Does unused motor oil go bad sitting in the plastic bottle? - AllGold - 05-31-2022
I wouldn't think so, but just wanted to be sure.
For background, I just changed the oil on my mower and I've had that bottle for at least five years.

no. not to worry. It's not cooking oil.

It's already million of years old. What's a few more?

Yeah, I wouldn’t think so either. Vegetable oils can undergo oxidation (and become rancid), but that requires aliphatic double bonds, and I don’t think oil for lubrication has any of those.

Yeah.........
In about 100,000,000 years.
Sadly, the plastic bottle is only good for 99.000,000 years. :oldfogey:
