PURPOSE of the investigation reported in this paper was to find a suitable laboratory test method for the stability of aircraft-engine oils.Three types of laboratory methods were chosen, and data were obtained on two of them using 22 aviation oils. The two methods were (1) heating the oil with the surface exposed to the air but without aeration, and (2) heating the oil under aerating conditions. Results were compared with engine data on the same 22 oils covering 30 hr. of operation in each case at cruising power with a Pratt & Whitney Hornet engine. Three conclusions are drawn:
