How to Check Engine Oil?
1 Answers
To check engine oil, follow these steps: 1. Open the car hood; 2. Pull out the oil dipstick; 3. Insert it into the engine oil. Methods to determine oil cleanliness: 1. After pulling out the dipstick, smell it closely. If there is a strong sour odor, the oil has deteriorated; 2. Rub the used oil between your thumb and forefinger repeatedly. If you feel impurities, poor viscosity, or roughness, it should be replaced promptly; 3. Hold the dipstick at a 45-degree angle under light to observe the oil droplets. Clear visibility of no metal particles indicates good condition; 4. Place a few drops of used oil on a clean white filter paper. After the oil spreads, high-quality oil will leave no powder residue.
