I use it sparingly, about 2 oz. per 24 gallon fillup, and in the
fuel tanks only.

Thanks . . . I put some in my fuel tanks when I started using auto gas, and
started to see gray streaks along the right side of the engine
cowling--apparently coming from the exhaust. It wiped right off, but I didn't
know what it was. When I stopped using MMO, the streaking also stopped. Maybe
I used too much . . . any ideas what the gray streaks were?
