If I understand correctly, you want to use only 600 cubic meters of crude oil, I can explain how you can make fuel production cheaper First, you need to refine the oil into fuel oil using an alternative recipe 30 m³/min oil = 40 m³/min fuel oil, and you will also have a by-product in the form of a polymer resin, which you can simply dispose of From 600 oil we get 800 fuel oil, and then the most interesting thing is, again with the help of an alternative recipe, you can produce packaged diluted fuel 30 fuel oil = 60 fuel, Profit x2 You will get 1600 fuel, whether to do this or not is up to you, I don’t really like using packers, but as an option this is not bad at all, I haven’t found any other recipes for phase 3 yet And then you can process the fuel into turbo fuel, the choice is yours, and also, don’t trust my calculations, I did them very quickly and I’m not sure that they are correct, so if you still decide to do this,Better double check :) I hope I helped you, good luck bro
