ASSESSMENT OF STORAGE STABILITY ADDITIVES FOR NAVAL DISTILLATE FUEL

This paper assesses the effectiveness of the stability additives allowed by the current U.S. military specification and that of several selected stability additives used in commercial practice. five of the six currently allowed additives were included in this evaluation as were five proprietary products used in diesel fuels and heating oils. This work emphasised tests on five selected fuels which exhibited poor or marginal stability behaviour. The results of accelerated storage stability tests run under a number of test conditions with temperature being the main variable are presented. Three laboratories performed stability tests at temperatures from 43 to 95 degrees C. In addition, light scattering intensity measurements were made in conjunction with the gravimetric measurements. Finally the effect of additives on selected fuel properties which might be altered by addition of the tested additives was determined.
