How to Solve Overfilled Engine Oil in Diesel Cars?
2 Answers
Find a set of infusion tubes, suck out some engine oil from the oil filler port, and adjust the oil level to slightly below the highest mark on the dipstick. Ask a professional at the 4S shop to operate.
Once while servicing my diesel car, I accidentally overfilled the engine oil. After starting the engine, it sounded unusually muffled and vibrated more than usual. I quickly checked some materials and found that excess oil increases internal pressure, causing foam formation which affects lubrication. Prolonged operation could damage seals or pistons. I immediately stopped the engine, found level ground to let it cool, then checked the dipstick - sure enough, it was above the maximum mark. Without professional tools, I used a manual oil extractor to slowly remove the excess oil through the dipstick tube. After about ten minutes, the level returned to normal. Upon restarting, the engine sounded fine again. This taught me a lesson - now I always use a measuring cup to precisely portion oil before adding, avoiding guesswork. Additionally, regular oil level checks are crucial. The maintenance manual recommends checking every 5,000 kilometers - this habit has saved me considerable repair costs. Paying attention to engine condition and addressing minor issues promptly helps extend vehicle lifespan.
