What is the correct way to measure engine oil?
1 Answers
Before measuring the engine oil, pull out the dipstick, wipe it clean, reinsert it, and then pull it out again to check the oil level. If the oil level is between the two marks on the dipstick, it indicates the oil quantity is normal. Generally, you should wait for about 15 minutes after turning off the engine to allow the oil to stabilize before checking. Ensure the vehicle is parked on a level surface when checking the oil to guarantee an accurate measurement. The first time you pull out the dipstick, wipe it clean before reinserting it, then pull it out again to check the oil level. This ensures an accurate and intuitive reading of the oil quantity. Park on level ground. To ensure the accuracy of the dipstick measurement, the car must be parked on a flat surface. This is easy to understand—if the surface is uneven, especially on steep ground, any measurement will be inaccurate. Cold engine condition: Measure the engine oil using the dipstick when the engine is cold. This is a detail many car owners overlook. Some might ask: Is this really necessary? Based on years of experience, it absolutely is. Engine oil lubricates the engine's moving parts and flows inside the engine to reduce friction. When the engine is hot, some oil remains adhered to the components. Measuring the oil level under these conditions will result in inaccuracies, typically a few millimeters off.
