Does oil have a shelf life?

Will it last at least 5-10 years prior to putting it into a car?

if you have some quarts in cardboard with the metal lids you may want to use it before it leaks out on the floor. unopened in plastic should last a very long time but as product is improved you may want to add something to boost its performance the stuff we used in the 60's is crud compared to todays mix.

Back in the early '70's I got a bunch of Army surplus oil in quart cans (with a screw on top) and gallon cans. I think I used the last gallon can on rebuilding the engine on my father's '55 Chevy truck in 1975. I still have a quart can left.

I just checked and it was made in June 1966 by R. M. Hollinshead Corp.

In one of the many no more ZDDP content in Oil, early-on panic time posts when we were all scrambling to buy up all of the Shell Rotella "T" Diesel Oil in CI-4 spec. before it was gone, people were talking about hoarding up a 10 years' supply, and someone found tech papers or something to that effect that said that oil has a limited shelf life of something like 5 years or so, if I remember correctly.

It probably boils down to, if you can trust the Oil Co.'s who have been lying to us for years about old car oil and oil/gasoline prices!
