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.
Check your engine oil weekly. The best time to check the engine oil level is when the car is warm and on level ground. Stop the engine and wait a few minutes for the oil to settle, remove the dipstick and wipe it clean. Push the dipstick all the way in, wait a second, and then withdraw it and check the level.
