C10M 137/10 C10M 129/74
US Classification:
508369, 508382, 508465, 508485
Abstract:
The present invention is directed to green lubricant compositions comprising a base oil and an effective amount of premixed additives that improve wear protection and reduce phosphorus emissions.
The resistance to deposit formation in formulated lubricating oils is enhanced by the addition to the lubricating oil of an additive amount of ionic liquids.

Abstract:
The present invention is directed to a method for controlling soot induced viscosity increase in diesel engines, by using as the diesel engine lubricant an oil formulation comprising a base oil containing about 10 to 80 wt % GTL base stock and/or base oil and/or hydrodewaxed or hydroisomerized/catalytic (or solvent) dewaxed base stock and/or base oil in combination with 20 to 90 wt % conventional Group I petroleum derived base oil, said base oil being further combined with a polymeric viscosity modifier, and to the lubricating oil which effects such control over soot induced viscosity increase.

International Classification:
C10M 135/18 C10M 137/10 C10M 159/18
US Classification:
508363, 508370, 508362
Abstract:
The lubricating oil used to lubricate diesel engines is stabilized against the detrimental degradation effects of biodiesel fuel by the addition to the lubricating oil of an additive concentrate comprising a premix of a first antioxidant, a second antioxidant of a type different from the first and an organometallic compound.
