong engine oil can negatively impact performance and damage your car's engine system. This is why we only show you engine oil that is compatible with your vehicle, providing peace of mind.

Can you go back to regular oil after synthetic?

There is nothing wrong with switching back and forth between synthetic and regular oil, as the two are compatible with each other.

What are the symptoms of thick engine oil?

If engine oil is too thick, it won't properly lubricate the moving parts of your engine, so you might experience trouble starting your car (particularly on a cold day).
