I’ve always used Amsoil but lately it seems my Harley motor was sounding louder. I tried Lucas synthetic because of the reviews. Made the engine worse. Researched other oils and came across Quicksilver synthetic motorcycle oil 20w50. I decided to try it and it definitely made the engine sound much better. My Harley seemed to run better. If this oil holds up it will be my go to oil. I’ve been riding for over 50 years and I must say there is something to this oil. Made by Mercury motors who works very hard to have some of the best products. We will see how it holds up. I am hoping it proves to be great!
