Is it accurate to measure engine oil after the car has been parked overnight?
1 Answers
Measuring engine oil after the car has been parked overnight is definitely very accurate because the car is in a cold state at this time, and the oil has all flowed into the engine oil pan. However, you don't necessarily have to wait overnight to measure it. Usually, 10-15 minutes after turning off the engine, the oil will completely flow back into the oil pan, and you can directly pull out the dipstick at this time. How to check the dipstick: The dipstick has a very distinct feature, which is a pull ring, making it easy to identify. When using it, take a towel, pull out the dipstick, wipe it clean with the towel, and then reinsert it into the dipstick slot in the engine, pushing it all the way in. Precautions for using the dipstick: After parking overnight or for half an hour, make sure to accurately observe the correct oil level on the dipstick. Do not just look at one side of the dipstick; check both sides and take the lower reading as the accurate measurement.
