I've had a can in the outside garage for around three years. Does it
get stale like gasoline and lose effectiveness, or does it have an

Like anything it can get old, but it does have a long shelf life.
Thanks. Found this:
What is the shelf life of STA-BIL Fuel Stabilizer?
2 years after the bottle has been opened, provided it has been tightly
capped and stored in a cool, dry place.

I wonder how long if not opened?
Actually the info at the site doesn't make sense.
One oz in 2-1/2 gallons gas keeps the gas fresh
for 12 months, and to keep gas for 24 months use
twice as much Sta-bil. But, pure sta-bil is good
for only 24 months after being opened. In other
words, everything goes bad in 24 months. The site
also say that gas can go bad in 60 days.
Anyone who has 3 vehicles and only 2 drivers and
anyone who has a vehicle used only for recreation
in the summer knows that gas does not go bad in
60 days. In fact, for most of us, gas regularly
stays fine for a minimum of 6 months. In a full
tank gas stays fine for at least 12 months and
probably for 24 months. 24 months for gas is
getting iffy, but then sta-bil according to the
site isn't good for more than 24 months either.
Sounds to me like Sta-bil and gas deteriorate at
about the same rate.
24 months? Even 12 months is stretching it.
In the past, my untreated mowers and tractors, shut down in October,
would not start in April unless I added fresh gas to the tank.
The guy who services the chain saw said to change the gas every month
and told me to always use high octane. Maybe 2-cycle engines are
touchier, I dunno.
You might want to think about changing your
service guy! Think about what adding oil to gas
does to the octane.
If your mowers and tractors won't start in April
then you are doing something wrong that has
nothing to do with gasoline deterioration.
