Engine oil level can be checked by: After the engine is turned off for about half an hour, pull out the oil dipstick and wipe it clean, then reinsert the dipstick and pull it out again to see the oil level. Engine oil, motor oil, or engine lubricant is a substance enhanced with additives in base oil, mainly containing anti-wear additives, detergents, dispersants, and multi-grade oil viscosity index improvers. The main functions of engine oil are to reduce friction and wear of moving parts, and to remove sludge (one of the functions of dispersants) and varnish (detergents) from the engine. It also neutralizes acids produced from fuel and lubricant oxidation (detergents), improves the sealing of piston rings, and cools the engine by carrying away heat from moving parts.

I've been driving for almost ten years, and checking the engine oil is routine for me. Doing it myself is worry-free and prevents potential issues. First, park the car on level ground—never on a slope—and wait a few minutes after turning off the engine to let the oil settle properly. Pull out that small dipstick, usually located near the top of the engine, wipe off the old oil residue with a clean cloth, fully reinsert it, and then slowly pull it out again, being careful not to get it dirty. Make sure the oil level is between the MIN and MAX marks—too low and it can wear out engine parts, too high and it affects cooling. I make it a habit to check every two weeks, also keeping an eye on whether the oil has turned black, which means it's time for a change. If it's low, top it up with the same type of new oil, filling to just above the middle mark—never overfill. Maintaining the right oil level can extend your engine's lifespan by tens of thousands of kilometers, saving money and being eco-friendly.

I just learned to drive not long ago and think checking the oil isn't too hard to grasp. Park on level ground, turn off the engine and wait a bit for the oil to settle. Take out that little dipstick in the engine bay, wipe it clean of oil marks, reinsert it, then pull it out again. The oil mark should be between the MIN and MAX indicators - too much or too little is no good. If it's low, top it up with the same oil grade, don't mix brands randomly. New drivers should remember to check regularly, like once a month, to protect the car from breaking down roadside. Keep it simple - just use paper towels and the spare oil bottle from the garage.

Checking the engine oil level primarily ensures the correct operating conditions. Park on level ground with the engine off for more than five minutes. Pull out the dipstick, wipe it clean, reinsert it, then pull it out again to check if the oil level is within the marked range. Perform regular preventive maintenance; if low, add the correct type of engine oil.
