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 accurate. The method for measuring engine oil is as follows: 1. Open the car's hood; 2. Pull out the oil dipstick; 3. Insert it into the engine oil. Methods to check the cleanliness of the engine oil include: 1. After pulling out the dipstick, bring it close to your nose and smell it. If there is a strong sour or foul odor, it indicates the oil has deteriorated; 2. Rub the used oil between your thumb and forefinger repeatedly. If you feel impurities, poor viscosity, or even a gritty sensation, it should be replaced promptly; 3. Hold the dipstick at a 45-degree angle under light to observe the oil droplets. If no metal particles are visible, the oil is in good condition; 4. Place a few drops of the used oil on a clean white filter paper. After the oil has soaked in, high-quality oil will leave no residue or powder.
