I have used 2 stroke mix gas in my lawn mowers if I forget to buy gas before heading out to mow for the day.....No excessive smoke or anything so far as I could tell...

I doubt it will be of any benefit at all but it will make filling at service stations difficult. These aren't 4-stroke race engines although Honda have made small race engines that peak at revs over 3 times what the GXH50 reaches.
I put 85% deisel in my Citroen BX petrol engine because the wrong fuel came out of the pump. I managed to drive 70 miles with no rear vision (the blue smoke was too thick to see through) before it finally wouldn;'t go any further and when I got the engine cleaned out and the fuel system cleaned the mechanic told me it had probably done the engine some good. It was expensive to fix though.
