I ran nothing but Amsoil in my 06 Ultra and it had 75000 miles without an issue. Next fluid change (and every one after that) will be with Amsoil on my 17 Ultra

 

Put it in my 09 xbone when I first bought it w/5000 miles fixin to change it in a week or two.

 

Never met an Amsoil distributor who did not preach using Amsoil

 

Have you met a Mobil 1 distributor that did it recommend that product ?

 

Nope. Add Lucas to the list

 

Yep amsoil will bring a bike with 100,000 miles on it back to running like new in one oil change. You will get 10 more MPG. . One thing amsoil is great at spamming web sights.
