Beschreibung
Zusammenfassung:	The purpose of the present invention is to provide: a refrigerator oil (lubrication composition) that improves the wear resistance of an Oldham's link during a high oil temperature/low speed operation; and a method for producing the same. This method for producing a lubrication composition includes: a selection step in which a selection is made of a lubrication reagent, as an additive for improving lubrication characteristics, having a decomposition start temperature that is in a temperature range of 70-90°C, the decomposition start temperature being the temperature at which the change in thermogravity is 0.675-0.825%; and a blending step in which the selected lubrication reagent is blended, in the amount of 1-5 wt%, into a base oil.
