Which Engine Oil Produces Less Noise?
3 Answers
If the viscosity of the engine oil does not meet the predetermined requirements, the noise can be very loud, especially from the valves. It is best to use synthetic oil with appropriate viscosity. Here are some details about engine oil: 1. Function: Engine oil is crucial for the engine. It not only lubricates but also cleans, seals, buffers, prevents rust, and dissipates heat. 2. Regular Replacement: The performance of engine oil degrades over time, so it needs to be replaced regularly. Failing to change the oil for extended periods can accelerate engine wear.
I've been driving for over a decade and have encountered engine noise issues many times. Finding an oil that reduces noise is actually quite important. Initially, I used conventional mineral oil, and the engine was quite loud, especially during long highway drives—it felt like driving a tractor. Later, I switched to full synthetic oil, such as Mobil 1's 0W-20 variant, and the difference was immediate. The engine ran much smoother, and the noise was significantly reduced. Even during daily commutes, listening to the radio became much more pleasant. This is mainly because it has low viscosity and excellent fluidity, allowing it to quickly penetrate engine gaps and reduce friction. I also found that regular oil changes are crucial. If you go beyond six months or 8,000 kilometers without changing the oil, even high-quality oil can thicken, causing noise to return. Overall, choosing low-viscosity formulations from full synthetic brands like Shell or Castrol makes a huge difference in noise control compared to semi-synthetic oils—it just makes driving more enjoyable.
As a new driver who just got my license, I'm particularly concerned about choosing engine oil that reduces noise. After reading many experiences shared by car enthusiasts online, they mentioned that low-viscosity oils like 5W-30 can significantly reduce engine noise due to better lubrication. I personally tried Mobil's synthetic oil, and after the change, the engine sound became much quieter—the loud rumbling during cold starts almost disappeared. This helped me understand that the strong anti-wear additives in the oil can cushion impacts between components. Additionally, I learned a small tip: when purchasing, look for brands with API certification, such as SN-grade full synthetic oil, which is more stable and durable. With reduced noise, driving becomes more enjoyable, and it also helps avoid engine wear, saving on long-term repair costs. Overall, low-viscosity synthetic oil is my top choice, and trying different brands can help find the most suitable one.
