All in one Oil refinery which produces everything with regulated logic for heavy and light oil cracking, Also included are meters for each type of liquid. Yellow meter on the right is redundant, its just meant to be played around with using the Constant combinator.
This design is meant for solid fuel heavy plays, if you dont use alot of solid fuel (for trains or rockets) its gonna be harder to balance this refinery
Regarding meters
1 Red = 10k or less
2 red = less than 30k
2 Yellow = 39k or less
3 Yellow = 49k or less
3 blue = 50k - 60k
4 blue = 60k - 70k
5 blue = 70k - 80k
5 green = 80k - 90k
6 Green 90k - 100k (full tank, crude oil container holds 1Mil)
EDIT: Fix some issues with pipe on solid fuel side, added lights for solid fuel production, improved balancing on logic.
EDIT 2 (should be final): Re-balanced cracking, added more lights (because who dosent like a light show) added emergency cracking (activates ALL crackers of its type) when petroleum or light oil drops below 10k, change meters to a better type, Balanced production line (plastics, explosives and batteries)
