This mod 2x the basic/advance oil processing from the oil refineries (configurable from 1x to 10x: while in the main menu-> settings-> mod settings). This is not for balance but instead just for a faster game with friends. It greatly reduces the requirement to get more oil patches and makes a new world much faster to start

To configure the mod: Go to the main menu (no save/world loaded). Then click Settings, then Mod Settings.
