Liberal oil is the best oil there is! I recomend everyone buy as much as possible!
It is obtained in a similar way as olive or peanut oil but has steps used in oil and gas production. The liberals are first washed then boiled to soffen their crusty exteriors and remove grime and feces, then they are put into a large hydraulic press and squeezed until their greasy oily innerds are expelled through their pores into a reciptical leading to a heated atomaspheric fractional distiller.this step seporates the useable oils from the greasy sludge. The next step is to run the oil intoa catalytic reformer used to convert the oil-boiling range molecules into higher octane reformate (reformer product). The reformate has higher content of aromatic oils and cyclic hydrocarbons). An important byproduct of a reformer is hydrogen released during the catalyst reaction. The hydrogen is used either in the hydrotreaters or the hydrocracker.
There are also deslters and desulpherizers and a host of other processes.
The long and short of it is that liberal oil is made from liberals and should be used at all costs on/ in everything. Hell use old liberal oil to fertilize your lawn.
Liberal oil is a non renewable resource but there are alternatives when we run out so use as much as you can as fast as you can.
