Cooking oil bottles have pretty large pour spouts that can be hard to control. One unpredictable move, and you've added way too much oil to a dish. To remedy this, just poke holes in the foil seal.
If you want more control when you're pouring cooking oil, syrup or any other liquid ingredient, use a fork to poke small holes in the foil seal when you first open the bottle. This way, the liquid doesn't come out so fast.
Of course, you can always pour the oil into a measuring cup and then transfer to the dish. Sometimes, I'll pour a small amount into the lid and then carefully add it that way. But this is a much more convenient solution that tackles the problem at the source.
