For how long? I've never fooled with them at all for over winter
following dad's footsteps and in 70 yr never had any issues at all. Of
course, it's pretty dry climate here...
When were in TN/VA for the roughly 30 yr where was more humid I'd simply
top 'em off for the (pretty short) winters to minimize volume available
to allow for condensation with same result.
Depending on how long of time, but for short periods of a couple of weeks,
full is better. If months or longer, then run it dry. That ethanol fuel is
especially bad to deteriorate in short periods of time.
If you can find it the ethanol free fuel is the way to go. It lasts much
longer. I have gotten in the habit of using it and also someof the Stay-bil
with it. That seems to work fine for me.
For the engines that have a fuel cutoff, I do cut it off and let the bowl
run dry every time and leave the gas in the tank. I do that to my 5 kw
generator that I start every couple of weeks. Mainly to burn out some of
the fuel in the tank so I can put in some fresh fuel. No often than I
really need it, I think I should just run all the fuel out and let it go at
that. I just want it to be ready if I do need it. Often I think about
adding a cut off to some of the other engines so I could do the same thing.
I use the ethanol free in all the small engines. Wish that it was not about
a dollar a gallon more than the regular gas so I could use it in the cars. I
don't think anyone but the farmers and politicians want anything to do with
the ethanol mess.

I agree ethanol is a political boondoggle that is net really god for
anyone but the factory farmers and the politicians they fund but it is
not the end of the world. Just buy it and burn it right away. You will
not have any trouble. There are lots of issues with storing it tho.
Even using right away can cause problems with some small engines. It tends
to eat away at some of the rubber type seals. A chain saw comapny had to
recall and change the gas caps as they would swell up and not fit correctly.
A friend has one of the old T model Fords and that ethanol fuel gives it
trouble and ate away some cork that is used in a fuel gauge.
It's more about how long the gas will sit than how full the tank is.
I've never done anything special with my mower gas, and have never had a
problem. But it really only sits unused about 4-5 months at most.
I don't use the snowblower as often, but I do start it up and let it run a
few times a year, even if I'm not using it for snow. So far, no problems.
My chainsaw is a different matter. Whenever possible I like to run the
engine till it is out of gas. But, there have been times I've left gas in
it for a long time without running it. Eventually, the stale gas gummed up
the carburetor and I had to have it serviced.
Last year I started adding fuel stabilizer every time I refill the gas
cans. No problems so far, but will have to see how things work out long
These days I am trying to switch to battery power for equipment that I
don't use often. I have a 56V Ego string trimmer and a 56V Ego leaf blower
that both work great. Plenty of power and run time, and no gas/oil to mix
and store. Our property is too big to go electric for the mower and
chainsaw, otherwise I would choose battery power for those too.

I like to store small engine tanks dry. On things like the chain saw.
I try to run it dry but if I cant, I dump the gas out and use it
somewhere else like my truck. A little oil won't hurt anything in a
10-15 gallon tank of gas. I dump out the premix too if I am not going
to use it right away. I try to only mix what I need.

Empty or full - nothing between.. Empty means fuel cannot absorb
moisture from condensation because there is no fuel. Full because fuel
cannot absorb moisture from condensation because there is no air.
