Lubricating oil

What causes the formation of gummy substances (similar to butter) in L-HM68 anti-wear hydraulic oil used in reciprocating compressors? I need an expert to help answer this. (New oil, oil temperature 25 degrees)
Local high temperatures cause the hydraulic oil to oxidize or undergo polymerization reactions, resulting in the formation of gums; such oil has poor antioxidant properties. The high content of unsaturated hydrocarbons in the base oil of hydraulic fluids also makes it prone to the formation of gums
