I have a box of Stanadyne that is four years old. Is it still good?

Not sure


Why don't you call them up and ask them. Web site is www.Stanadyne.com (http://www.Stanadyne.com) They must have a contact phone number on the site.

Should ask the manufacture, but I would think if it's never been open it should be good as new.

There is a foil seal under the cap - so I would guess that it should be okay. Call the mfg to make sure and let us know the outcome. My local Stanadyne rep told me it also acts as a fuel "stabilizer" - so I would hope it lasts awhile.

FWIW, I bought a 5 Gal pail (Stanadyne Performance Formula) about 3 years ago when I still had my 98 6.5 and I would guess it had been sitting there for a while before I bought it. I have about a half gallon left and it still works the same as new.. I can 't tell any difference...
