I'm getting 2000 miles per quart since my XPAG engine rebuild several years
ago. It's all hard driving, if running 4500 rpm on the highway is considered
hard driving. I use Marvel religiously, even on my B. After using it several
times to loosen a sticky valve, I figured - why not use it all the time? At
first thought one might wonder what good a few ounces of light oil can do in
a whole tank of gasoline. But consider that's the only lubrication a two
cycle engine gets! BTW, I'm not experiencing any fouling using Marvel.
