    Does Outboard Motor Oil Have A Shelf Life ??

    Yesterday afternoon I found a gallon of unopened Johnson Outboard motor oil that was given to me by the dealer when when I bought my boat in 2004. It's been sitting in the building covered up by some other stuff and I had honestly forgot about it.

    I hate to just dispose of it because the stuff costs so darn much. Is there a shelf life and would it be safe to use ??

    I will defer to one of the mods but me personally, if the cap is still sealed, I would shake it good and use it. I don't think there is anything in it that will separate or go bad. but that's just me...

    My remember my dad had cases of johnson oil in tin cans for years after they got out of the boat business. That man must've literelly had a truckload of that oil stashed somewhere.

    I'm thinking the same as to how it could go bad. First thought was that like gas it could go stale over time but I suppose that is like comparing apples to oranges

    Gas goes bad because the Octane breaks down if untreated. Oil doesn't go bad.
