    Abstract: A fuel composition, a lubricant composition, and methods for reducing friction or wear of moving parts. The fuel composition includes gasoline and from about 10 to about 500 ppm by weight of a dialkylaminoalkanol of the formula R1(R2)NCH2CH(R3)R4. The lubricant composition includes base oil of lubricating viscosity and from about 0.05 to about 5.0 weight percent of a dialkylaminoalkanol of the formula R1(R2)NCH2CH(R3)R4. In the above formulas wherein R1 is an alkyl group or a hydroxy alkyl group containing from 8 to 50 carbon atoms; R2 is an alkyl group containing from 1 to 4 carbon atoms; R3 is selected from H and OH; and R4 is selected from H, an alkyl group containing from 1 to 4 carbon atoms, and CH2OH and wherein at least one of R3 and R4 contains a hydroxyl group and provided that when R1 is a hydroxyalkyl group, R3 is OH and R4 is CH2OH.

    Abstract: Methods for improving the injector performance, unsticking fuel injectors, and reducing an amount of alkali metal carboxylate deposits on internal components of fuel injectors. The method includes operating the diesel engine on a fuel composition comprising a major amount of diesel fuel and from about 45 to about 550 ppm by weight based on a total weight of fuel composition of a fuel additive consisting essentially of a compound of the formula wherein R is an alkyl or alkenyl group containing from 20 to 170 carbon atoms. The additive has a total acid number (TAN) ranging from about 50 to about 290 mg KOH/g. Fuel injectors of the fuel injected diesel engine have an average injector hole diameter of less than 160 μm and an average smallest clearance between injector needle and injector barrel/casing of less than about 10 μm.
