I tried a search, it went like most of my searches,,,, sooooo, is there a shelf life on engine oil?
A year and a half ago, I bought three jugs of Pennzoil Ultra Platinum. I did two oil changes on my 2.7 and have three quarts left in one of the jugs.
I would like to change my factory fill on my 2019 2.7 at 2500 miles, I wondered if it’s okay to use the left over jug to pull one quart from if I pick up a new 5 quart jug?
I have not seen this mentioned anywhere. Thanks!

The oil should be fine.

If it's good in the ground for millions of years, it's good in the bottle for millions of years. That's how I see it.
