Volatility Determination of Crankcase Lubricants Using Porous Fiberglass Sheet.

Abstract

Methods for determining the relative volatility of new and used oils are proposed. The procedures involve the measurement of weight losses which occur when oil samples are adsorbed into porous fiberglass sheets and heated. With unused oils, the test is conducted at a higher temperature (155C.); appreciable weight losses are indicative of the presence of more volatile distillates, a factor of considerable importance in the evaluation of motor oils. When the analysis is conducted on used oil at a more moderate temperature (75C.), a correlation exists between weight loss and gasoline dilution. The methods are easy to conduct and consonant to the routine analysis of multiple samples. (Author)
