At 12 hrs I used Aeroshell 100 Mineral Oil in the RV that I had left over from a TOH on the Champ 25 years ago. I figured a few more years on dead dinosaurs would have no significance. When I got the case I ordered this week it had a "Use By July 2020" date on it. Does oil expire? I've put a couple hours on the old oil. Will I fall out of the sky? Hurt my engine? Pardon me if this has been covered before - I confess I didn't check.
