Oil longevity

Does oil have a shelf life? I just mixed the last of a oil bottle bought from 2011. Am I ok to run the jon boat?

I was told by a vendor 5 years is the shelf limit on oil. If you’ve had some oil sitting up for a long time, make sure you shake it up real good. There is a chance of some additives “settling” at the bottom.

I’ve got some Amsoil that is 20 years old that I still use in my chainsaw.

2011… your in good shape as long as the container was sealed.

no problem to use oil from 2011
