Abstract
A new lubricant for addition to preferably two-cycle engine fuels is provided. The lubricant may be a solid lubricant in the form of a pellet having a diameter of at least 1 mm., which is readily dispersible when dropped into the fuel. Also, the lubricant of this invention preferably comprises from 25 to 75 percent of a saturated fatty acid having 12 to 22 carbon atoms; (2) from 5 to 25 weight percent of at least one of a polyisobutylene having a molecular weight of at least 800 or a polymerized, unsaturated fatty acid having an average of at least about 24 carbon atoms per polymerized molecule; and (3) from 0 to 50 weight percent of a polybasic ester of a polyol molecule and 2 to 4 fatty acid molecules, each fatty acid molecule having an average of 4 to 22 carbon atoms.
