You *are* "just guessing," as you don't know shit about
rancidity. Corn oil and avocado oil are nothing alike.
Corn oil is one of the bad oils as far as rancidity,
whereas avocado oil one of the best. Linoleic acid
(Omega-6) is the stuff that is responsible for most of
the rancidity.

The absolute worst is grape seed oil, followed by
conventional sunflower oil. The best oil that is liquid
at room temperature is macadamia nut oil, but that
is very expensive, and high oleic sunflower oil is
almost as good, for a much lower cost, and is
practically flavorless. Avocado oil is also great, but
tends to be quite a bit pricier than high oleic
sunflower oil. Olive oil is very good too, but is less
neutral in taste. Canola isn't patently bad, like soy
oil--everything labeled vegetable oil in the USA is
soy oil--but many find Canola to have an off taste.
Because of Putin's war, the cost of high oleic
sunflower oil has more than doubled, so for throw
away oil, I've taken to using peanut. It's less than
ideal, but it's a lot cheaper than better oil, and
doesn't taste bad like Canola. For spritzing, I buy
the aerosol avocado oil from ALDI.

It never goes bad, and a can lasts me a good,
long while.
The stuff called vegetable oil (soybean) is not
fit for human consumption, and is best disposed
of by using it to help start charcoal in a chimney,
or to help start campfires. If you have a diesel
vehicle, you could add a cup to the tank at every
fill up until it's gone.
