Location & detailsEdit
The oil spawns in small pools, of about 12 blocks or so. The oil greatly resembles water, in physics and opacity.
Once an oil source is found you need to have a Bucket . Stand within a source block of oil and hold Right mouse button, the block of oil is used almost instantly. Unfortunately the oil block isn’t destroyed, but simply lowered by about 1/3 and right clicking in the same source block will not get more oil, thus leaving some confusion of how much oil is actually there. Once the Bucket is full you can use a Refinery, the oil turns into fuel, which can then be used in the rocket.
