How to Check Engine Oil Level?

[ValerieRose]

Here are the steps to check the engine oil level: 1. Choose a flat surface and check with the dipstick 15 minutes after the engine is turned off. Before checking, remove the dipstick and wipe it clean with a tissue. 2. Then reinsert the dipstick until the handle is firmly seated in the tube. 3. Finally, remove the dipstick, hold it horizontally, and observe the oil level. If the oil level is at or below the minimum mark, you should add more oil. Here is some related information: 1. Engine oil, known as the lifeblood of a car, serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and provide cushioning and shock absorption for the engine. 2. Engine oil consists of two parts: base oil and additives. The base oil is the main component of lubricating oil, determining its basic properties, while additives compensate for and improve the shortcomings of the base oil, giving it new properties, making them an important part of lubricating oil.

Checking the oil level is actually quite simple, and I usually do it myself. Remember to park the car on level ground and wait 10 minutes after turning off the engine to let the oil settle. Open the hood and look for the yellow or orange pull ring with markings (that's the dipstick). Pull it out and wipe the oil off with a cloth first. At this point, pay attention to the two notches or dot marks at the end of the dipstick, which indicate the minimum and maximum oil levels. Reinsert the dipstick vertically all the way back into the tube and then pull it out again. Hold it horizontally to check the oil stain position. If it falls between the two marks, it's normal. If it's close to the lower mark, promptly top up with the same type of oil. Each time you check, also take a look at the oil's color. If it appears black, it's time for a change. A milky white color might indicate coolant leakage from the radiator mixing with the antifreeze.

Never check the engine oil immediately after turning off the engine, as the hot oil can burn your hands. I prefer to do it when the engine is cold, such as before heading out in the morning. For a more accurate reading, wipe the dipstick twice: the first wipe removes the initial residue, and the second reveals the true oil level. If the oil mark falls within the dotted area of the scale, it's safe. If it's below the minimum line, don’t panic—just add half a liter and wait 5 minutes before rechecking. Friends who often drive older cars should keep a spare bottle of oil in the trunk, especially before long trips. Some models with electronic dipsticks require accessing the oil level via the central display screen. If the oil can warning light appears on the dashboard, do not continue driving.

Last week, I taught my daughter how to check the engine oil and found three things beginners often overlook: checking before the car is fully stabilized (readings on a slope are inaccurate), reading without wiping the dipstick first (oil sticks to the inner walls of the tube), and checking immediately after driving (oil hasn't fully drained back). Remember to push the cleaned dipstick all the way back in until you hear a 'click' to ensure it's properly seated. After checking, tighten the oil cap securely—I once forgot to tighten it and ended up with oil splattered everywhere on the highway. Nowadays, new cars have electronic monitoring, but seasoned drivers still prefer manual checks—after all, the mechanical dipstick is the most reliable.

In winter, pay attention to the viscosity of the engine oil. Once I checked it at -15°C, and the oil was as thick as syrup, giving a much lower reading than actual. Later, the mechanic advised warming up the engine to normal temperature first, then turning it off and waiting five minutes before checking. For diesel vehicles, be even more patient as winter oil has poor fluidity. When checking the dipstick, find a well-lit angle or use your phone's flashlight. If the level is below the minimum mark, don't pour in oil aggressively—add no more than 0.5 liters at a time, as overfilling can damage the catalytic converter. By the way, during seasonal changes, it's recommended to also check if the oil viscosity suits the local temperature.

After learning the hard lesson of oil burning, I now check it every week. Here's a tip: use a white tissue to wipe the dipstick, which makes the oil level line particularly clear and allows you to observe the oil quality at the same time. Transparent golden yellow is the best, brown indicates it's almost due for a change, and milky white foam may mean the cylinder gasket is damaged. Remember not to wear gloves when checking; touching the dipstick directly with your hand makes it easier to feel if it's fully inserted. European cars often have issues with oil temperature sensor failures, causing the dashboard to give false alarms, but a manual dipstick check shows normal levels. Cars used mainly for short trips need more frequent checks, as excessive engine carbon buildup can accelerate oil consumption.
