Fluorinated ZDDP improves engine mileage, reduces engine wear, preserves catalytic converters
This technology takes ZDDP -- an anti-wear oil additive in use for over 75 years -- and enhances it by adding fluorine to the chemical backbone. The resulting new molecule testably improves engine fuel economy by 3%, reduces engine wear from that available with conventional ZDDP, and perhaps most important, contains from 100-250 ppm of phosphorus (about a third the current amount in oils) thus prolonging the life of catalytic converters. The fluorine in the molecular backbone makes ZDDP more reactive and more polar, allowing the use of even smaller amounts of the additive than is current practice. The new additive has passed a series of key engineering tests, such as the Sequence 6D fuel economy test for rings and cylinders, and has shown a 3% improvement in fuel economy in formulations with 250ppm of phosphorus. Sequence 3D tests are planned. Toxicology tests show no difference from ZDDP. The additive is a liquid, and so presents no suspension issues. In grease and in similar lubrication applications, the new molecule is effective at both low-load/high-speed applications and at high-load applications (the grease additive moly dioxide is abrasive at low loads). Fluorinated ZDDP has application in all internal combustion engines; in gasoline, diesel, and natural gas generators; in transmissions and differentials; and in grease and lubrication applications (such as wheel bearings, CV joints, journal boxes, and automated machinery).
