RE: Amsoil
Hi,
Any good 2-stroke oil will work fine at 40:1. If you want to stick with Amsoil, Dominator would be the choice at 40:1. Visit your local motocycle shop and any of their high performance 2-stroke oils work great. Klotz, Belray, Mobile 1, Pennzoil . . . . . . . Just make sure that it is an oil for air cooled engines.
