Same fuel for a 2 cycle + 4 cycle?
Sure, why not? Ive had great luck w/ 2 stroke fuel in 4 strokes, and better fuel economy w/a loy of low end tork.
Just remember to break it in really really ritch,and dont try to lean it out like a 2 stroke.
Just my 2 cents worth, but Im sure if Im wrong some will tell us both.
good luck and have fun.
