The oil filler cap on the BMW 3 Series is located in the recess above the BMW emblem. Method for checking engine oil: After turning off the engine, let it sit for 15 minutes before checking the oil dipstick. If you frequently need to check the oil level, you can do so in the morning before starting the vehicle, as the oil level at this time is also accurate. When checking the oil dipstick, make sure all four wheels of the car are on the same level ground, meaning there should be no tilt in any direction. A simple way to determine this is to park the car, put it in neutral without engaging the handbrake—if the car remains stationary, it is basically level. Oil dipstick: The oil dipstick is a slender metal rod inserted from the top of the engine down into the oil in the oil pan. The end of the dipstick has a marked scale to measure the oil level.
