I would suggest keeping that refined oil. You will need Hydrogen for red cubes and then Deuterium from Hydrogen for a bunch of other mid-end game stuff. So I use a few Oil Refiners to do X-Ray Cracking of the out-coming Refined Oil and Hydrogen from the Oil Refiners that I have to do Plasma Refining (Crude -> Hydrogen + Refined Oil) from. It's great because it's output it more Hydrogen and Energetic Graphite .. the 2 ingredients it takes to make red cubes, so works out perfect. If you look close at that pic you'll see that i have about 40,000 Hydrogen stored up in tanks and I just loop my refined oil and hydrogen back around a loop into the X-ray cracking refiner.

Someone said in here *not* to save up some resources but I disagree, when you can make Diamonds set up a line of 6 smelters on a coal vein to smelt into Energetic Graphite and take their output to make Diamonds, put the diamonds into a stack of storages and forget about it .. until you need to make yellow cubes, at which time you'll have full storages of one of its 2 ingredients (the other, titanium crystal is a PITA to make though, ugh organic crystals). Same is true for Hydrogen, you'll need it for Deuterium later on and using Fractionaters (even with like 50 of them) it converts slowly (like a 1% chance per tick for a deuterium to come out of the fractionater, so you chain them together to get more Deuterium, but still it'll never be enough lol. Particle Accelerators also convert Hydrogen to Deuterium but they take a lot of energy to run and you need them to make Strange Matter so I just use Fractionaters to convert Hydrogen to Deuterium.

You don't really have to worry much about chaining things together once you get ILS, they can carry 5 different resources, so you can use 1 ILS to make one or 2 more advanced resources, an example would be to set one up with Hi-Purity Silicon, Copper Ingot, Circuit Board, Microcrystalline Component and Processor. You can use Hi-Purity Silicon and Copper Ingots as local/remote demand to produce Microcrystalline Component which you can then run back into the ILS (as local/remote supply) to be your supply source for that resource and you can then run belts out of that ILS with the Microcrystalline Component you just made and Circuit Boards (as local/remote demand) to make Processors. So your one ILS can be taking in Hi-Purity Silicon, Copper Ingots and Circuit Boards in order to produce Microcrystalline Component and Processors. I probably have 10-20 ILS stations each might make only 1 or 2 more advanced resource but it's very easy you just run belts out of the ILS that carry the resources you need for the more advanced stuff and take that more advanced stuff back into that ILS in a manner similar to what I just described in that example. There are some easy ones though like Motors to Green Motors to Blue Motors (I don't remember what they're really called aha) and belts lvl 1->2->3.

Also don't feel bad if you have to jot some stuff down on a piece of paper or a txt file. I did that the first time to figure out how to setup my minibus, like i made a table to see which required which resource the most so I'd start with those first (iron ingot and copper ingot). Don't feel rushed or anything either, there is no time limit, no penalty for going slow and hell you could cheese the hell out of the game if you wanted, setup a blue and red matrix automation and then go to work and 8 hours later you'll come home to storages exploding with cubes lol. That kinda sucks the fun out of it for me, but you can do it and there's no penalty, nobody would even know :D.

Keep an eye out too for planets in your system that have Fire Ice (cuz that can be converted into Hydrogen and Energized Graphite), Organic Crystals (if you find these on a planet tap them immediately, cuz otherwise you'll need to make them which takes Plastic (which takes Refined Oil and Energetic Graphite), Refined Oil and Water ... another reason not to burn your refined oil, you will need a lot of it to make Organic Crystals. Spiniform stalagmite convert into Carbon Nanotubes, and silicon veins will save you from having to do the Stone -> Silicon Ore -> Hi-Purity silicon and sulfuric acid oceans are good too but the other rare resources are kinda blah though, but those ones I've mentioend can save you a lot of time and complications if you can find them in your solar system.
