Synthetic oil can be a multifunctional oil if you know the right place to use it. First of all, you can use it on the bike chain, clutch, and engine, which is pretty impressive on its own. Also, it can be a great liquid that you can use to protect the brakes and the gear of your Harley Davidson. It helps to reduce noise very effectively if you use it on the teeth of the gears. That way the gear shifts will be very less noisy and also it’s going to stay healthy for a long time.
