Abstract
A fuel composition of improved lubricity comprises a lubricity-increasing amount of a lubricity aid dissolved in low sulfur diesel fuel and spark ignition fuels. The lubricity aid is an alkanolamide of a fatty acid, an alkanolamide of a modified fatty acid or a mixture thereof. If the lubricity aid is other than an alkanolamide of an aryl-substituted fatty acid, the composition further necessarily comprises a haze-inhibiting amount of a dehazer. The lubricity of such fuels may be enhanced without acceptably increasing the tendency of the fuel to become hazy upon contact with water.
