Another day another stupid question

Have you guys ever wondered why you can’t change the oil in your car with cooking oil instead of engine oil? I mean what could possibly go wrong what would happen if you changed your car’s oil with vegetable oil instead of regular 5w30 engine oil?

I had to decline someone an engine replacement a few months ago because they used fucking cooking oil on their fucking big-ass diesel truck! The fucking stupidity of people!

@Dad34 Well either they purchased a new engine for around 15,000 or they got their of their Truck. I don't know I closed their case out.
