I think it'd be good dribbled into the carb at a fast idle then drowning the eng with the last ounce of it then letting it sit overnight then taking it out for a blast (plugs may need cleaned to start it) to clean the combustion chamber . Into the gas itself I think it's snake oil and in the crankcase I wouldn't want to dilute my oil with it
