He may know oil, but he has very little idea of what happens inside a
gasoline engine that puts in the oil what he finds there.

Basically, he can tell you what's in the oil, but he can't tell you why
it's there. He may think he can, but he can't.

If I change something I can see the effects, if any of the change.

For some reason, it doesn't work with the Supra...
