  • Conductivity-improving additives for fuel
    Patent number: 9574150
    Abstract: A fuel additive composition, fuel comprising said additive, and methods of use thereof are provided. The fuel additive composition comprises a synergistic combination of a hydrocarbyl-substituted succinimide dispersant and a compound of the following formula: and tautomers and enantiomers thereof, wherein R3 is a hydrocarbyl group having a number average molecular weight ranging from about 100 to about 5000, and wherein the weight ratio of (a) to (b) ranges from about 5:1 to about 1:5. The fuel additive composition is present in fuel in an amount sufficient to improve the conductivity properties of the fuel.
