Storing a mower with no gas

[slomo]

Small engines are not designed to run 91 plus octane anyway.

Chainsaws, trimmers and some blowers need 89 or 91. read your engine manual.

Most all mowers, 87 is fine.

How do you "properly store" gasoline? I don't know. Everybody has their favorite witches brew of additives (or not) and a statement to "properly store" the gas, but nobody ever says how that is done. Temperature range? Container type? Sealed? Open to the air?

If you have an old gas can, open top for sure, replace the spout with a new style. They have O-rings that semi-seal the can. Keeps out moisture, air, bugs, leaves and grass.

I use a combination of these three products (in the pic below) in my fuel and have never had a problem starting engines in the spring after leaving fuel in my equipment (2 & 4 stroke) over the winter months. I use premium gas as I don't have access to leaded fuel around here.

For 2-stroke engines I always use Echo Red Armor oil. It's more expensive but worth it to me. Anecdotally, I have a 25 year old Lawn Boy push mower (original engine) that starts every spring on the first pull.

Everybody has something that works for them, this is just what has worked for me for the last several years, for what it's worth.

There was something about that Stabil 360. Yes it does a couple other things. Think it was it had less stabilizer in it than the regular formula? Something like that. I called them. Guy said use the old school formula. Always works for me.

I use 87 octane, 10% ethanol in everything from a chainsaw to my Ford Taurus and never have problems. Keep the fuel moving, store it correctly and you will be fine. Or you can buy premium fuel, Stabilizer, and think you are doing it right. To each his own.
