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 engine 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. We have a wide variety of engine oil types on offer in this range, including 0w20, 0w30, 5w40, and 5w30 engine oil.

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, while being more cost-effective.

When should I check the engine oil level?

It’s recommended you change your engine oil every 5000 to 7500 miles to help ensure the performance and longevity of your engine, although you may need to do it earlier if the engine oil light indicates that pressure is low. Oil that has been left for longer can become clogged with dirt particles which reduce its ability to lubricate, increasing wear on your engine and reducing efficiency. However, it’s important to check it much more often than this, especially if you’re embarking on a long journey. It’s best to check your engine oil at least every other week.

How to do an oil change

To conduct a car engine oil change, you’ll need to remove your oil filter and drain the sump of any existing oil. Once this is done, attach a new oil filter. Find the oil fill port, which 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.

Engine oil isn’t the only essential car lubricant we stock in this range. Browse our wider collection now for antifreeze, brake fluid, power steering fluid, and transmission fluid and gear oils.
