curious on cracking for oil

[wooden tinsel]

I never really played with it. I do refine oil into light and heavy, but idk how to deal with the byproducts. I was told to do cracking but I have no clue what that necessarily does.

[sudden shadow]

Cracking converts heavier oil into a lighter one.
Heavy oil -> light oil -> petroleum.

Since most of the oil needs are petroleum gas that is pretty nice.

Though some dynamic balancing on when to enable cracking is suggested. This can be achieved with a few tanks, pumps and a bit of circuit wiring to control the pumps

Once I load my save up, and unlock cracking, could you help?

Since this sounds confusing-

And i never used circuits before

Cracking

To use Advanced Oil Processing, all output fractions (Heavy, Light, Gas) must be consumed.
Since the gas is typically the most in demand, converting ("cracking") the heavier fractions into lighter ones is desired.
However, you do want/need the heavier fractions for some things. Circuit controls to the rescue!
Wiki guide

In short: 1) Storage tank with a pump as output 2) Logic wire (either color) connecting the tank and the pump 3) Click pump, set pumping condition / reserve level
It's easy to control the levels and prevent cracking anything but excess

Thats most all of it

Huh.
