The Bureau of Mines developed a rapid test method for predicting the stability of motor gasoline during long-term storage. The amounts of gum and inorganic residue formed in 13 gasolines during a 16-hour oven test at 200F were compared with the amounts formed in the same gasolines stored at 110F. By use of a modified Arrhenius equation, the 110F storage time can be extrapolated to equivalent time at any temperature below 110F. By combining the stability prediction method with the mathematical extrapolation, the storage performance of motor gasoline for extended periods can be estimated at any temperature up to 110F.
