Claims6
A fuel composition comprising:
- a base fuel wherein the base fuel is a blend of gasoline and ethanol wherein the base fuel comprises from 10% by volume to 85% by volume of ethanol;;
- from 25 ppm to 100 ppm by weight of a lubricity additive, based on the total weight of the fuel composition;
- wherein the lubricity additive consists of 1-Lauroyl-rac-glycerol and wherein the lubricity additive is soluble in the fuel.
A method for improving lubricity of a fuel composition, providing a base fuel wherein the base fuel is a blend of gasoline and ethanol wherein the base fuel comprises from 10% by volume to 85% by volume of ethanol;
- adding from 5 ppm to 100 ppm by weight, based on the total weight of the fuel composition, of a lubricity additive to the base fuel to produce the fuel composition;
- wherein the lubricity additive consists of 1-Lauroyl-rac-glycerol and wherein the lubricity additive is soluble in the fuel.
A method for improving fuel performance of a direct injection engine the method comprising,
- fueling the direct injection engine with a fuel composition comprising a base fuel wherein the base fuel is a blend of gasoline and ethanol wherein the base fuel comprises from 10% by volume to 85% by volume of ethanol;
- and from 5 ppm to 100 ppm by weight of a lubricity additive, based on the total weight of the fuel composition;
- and
- operating the direct injection engine;
- wherein the lubricity additive consists of 1-Lauroyl-rac-glycerol and wherein the lubricity additive is soluble in the fuel.
