A fuel stabilizer helps keep fuel from breaking down. It also helps prevent engine corrosion due to gum and varnish deposits. A fuel stabilizer is essential if you want your lawn mower to run smoothly.

The 10 Best Fuel Stabilizers

All of these fuel stabilizers will help stabilize your fuel, but the top 3 are great because of how they remove ethanol and trash in the fuel, maintain the cleanliness of the fuel lines, and add more life to both the engine and the fuel system. To choose the right brand of fuel stabilizer, we recommend trying more than 3, but narrow it down to just 3 once you find the ones that work better for you.

The critical thing is to take notes concerning the maintenance, horsepower, RPM idol speed, starting, and how well the lawn mower saves on fuel. The fuel stabilizers will save in the pocketbook by not consuming as much fuel because the fuel is fresh and burning clean.

I have had several Toro products before and have had neighbors who recommended Toro products. BUT NO MORE!!!!
I purchased an electric Flex Force Power System- 60 V Max 22in Recycler Lawn Mower after having looked at videos and reviews on Youtube and talking to several dealers about purchasing an electric mower. Having just purchased a home on a small city lot, I felt I did not need the Poulan riding mower that I used for my quarter acre lot. So I purchased the Toro. What a mistake – WHAT A PIECE OF CRAP! It cuts poorly and mulches even worse. I have to cover the same ground two and three times in order to get the leaves picked up that blow in from my neighbor’s trees. We have no trees on our lot. And it is not even fall here in Minnesota. Worse yet, in the middle of cutting and mulching the light leaf cover on my lawn, the damn battery goes dead. So now I am sitting and waiting for two or three hours while the battery recharges.
I know – I should have known better. There’s an old saying, “Stick with what you know.” I didn’t do that and I bought this electric Toro machine thinking it would be better for the environment and still have near the same capabilities as my old Poulan. It doesn’t and all I can say is Toro has lost my trust. I’ll be selling this thing and buying a good gas powered walk behind that has the power to finish a lawn the size of a postage stamp city lot. And no – it won’t be a Toro!!
