How to Read the Oil Dipstick?
2 Answers
Method for reading the oil dipstick: The oil dipstick has an upper limit and a lower limit. When the engine oil level is between the upper and lower limits, it indicates that the oil quantity is normal and can continue to be used. If the oil level exceeds the upper limit of the dipstick, it may lead to increased carbon deposits; if the oil level reaches the lower limit of the dipstick, it can cause cylinder misfiring in the engine, and prolonged use under such conditions may affect the lifespan of the car's engine. The oil dipstick is a simple-structured liquid level gauge used to measure the static height of the engine oil, reflecting whether the engine's oil reserve is within a reasonable range. It is more accurate to check in a stationary state.
I check the engine oil myself every time I service the car, and it's actually quite simple. First, park the car on level ground and turn off the engine for ten minutes to let the oil flow back into the oil pan. Locate the yellow or orange pull ring, pull it out firmly, and wipe the dipstick clean with a tissue. Reinsert it all the way and then pull it out again. At this point, check the oil level: it's ideal if it's between the upper and lower limit marks, but if it's below the lower limit, you must add oil. Pay special attention to the condition of the oil—darkening is normal oxidation, but if there are metal shavings, it indicates engine wear, and a milky emulsion like milk tea foam means water has entered and needs immediate repair. I also smell it—a gasoline odor might indicate blow-by gases in the cylinders. Developing a habit of regular checks can avoid major repairs, especially for older cars, which should be checked at least every two weeks.
