I used it in mine it is gas with out the excess water in it. It cleans the mower engine and it runs better, be sure to use it once a week with your regular fuel or just use it regularly it is cheaper then fuel and it is like fuel but the mower is a smaller engine it will work fine.
So, you can but now I want to leave the topic of grass. How do you struggle against leaves? Personally, I am eager to buy Ryobi leaf blower P21081 and many people call me crazy because of it. They think this is useless advice but in reality, this is extremely important.
Yes you can. I do this with my lawn mower.
