There is a special oil level measurement device sticking out of one side of the engine block called the dipstick. It is a metal rod with a small ring at the top.

Pull this out and wipe it on a clean paper towel or rag.

Re-insert it and pull it out again. Many dipsticks need to bend to be re-inserted, so you might only be able to get it to go back in when it’s in the same orientation that it was when you took it out. Read the oil level on the stick and note its appearance.

It is normal for modern oils to be slightly dirty even after a short period of use, but if the oil is very dark, have it changed soon.

To get an accurate reading, you should check the oil after the vehicle has been sitting for at least a few minutes, so that most of the oil has flowed back into the reservoir at the bottom of the engine.

If the level on the dipstick shows “full”, that’s fine, but if the level shows “low”, either put some in yourself or ask someone to do it for you.

To add oil you will have to locate the large cap at the top of the engine block that unscrews or lifts off.

Add a small amount of oil at a time, frequently checking the level on the dipstick.

After some experience, you will learn that a certain distance on the dipstick translates to a certain amount of oil. Consult your owner’s manual for information on the proper type of oil for your car and weather conditions.

Do not forget to put the oil filler cap back, unless you want an unbelievable mess, and the possibility of engine damage.
