    Steven in TX

    Fantastic oil.

    This is the only oil Ive ever used where I can actually tell a difference in the way my bikes run. Ive been using it in both my street & dirt bikes for a couple years now & wont use anything else period. Expensive , yes a bit but so are engine repairs. Cheap insurance to me.
