The Refinery is a machine which converts Oil into Fuel (or, in older versions of Tekkit, Liquid Biomass into Biofuel). Oil can be pumped in with Waterproof Pipes, the Refinery can be filled with buckets or you can place the refinery directly on top of an Oil Fabricator and the oil will be pumped An oil bucket placed in the refinery's input slot will be converted into an empty bucket, and the refinery's oil reserve will fill slightly. The refinery can be powered by placing a Battery into the battery slot or connecting a power source to the top side of the block with aluminum wires. Once powered, the refinery will slowly convert any oil Every tick, the Refinery consumes up to 8 mB of Plant Oil, 8 mB of Ethanol, and 10 Redstone Flux, while generating 16 mB of Biodiesel. It takes 3.125 seconds to make one bucket of Biodiesel. Put another way, the Refinery is able to produce two buckets of Biodiesel every 6.25 seconds.
