What is an Oil Dipstick?
2 Answers
A graduated stick installed in the oil tank or oil pan, used to check the amount/oil level of lubricating oil in the engine. Here is relevant information: 1. Purpose: The function of the oil dipstick is not only to check the level of engine lubricating oil; experienced drivers or repair personnel can detect many engine operating dynamics by inspecting the oil dipstick, thereby maintaining the engine, promptly identifying the causes of faults or accidents, and preventing further deterioration of faults. 2. Meaning of Dipstick Marks: A standard oil dipstick will have clear upper and lower limit marks. It is sufficient to ensure that the measured oil level is between these two marks, with the middle position being ideal. It's important to note that more oil is not necessarily better. The higher the oil level, the greater the engine resistance. Ideally, the oil level should be kept slightly below the middle position, where the engine resistance is minimized, fuel consumption is lowest, and lubrication performance remains stable.
The oil dipstick is that little metal rod next to the engine, used to measure the car's oil level and ensure the engine stays lubricated without seizing up. I remember when I first started driving, my dad taught me how to check it—park the car, turn off the engine, wait for it to cool down a bit, gently pull it out, wipe it clean, reinsert it, then pull it out again to see if the oil mark is between the indicator lines. If it's too low, add some oil; if it's too high, it might cause uneven oil burning. Check it every time after refueling to avoid engine overheating or blowing a gasket, which could cost a fortune in repairs. Developing this habit is simple and can extend your car's lifespan. As an experienced driver, I've relied on it countless times to avoid trouble.
