Gas in a lawnmower during the winter?

Do I burn of all of the gas in my lawn mower or do I leave it in there? Does gas turn into ice? The lawnmower will be in an well insulated area but no heat will be on. In the winter its about 30 or 40 Degrees in the building.

    You need to put a fuel stabilizer in it. That will keep the fuel from breaking down over the winter, you can pick up a bottle pretty much anywhere and just follow the instructions on the label.

  • perfectlybaked says:

    I think it will be fine. If it is easy, you shouldn’t leave a gas tank with gas that just sits there, but the industry would warn consumers if this is serious.

    IF YOU DONT EMPTY TRY ADDING A LITTLE DRY GAS

  • vikingsron says:

    It actually is better for an engine to have fuel in it during extreme temp. storage but you need to put a fuel sabilizer in it I’ve used sta-bil in a boat before and had no problems

  • Harith Rahman says:

    Ideally you should take the gas out before you store the mower. It can gunk up your engine and then youd have to convince the wifey to buy you a new ride on lawn mower with the cup holders and XM radio; you woulnt want that would you? You can buy fuel stabilizers to mix w/ the fuel in the mower before you store it and it will help the fuel not break down into gunk over time. it wont turn to ice unless it gets really cold, ive never had it happen in colorado.

  • Madcitymatt says:

    Burn it out by running it out of gas. Remove the spark plug and put a SMALL (a few drops)amount of engine oil in the cylinder, hand tighten the spark plug. Ready for storage. See your owners manual. That’s what I do for my four stroke Lawnboy.

    It is acceptable to use a fuel stabilizer in the gas and leave it in all winter. Just be sure that after you add the stabilizer, be sure to run the engine long enough to get the stabilized fuel into the carburetor. Top off the fuel tank right to the top so there is no air space to allow evaporation.

  • cheesey says:

    It is ok to leave gas in a lawn mower over the winter, it might freeze if there is any water in the gas. When in doubt drain it out.

  • neighborhoodnurseryinfo says:

    It is best not to leave gasoline in an engine for any period of time longer than a few months, no matter the time of year. However, winter is hardest on the lawnmowers fuel system.

    Gas does not turn into ice, so you may ask- Why is it Important to Winterize?
    Gasoline left in an engine’s fuel tank and carburetor can degrade over time. During storage, gasoline can interact with air and moisture to form gums and deposits. This process is a factor of evaporation and time as much as temperature. This is why you should not store gasoline in the engine’s fuel tank for any inactive periods longer than one to two months.

    After the fuel is drained, run the engine until it stalls. You no longer have fuel to breakdown in the carburetor, gumming the small holes that control fuel flow.

    If it is difficult to drain the gas, or there is too much in the tank to run dry, (you don’t want to waste fuel and time running a lawn mower in your driveway for 20 minutes), fuel additives are now an acceptable alternative. Add the additive according to instructions, let the engine run a few minutes to get the additive into the carburetor and store.

    On an environmental note, gasoline will also evaporate from the gas tank over the winter months and dissipate into the air. When you drain the tank, store the gas in one of the new sealed gas cans, or use it in your car, you can get a few miles out of it. The world is changing, we all have to do our small part to make it a better place.

    A gas stabilizer will work or you can just run it out of fuel. The other person was right. If you leave gas in the tank, it will turn to a gummy solution that will clog your fuel line and carb. It can also absorb moisture which is just as bad. That is why I use the mid-grade gas in my engines. The extra additives in the gas prevents the moisture and gumming problems. I use no additives, but I do start and run them once a month for about five minutes. Good luck.

  • Deborah S says:

    Either drain it or put a chemical in it that will stabalize the fuel. Condensaton from changing temps can get in to your gas tank.
