How to check car oil.

1. Time to check the oil.

Be sure to check when the car is cold (e.g., not running overnight) because the oil will splash when the car is hot, and the dipstick will be inaccurate. The correct time is: after the engine is turned off, let it stand for 15 minutes and then check the oil dipstick, if you need to check it often, you can check it before starting the vehicle in the morning, and the oil level height at this time is also accurate.

2. Check the location of the engine oil.

When checking the dipstick, make sure that all four wheels of the car are parked at the same horizontal height, which means that there should be no tilt in the front, back, left and right. As soon as the body is tilted, the oil level in the oil pan changes and the measurement results are inaccurate. There is a relatively simple way to judge is to park the car, neutral gear does not pull the handbrake, if the car can stop still, it is basically horizontal, of course, the situation of left and right tilting is best to avoid.
