Abstract
Reactions leading to insoluble sediments formation in distillate fuel are accelerated by forcing oxygen into solution in the fuel at pressures of between about 90 and 110 psig and then stressing the fuel under conditions of accelerated storage at temperatures of between about 40.degree. C. to 100.degree. C. The method then makes use of gravimetric determination of the total insolubles formed. The stability of the fuel over a period of time as well as its comparative stability to other fuels can then be predicted from the amount of insolubles formed. The method can be carried out by using a specialized pressure vessel.
