Claims19
A fuel additive package comprising:
- a detergent including one or more Mannic detergent additives having the structure of Formula II:
- wherein R3 of Formula II is hydrogen or a C1 to C4 alkyl group, R4 of Formula II is a hydrocarbyl group having a molecular weight of about 500 to about 3000, R5 of Formula II is a C1 to C4 alkylene or alkenyl group, and R6 and R7 of Formula II are, independently, hydrogen, a C1 to C12 alkyl group, or a C1 to C4 alkyl amino di(C1-C12 alkyl) group;
- a multi-functional additive comprising a cyclic moiety-containing dicarboxylic acid;
- and
- optionally, an alkoxylated alcohol.
