BEST Oil for motorcycles that call for 20W-40 !!!!!

I ride a Yamaha VMax and the manual calls for 20W-40 oil. There are plenty of geniuses on the internet that will tell you “Just use 15W-40”. They think they know more about the oil than the engineers who designed the engine. What’s the cheapest thing you can do to prolong an engine? Change the oil with high quality oil !!! AMSOIL Is not the cheapest oil you can buy, but in my experience, it is the best !!!
Bottom Line
Yes, I would recommend this to a friend.
