  • Publication number: 20170037332
    Abstract: The invention relates to the use, in a hydrocarbon distillate with a boiling temperature of between 150 and 450° C. and a crystallization onset temperature as measured by Differential Calorimetric Analysis of greater than or equal to ?50° C., preferably of ?5° C. to +10° C., of a homopolymer obtained from an olefinic ester of carboxylic acid of 3 to 12 carbon atoms and from a fatty alcohol containing a chain of more than 16 carbon atoms and optionally an olefinic double bond, as a compound for revealing the efficiency of filterability additives based on copolymer and/or terpolymers of ethylene and of vinyl ester of a carboxylic acid of 3 to 12 carbon atoms, and of a monoalcohol containing 1 to 10 carbon atoms. The invention is also directed to an additive composition comprising a conventional hydrocarbon filterability additive in combination with an efficiency reveal additive, and also to the combustion fuels, motor fuel and oil fuel that comprise these additive combinations.
