The directions say to use the treatment in a full tank of gas and I'll bet the snowbower's tank is only 1 or 2 gallons. Adding the whole cleaner container to such a small volume of fuel might damage some of the snowblower's components. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Should of been using this long ago *by J***M on May 18, 2025* I literally watch my MPG jump up .3 within one tank, my mpg count after 6000 miles was steady at around 26.5 and after using this stuff and driving around for 1 tank of gas, it jump up to 26.8.
