Some vegetable oil oxidizes much faster than some other. Sunflower oil oxidizes rather quickly, olive oil I haven't noticed oxidizing yet.

- throwaway984393 5y agoAccording to this chart, Olive oil has 12 times more oxidative stability than Sunflower oil! Coconut oil has the highest oxidative stability due to its 92% saturated fat content: https://olivewellnessinstitute.org/resource/showdown-what-is-the-best-oil-for-cooking/ https://olivewellnessinstitute.org/resource/showdown-what-is...
- ahartmetz 5y agoThese tests seem to be done at elevated temperature or some other accelerated method, because no oil oxidizes noticeably in mere hours. My experience at low temperatures is that the difference is much bigger than in that test. A thin layer of sunflower oil takes a week or two to turn into hard to remove sticky goo, olive oil... basically doesn't seem to do that at all.

- hellbannedguy 5y agoI cut/thread pipe with Olive oil. I also use in on material in my watch lathe. I started using it because I ran out if cutting fluid, and noticed no difference. (It seems like I'm always being told to use this oil, or cleaner, when I'm working on a project. Before paying for the brand name, I always look up the MSDS on the product. Many products can be made at home with experimenting.)
