How to check a car’s engine oil

Oil is essential for an engine to run at its best — here’s how you can check your car’s is in its best condition

Oil is to an engine like oxygen is to humans — an absolute necessity to keep it going.

An engine consists of several metal moving parts, creating a lot of friction. Oil works to prevent these components from wearing out quickly and failing.

It is, however, a consumable product, and as such requires regular checking and the occasional change to keep your car running smoothly. Not sure how to check engine oil? Here’s how…

Look for the manufacturer guidelines

Before doing anything, get out the owner’s handbook for your vehicle. In there, you’ll find information about oil recommendations for the vehicle and how often the lubricant should be changed. Although it’s vital to regularly check the oil, if you’re approaching an interval then it’s even wiser to have a look as you could risk serious damage to the vehicle if you go above the suggested mileage for a change.

Prepare the car

To get an accurate picture of your car’s engine oil, there are a few steps to take in order to prepare the vehicle before taking a look.

Park on level ground and allow the engine to cool down for at least 10 minutes if it’s warm.

Locate the dipstick

Pop the bonnet and find the dipstick for your car. On most modern vehicles, it’s usually bright yellow and easy to see. You may have been asked to locate it on your driving test, but if you didn’t — or you’ve simply forgotten — the vehicle handbook should be able to help.

Grab the tissue

Once you’ve found the dipstick, pull it out and wipe it with a clean tissue. Use this as an opportunity to locate the oil indicator markings, which are usually either two small holes or raised bumps. Then, place the dipstick back in.

Check the oil level

Once again, remove the dipstick but this time lay it flat on another clear piece of tissue and look where the oil comes up to. If it’s between the indicator markings, then you’re at a good level.

If it comes below, then you need to add more oil — or run the risk of increased engine wear. Too much? The oil will foam up and result in poor lubrication, and ultimately less friction. While you can opt to drain the oil yourself from underneath the car, it’s always best to seek professional help if this is needed.
