How to add oil to your car
Check the oil after the car has rested for 5 minutes.
If you check the oil right after turning the car off you will get an inaccurate reading, as some of the oil will still be at the top of the engine. Keep the car on a level, even surface as well to make sure you aren't checking the oil on a slant.
Most auto manufacturers require you check the oil after the car has been warmed by starting it in place for 3-5 minutes. Check your owner's manual if there is any doubt.
