It makes a lot of difference whether you have a vented gas tank or not. I have an old Troy-Bilt tiller with a Kohler engine. If I don't drain the fuel out and I let it sit for more than about a month, the gasoline in the float bowl develops into a gel. It doesn't bother it until the engine warms up, and it melts the gel enough to let it get sucked up into the main jet and stalls the engine out. The gas tank has a vent cap and the...

Unless you need to mow your lawn at a moment's notice, your mower will appreciate a nice fresh can of gas in the spring. Best post in this thread so far.

The smallest container offered for sale is good to treat 10 gallons of gas. My lawnmower only takes 1 gallon. Would the Sta-bil last the TEN YEARS it would take to use it all up? Two years from date of opening the bottle -- it says so on the bottle. I believe the bottles even come with a place on the label to mark this...

Every vehicle has a vented gas tank. If the gas tank didn't allow air in, the fuel pump would be sucking against vacuum as the level of fuel in the tank dropped. So called "sealed" fuel systems don't allow venting of gas fumes out, but they have to let air in.

Sta bil works. However you're not going to have a problem with a car for a few weeks.

If the gas is going to be used up and refeshed, not a problem If you are going to have that same gas over the winter, I would add Sta-bil. The alcohol in gas significantly reduces the shelf life.

I always store my Miata from Nov 1 thru March ? (first warmer day after salt has been washed away). In the past I never used Sta-bil and never had a problem. Now I use Sta-bil and still never have a problem. So 4 month old gas isn't gonna cause any real issues from my experience.
