I have run Amsoil in my bike for years. Well last year I did about 600 miles on my bike. My second child is due any day. If I do 600-1000 miles this summer it will be alot. I feel like I am throwing money away using Amsoil. After reading so many threads I think Delvac would be fine. I am in NJ. What would you do? 2001 Hertage softail it now has 20k I bought it new.
