How to Check Car Engine Oil?
2 Answers
To check car engine oil, follow these steps: 1. Open the car's engine hood; 2. Pull out the oil dipstick; 3. Insert it into the engine oil. Engine oil, also known as engine lubricant, serves to lubricate and reduce friction in the engine, assist in cooling, seal against leaks, prevent rust and corrosion, and act as a shock absorber. It is composed of base oil and additives, with the base oil being the main component that determines the basic properties of the lubricant. The reasons for changing car engine oil are: 1. To improve and enhance lubrication for the engine's moving parts; 2. To extend the engine's lifespan; 3. To improve the engine's lubrication conditions and reduce friction in moving parts.
Checking the car engine oil is something I do quite often, after all, the oil is the engine's lubricant. Without it or if it's dirty, the engine suffers. When parking, find a flat spot, turn off the engine, and wait for five minutes to let the oil flow back into the oil pan. Pull out the dipstick, wipe it clean with a cloth, then fully reinsert it. After a few seconds, pull it out again and carefully check the oil level line—it should be between the minimum and maximum marks to be considered normal. If it's too low, add new oil but don't overfill it; too much oil can cause foaming. Don't forget to check the color: new oil is a transparent light yellow, but it darkens to a deep brown with use. If it turns black or gray, it indicates carbon buildup and needs to be changed. I perform a routine check every month, especially before long trips, to prevent the engine from overheating, reduce wear, improve fuel efficiency, and extend its lifespan. The simple tools needed are just the dipstick and a white paper towel to check for dirt or metal shavings. Developing this good habit can save thousands in major repair costs.
