Which Brand of Engine Oil Reduces Engine Noise
2 Answers
Engine noise can be reduced by using fully synthetic engine oil. Currently, many brands offer fully synthetic oils, such as Mobil, Castrol, Shell, Liqui Moly, Fuchs, Motul, Amsoil, Pennzoil, Great Wall, Tongyi, and HKS. When selecting engine oil, in addition to focusing on whether it is fully synthetic, you should also consider the oil viscosity based on usage conditions, seasons, and other factors. Here are the reasons for using fully synthetic engine oil: 1. Temperature range: Synthetic oil has a wider temperature range compared to semi-synthetic and mineral oils. 2. Lifespan: Synthetic oil is less prone to deterioration, has low evaporation loss, and lasts longer than conventional oils. 3. Multiple advantages: It has excellent chemical stability, good radiation resistance, high oil film strength, fewer foams, good lubrication, and less wear. 4. Engine protection: Fully synthetic oil has reduced thermal degradation, saves fuel, and provides better engine protection.
I drove an old car for over a decade, and the engine noise was incredibly annoying. After switching to Shell's synthetic oil, the noise noticeably decreased. Shell Helix series full synthetic oil has moderate viscosity, like the 5W-30 model, which provides good lubrication and wear resistance, reducing friction noise. I change it every 5,000 kilometers regularly, and over time, the engine has become much quieter. Castrol's synthetic oil is also good, offering high cost-performance, saving fuel while protecting the engine. Avoid mineral oil as it tends to age and foam, leading to more noise. Checking the oil level is crucial, as low oil can cause increased noise. Remember to choose genuine products with brand certification, as counterfeit ones can actually increase noise.
