Abstract
We closely studied the action mechanism and deterioration mechanism of ZDTP (zinc dialkyldithiophosphate), used as an essential additive in engine oils for over half a century, and determined that the sulfur in ZDTP was hampering efforts to improve oil life. With this in mind, we developed a completely new engine oil blended with ZP (zinc dialkylphosphate), in which oxygen replaces the sulfur in ZDTP, and conducted engine tests. The tests confirmed that the newly developed oil provides long service life that cannot be attained with conventional oil formulated with ZDTP.
