What to Do When Engine Oil is 2 cm Above the Maximum Level?
2 Answers
If the engine oil exceeds the maximum level by two centimeters, you can drain or extract a small amount of oil. When adding engine oil, ensure that the oil level is between the min and max marks on the dipstick. Here is some additional information: 1. If the oil level exceeds the max mark, it will increase the resistance during engine operation. 2. Increased resistance during engine operation will lead to higher fuel consumption. 3. Overfilling with oil may damage the three-way catalytic converter. When adding oil, do not let the oil level fall below the min mark; adding too little is also not advisable. 4. If the oil level is below the min mark, it can cause poor lubrication in the engine. Engine oil is often referred to as the lifeblood of the engine, as it plays roles in lubrication, cooling, cleaning, and sealing. 5. Without engine oil, the engine cannot function properly. Before adding oil, refer to your vehicle's maintenance manual, which specifies the exact amount of oil required for the engine. Simply add the oil according to the specified capacity.
I'm quite passionate about studying car maintenance, and when encountering an issue like the engine oil level being two centimeters too high, it's important not to panic. The first time I faced this, I immediately stopped the car and researched to learn that excess oil increases internal engine pressure, potentially damaging oil seals or causing leaks, and in severe cases, leading to blue smoke or even engine failure. So, before starting the car, use a clean oil extractor to remove the excess, bringing the level back between the upper and lower limits. Also, check if the oil was overfilled during the last service or if temperature changes caused expansion. Remember, always check the dipstick when the engine is cold before each oil change—this can save you from unnecessary repairs. Safety always comes first; if you're unsure, it's best to visit a professional shop for peace of mind and convenience.
