What engine oil do I need? Consult your owner’s handbook or use our number plate lookup tool to make sure you’re buying the correct oil for your car. The main factor will be the oil grade. This refers to the number combination on the front of the oil bottle i.e., 5w30.

This is a guide to the viscosity of the oil at different temperatures, with the W referring to winter. The first number denotes how oil flows at cold temperatures or on start-up, with a lower number donating a thinner oil. The second number will refer to the oil viscosity at standard operating temperatures.

Another characteristic to consider is whether your oil is Synthetic or Semi-Synthetic. Synthetic engine oil is refined and purified and less viscous, performing better in extreme temperatures. Synthetic oil tends to be favoured in modern vehicles with turbos and features such as Start-Stop.

Semi-synthetic oils are simply a blend of synthetic oil and traditional mineral oil. This blend provides some of the performance benefits of fully synthetic oil, whilst being more cost-effective.

To conduct an oil change, you’ll need to remove your existing oil filter and drain the sump of any existing oil. Once this is done, attach a new oil filter. Locate the oil fill port, this will be located under the bonnet and have a symbol of oil on the top and pour in your fresh oil. To make sure you don’t overfill, refer to the owner’s manual for the correct amount and use the guides on the side of the oil bottle to confirm how much you’ve added.
