The Lubrication Properties of Gasoline Fuels

Liquid hydrocarbon- based fuels must possess a modicum of lubricating ability to be able to protect pumps and related fuel supply equipment from wear. The lubricating ability of fuels, because of their very low viscosity, stems largely from boundary film forming properties. This paper reviews the lubricity of gasoline and describes the service problems that may result from increasing constrains on gasoline composition and from the solutions devised to meet them.
