Is There a Relationship Between Increased Engine Noise and Engine Oil?
3 Answers
Increased engine noise is related to engine oil. Improper use of engine oil, such as using a viscosity that does not match the engine, can easily lead to carbon buildup, resulting in louder engine noise. Solution: Use the oil grade specified in the vehicle manual and avoid mixing different brands of engine oil. Generally, loud engine noise is caused by carbon buildup. Here are several specific reasons for increased engine noise: 1. Aging or loosening of engine mounts. Engine mounts are rubber blocks between the engine and the frame. Solution: Tighten or replace the engine mounts. 2. Improper use of engine oil. Using oil with a viscosity that does not match the engine can easily cause carbon buildup, leading to louder engine noise. Solution: Use the oil grade specified in the vehicle manual and avoid mixing different brands of engine oil. 3. Engine misfire. An engine misfire occurs when one or more cylinders are not functioning properly. Solution: Check the condition of each ignition coil and spark plug in the cylinders.
I believe the increase in engine noise is definitely related to the engine oil. Engine oil is like the blood of the engine, responsible for lubricating all metal components and reducing friction noise during their movement. If the oil level is too low, dirty, or if expired or incorrect viscosity oil is used, it may lead to insufficient lubrication. When engine parts rub directly against each other during operation, the noise increases. I've encountered similar situations while driving - when checking the dipstick shows the oil level below the minimum mark, the noise does become louder. Delayed oil changes can also cause this, as aged oil contains sediments that affect its flow properties. However, don't just focus on the oil; other possibilities need to be checked too, such as loose piston rings or bearing issues. Otherwise, just addressing the oil might mask the real problem. It's best to regularly check the oil condition and follow the manual's oil change intervals - usually every six months or 5,000 kilometers - which can prevent most noise-related issues.
The increase in engine noise is indeed related to engine oil, which I've personally experienced. Last year, my car became increasingly noisy on the highway, and it turned out the oil had turned black and deteriorated, significantly reducing its lubrication effectiveness. Engine oil is supposed to form a protective film, ensuring smooth and quiet operation of components like pistons and crankshafts. Once it's insufficient or expired, increased metal friction leads to louder noises. It's important to regularly check the oil level; in the morning before starting the car, use the dipstick to ensure it's between the standard marks. If not changed in time, old oil can accumulate more carbon deposits, leading to abnormal noises. Of course, there could be other reasons, such as a clogged air filter or ignition system failure, but always start with the simple check of whether the oil needs changing—it can save a lot of repair hassle and financial loss.
