You don't need tons of grease, you just need the correct technique.

To make fried eggs in a non-nonstick pan? Of course you do. You need enough so it doesn't stick. There no technique that can rescue egg stuck to a pan.

The thing is, any more oil than that just stays in the pan. Fried eggs don't absorb oil.

So put plenty of oil in the pan, because it won't wind up on your plate. There's zero reason to skimp, otherwise you'll just get eggs that stick.
