I can judge without trying. That engine is gonna do some funky things.
But... it'll most work, right?
Hear me out: given a choice between running the engine completely dry of oil, and using vegetable oil, which would be worse?
The vegetable oil is going to gum things up. I guess you're looking at an engine replacement either way.
Given a choice between being impaled on a rusty fence and being shot, which would be worse?
Yup.
May the machine gods have pity on your bearings.
@Kecessa pointed us to a video of Project Farm checking it, and it turns out soy bean vegetable oil worked great, except in very cold conditions:

So, not so dumb. As long as she gets an oil change well before winter, she, and the engine, will probably be just fine.
A lawnmower and a car use very different oils and running something for a short time is very different than under loads for extended periods of time.
It is dumb to use cooking oils in a car engine.
Project farm tried it!

That's freaking awesome! Looks like what she was doing wasn't so silly after all!
This one trick the Big Engine Oil companies don't want you to know about!
Seriously though, what would happen? Oil is basically just for lubrication, right? Vegetable oil is obviously completely different from regular oil, but I don't know, how and when it would cause problems.
What you call as just, actually is a quite essential task.
The vegetable oil would not cause instantaneous damage and is definitely better than no oil. However, as it does not fulfil the specified requirements of the engine and also ages faster, I don't recommend driving the car for a much longer distance than to the next car workshop to do a complete oil change and service.
To add: mixing in this oil is almost guaranteed to cause all the suspended shit in your oil to drop out. The viscosity of the oil when it is cold is lower than that of the engine oil when warm. Cooking oil burns at a fairly low temp. Like https://lemmy.ca/u/Successful_Try543@feddit.org said it would only really get you to the shop. Your rings would scrape, your bearings would be at a high risk of metal to metal contact, the quickened aging process would start right away and excess carbon would be a sudden issue. The engine would not be able to dispose of its heat very well, due to issues with the oil, and be at risk of overheating. Depending on how the cooling system is set up, it is at a higher risk of failure that would put water and oil into contact, which isn't good. Also, it could cause varnishing in certain internal oil galleries, which would cause a series of issues and failures.
But how delicious would your engine smell?
For la bella macchina only extra vergine is good enough.
