So, there's no date printed on the container, but once you open the
bottle it's no good in two years. Sounds to me like they want to have
their cake and eat it too. They don't want retailers returning
outdated unsold product, but they don't want consumers nursing a bottle
for 5 years. Pardon my skepticism.
What's the shelf life of gasoline? It doesn't come with an expiration
date either. A factory sealed container isn't subject to its contents
absorbing moisture, nor oxidizing from from the air. These are the same
factors that cause the degradation of gasoline, only gasoline goes bad
much faster... There was a company a while back selling a "gelled"
emergency gas "can" that you could carry around in your trunk sealed for
an extended period. I'm sure the seal had as much to do with keeping it
fresh as did any additives or modifiers they put in it.
I have an old opened bottle of Stabil in my garage that I haven't gotten around
to diposing. It has turned a nasty darker color and appears to have some solids
floating around in it. I sure wouldn't use it!
Probably about the same age. I don't leave the cap off either, silly.
There are a few ounces remaining. How do you know yours looks and
smells the same as it did five years ago? Hard to believe you have an
accurate memory of what it looked and smelled like 5 years ago, or
that you examined it that closely when you bought it back then.
But... why would you open the new one if there is still product left in the old
one, and you think it never deteriorates? Hmmmm... :^)
I'm not sure about using it in rockets either. There's nothing on the label to
argue for or against it, though!
I never said I think it never deteriorates. I said I was skeptical
about the claim that it has an indefinite shelf life while on the
retailer's shelf, yet when the consumer takes it home and starts to use
it, it's only good for two years.
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.
