I have a small bottle of amsoil, and have run it at 100-1 with no ill effects. The stuff I have is VERY thick, seems to have high tack, is quite a bit harder to mix with gas, and is twice as opaque when mixed at 100-1 then regular stuff at 50-1.
In the future I will be mixing it at a lower ratio for added insurance, but its probably perfectly fine with normal demand equipment.
My uncle's 024 av super has been using optimal at 100-1 since it was new, has cut hundreds of cords of wood and still runs great. However, we were warned not to store the saw with anything less than 50-1 to prevent RUST in the bottom end.
