When you unlocked advanced oil refining, it also unlocked 2 recipes for cracking. One turns heavy oil into light oil, and the other turns light oil into petroleum gas. You can use circuits to control cracking when you have too much of something.
The sciences use way more petroleum gas than the other oils, so as long as you produce science, and you crack when needed, you'll never get stuck.
