Mobil One and other oil manufacturers recommend checking engine oil levels before driving your vehicle, when the oil is still cold. However, some manufacturers will recommend checking the oil after you've warmed up the engine, so check your owner's manual to find the specific recommendations for your vehicle.
How do you check the oil in a car? Check your car's engine oil by preparing the car, removing and wiping the dipstick, inserting and removing the dipstick a second time, and reading the oil level. If the oil level is on the crosshatched area of the dipstick, the level is fine.
