ABSTRACT:
The lubricity (anti-wear properties) of hydrocarbon fuels, oxygenate fuels or mixtures thereof, particularly diesel or aviation fuels having reduced sulphur and/or aromatic content for compliance with regulatory requirements, is improved by the addition of a phosphorus ester or esters (phosphates and/or phosphites), or a concentrate containing the ester or esters, having a total acid number at least 1.0 mg KOH/g. The additives also improve corrosion inhibition.
