I do it all the time, I like to run it every tank and I go heavy in the fall and spring. I usually do a bottle to every 10 gallons when I go heavy, otherwise a bottle to 25 for regular fillups. keeps it running tight. Get it down to 50 gallons or so and dump all 5 in, it cleans up carbs and injectors, cleans carbon too
