In general I agree. In part, as you infer, it does depend on the
specific engine. I have never had a problem, but others may. In most cases
if you do either, you should be OK, over winter is not all that long.
However on some engines, it could be a problem and that problem is more
likely related to evaporation than the chemical changes staibilization helps
trouble with running itout of gas for storage, you allways leave some
gas in there that gums up quik,, and you got the air in the tank to
condense droplets into the system all storage season.best way is to
treat gasand leave tank full.lucas
The gas available today seems to be more stable than the stuff back in
the 60's. Leaving gas for 6 months is not likely to cause any problem
(unless it has a chance to evaporate.). I would estimate about 18 months as
a safe period.
However I generally add a little stabilizer at the end of the season and
run it dry. It does not take more than a few minutes. I would not be
worried if I forgot one year and I would expect everything to be OK.
Now my cultivator that was run dry and has not been used for three or
more years is another thing. I expect I will have a real problem getting it
going next time I want it.
What do you hope to gain by putting gas with a stabilizer additive in your
mower and then running it dry? The stabilized gas which might have protected
some carb seals is gone. Wouldn't it be cheaper to just run it dry without
the added stabilizer?hat do you think the stabilizer is doing for you?
Frankly almost nothing. It is just that some years I am a little slow
about that last lawn cut and I don't get around to running it empty. As for
cost I have a couple of containers of stabilizer so the cost is not an issue
so I guess I have just not thought of it.
I prefer draining and running it dry. You don't want the gas that is still
in the carburator to gum up. It won't run very long if you do a good job of
draining the tank. I then pull the plug and squirt a little oil into the
cylinder, and then turn it over a couple times to coat the inside.
Same thing for my snow blower where I consider it even more important to get
all the gas out before a long hot summer.
