Keeping your engine oil topped up is crucial to keeping your engine performing. The oil in your car’s engine helps to keep the moving parts running smoothly, dragging away any debris and protecting against damage. Your oil works hard, and over time can evaporate, drip away or lose its effectiveness.You should check your oil levels regularly and top it up when needed, it should also be changed regularly - as often as every year.

\r\n\r\n

It can be confusing to know what kind of oil you need, whether it’s part-or fully synthetic and what viscosity. If you know the difference between 5w30 oil and 10w40 oil, then you’ll find everything online. If you need some help, supply a few details and our oil finder tool will select the right oil for your car. You can also learn more about moto oil in our essential car oil buyer’s guide. It’s also worth checking your owner’s manual (if you can remember where to find it!).

\r\n\r\n
