Home made mayo is shelf stable. PH should be down around three. It’s the grocery brands that try to smooth out the tang and increase the PH that makes it need refrigeration. It sounds insane that egg yolks and oil don’t go bad on the counter if you add lemon juice but that’s about the extent of it.
That’s not to say it doesn’t degrade much faster and honestly, mayo need to be cold or it just feels like sandwich grease :)
Straight seed oil can oxidize. If you ever open canola and instead of musty corn it sells like freeze dry, that’s “bad” Unsaturated and to a lesser extent mono-unsaturated fats do like to pick up hitchhikers in those chains with holes. But like Peanut, and Rapeseed, seem to last forever.

i’ve never actually seen oil turn bad. and that’s after i keep them without refrigeration for months.
