Make sure your car is on level ground. Start the engine, let it run for a short while, then turn it off. While your engine is still warm. Remove the dipstick, and wipe clean with a lint-free rag. Reinsert the dipstick fully, otherwise you will get a false reading. Remove the dipstick and check the oil level. If it is reading low, top up your oil using the correct grade as recommended by the vehicle manufacturer. Once or twice a month you should wipe over your engine parts and leads with a dry, soft cloth. It may also be beneficial to have your engine professionally steam cleaned once or twice a year. Note: Do not run your engine if there is no oil showing on the dipstick.
