This paper presents the results of an evaluation of the significance and utility of several laboratory derived expressions for defining volatility characteristics of motor fuel as related to hot weather performance problems. This evaluation showed MRvp, a Reid type vapor pressure measured at a vapor/liquid ratio of 25 and at 130 F, to be a simple, significant volatility expression having the following advantages: good correlation with vapor forming characteristics of fuels; superior reproducibility and repeatability; adaptability to conventional blending calculation methods; convenient means for direct interpretation of road test data and for comparison of fuels of varying composition and characteristics.
