Old Oil

Alpine650 · 09-12-2023, 04:30 PM

I was cleaning up in the basement and found 2 quarts of Penzoil 5W-30. The price tag on the cap was $1.59. Two questions, what year(s) do you think it could be from and is it still good to use?

If it were synthetic, my guess is it would be fine. That being said, I would just use it for my lawn mower.

This calls for a google search.

"Does motor oil go bad if unused" is the phrase I typed into a google search and these two links were at the top of the results list:
