If you notice any of the symptoms stated above while behind the wheel, you need to check your engine oil. For an accurate check, make sure to park your car on flat ground after driving around for a few minutes. A warmed-up engine will help you read the dipstick. First, turn off the engine and open the hood of your car to find the dipstick. Pull the dipstick out of the engine and wipe off any oil. Then insert the dipstick back in. Pull it out after a few seconds and look at the dipstick to see how high the oil film reaches. Your dipstick has indicators, F (Full) and L (Low), and the oil level should be between each marking. Be sure not to put too much engine oil in your car since it may damage the engine.
