Will adding too much engine oil have any impact?
2 Answers
Adding too much engine oil will have impacts, including: 1. Creating unnecessary resistance to the crankshaft rotation, affecting power output; 2. Reducing engine power, causing sluggishness, muffled sounds, and increased noise; 3. Worsening exhaust emissions and damaging the catalytic converter; 4. Leading to engine oil leaks. The standard for adding engine oil is to keep the oil level between the minimum and maximum marks on the dipstick. The method to check the oil level is: 1. Park the vehicle on a level surface; 2. Pull out the dipstick after 10 minutes of parking; 3. Hold the dipstick vertically to the ground to check the oil level.
As someone who enjoys tinkering with cars, I've encountered the issue of overfilling engine oil, and honestly, the impact is significant. Excess oil causes excessive agitation when the crankshaft rotates, creating foam and bubbles, which drastically reduces lubrication effectiveness. This increases internal friction in the engine, leading to faster component wear. Elevated oil pressure can push seals, resulting in oil leaks or blue smoke from burning oil, and fuel consumption also rises due to increased resistance. In severe cases, excess oil can seep into the combustion chamber, causing carbon buildup that affects the exhaust system. Regularly checking the dipstick is crucial—before every maintenance session, I ensure the oil level is between the upper and lower marks. If overfilled, using a syringe to extract some oil can prevent long-term damage. Safe driving and vehicle health rely on these small details; don’t let minor mistakes turn into major problems.
