Outboard Oil Shelf Life

[ant]

I bought four gallons of outboard oil when the local dealer had a 50% off sale. Two gallons are in the manufacturer's sealed gallon container, and two gallons are from the dealer's bulk oil tank.

What is the expected shelf life for an outboard oil?

It it decent product, with the dispersants that good oils have, and ashless detergents, its good for years.
