Comparative data are presented on the volume of foam and the stability of foams of aeronautical lubricating oils (new and used) produced at 100 degrees C (212 degrees F) by the air-bubbling method. All of the data were obtained using the same foam meter, by a standard technique and at various rates of air flow.
