    Shelf life of 2 stroke oil?

    I have used oil that I have stored for up to 3 years with no issue. Don't think oil should go bad unless it something like a decade old. Then you can put it in eBay as a collectors item.

    I`m going to say (assume) these un opened gallon jugs are more than 3 years old.

    I opened one of the jugs last year, or the year before and have used it by adding a few ounces here or there when needing to add make up oil. it mixes fine with Interceptor.

    5 years in warm storage conditions, 2 years in cold. (additives come out of solution)

    They very well could be 5 years or more. They were stored in a shed with hot summers and cold winters before I bought/received them through a package deal. and in my possession for 2+ years.
    I have 2 remaining unopened gallons, and will just use them in the lawn equip if I don`t toss them out... the other gallon was used for lube for the RV cavity only.

    I'm working on a jet ski that has sat for a long period of time and the oil has taken on a jelly like consistency.

    def not jelly in the bottle. Looks good and smells like it should XPS blend...

    First time I have read a specific timeline for 2-stroke oil longevity. Interesting.

    Do you have a reference or perhaps a link for that info?

    Gosh. If it was "sealed" with the original aluminum seal and then capped, I would have thought many many years. But who keeps them that long any way? HA!
