Lifter noise is a common issue with many engines, and there are a variety of ways to combat it. Some people swear by using thicker oil, while others find that other methods work better for them. Ultimately, it may take some trial and error to figure out what works best for your particular engine.
One reason why thicker oil might help with lifter noise is because it can provide a more cushioning effect between the moving parts in the engine. This can help to reduce the amount of metal-on-metal contact, which can in turn reduce the amount of noise that is produced. Additionally, thicker oil can help to coat and protect the engine components from wear and tear.
However, it’s important to keep in mind that using thicker oil can also have some drawbacks. For one thing, it can increase fuel consumption since the engine has to work harder to pump the thicker oil through its system. Additionally, thick oil can make it more difficult for the engine to reach its optimal operating temperature, which can lead to increased wear and tear over time.
If you’re struggling with lifter noise, experiment with different oils until you find one that works best for your engine without causing any negative side effects.
