Cycle oil

Small oil application device for Singer sewing machines

Cycle oil is a light lubricating oil suited for use on bicycles and similar devices.^[citation needed] It is a liquid residue produced in the petroleum industry when catalytic cracking is employed to convert heavy hydrocarbon fractions remaining from earlier stages of crude oil refining into more valuable lighter products.[1]^[unreliable source?]

Catalytic cracking produces petrol (gasoline), liquid petroleum gas (LPG), unsaturated olefin compounds, cracked gas oils, cycle oil, light gases and a solid coke residue. Cycle oil may be processed further to break it down into more useful products; in particular it may be mixed with heavier products and put through the refining process again (recycled).[2]
