MASS MARKETED OIL manufacturers constantly re-engineer their products for the latest engine applications, which has left older vehicle's engines without the essential detergents and anti-wear agents they need to operate properly. With ever tightening EPA regulations and catalytic converter damage related to zinc, ZDDP has been drastically reduced in modern day oils. ZDDP is an essential friction reducing agent for all vehicles that utilize flat tappet camshafts. Use of an oil without ZDDP in flat tappet cam engines greatly increases the probablility of premature wear, engine seizure, and even complete engine failure.

DIESEL OIL, up until recently, contained high levels of ZDDP. This is no longer true! The EPA now requires low emission diesel engines. One emission source is zinc phosphates from consumed/burned diesel oil. Hence it has been removed from diesel oil. Today's diesel oil also has high levels of detergents. These detergents act in opposition to the extreme pressure additives that flat tappet camshaft gasoline engines require and can cause excessive wear.

RACING OIL is offen used in street vehicles, but it is not engineered for extended mileage use. it has low levels of needed detergents and some have high levels of paraffin-based friction reducing additives that can actually lead to deposits being built up in street driven engines.

ADDITIVES seldom disclose all the compounds they contain. Teflon can leave deposits and clog passages, solvents can change the oil itself and reduce its lubricity, Chlorinated Paraffins chemically change under heat and pressure into hydrochloric acid and corrode the metal in your engine. Others use high levels of ZDDP in an additive form to be dropped in your favourite oil which often do not blend well with the oil or breakdown and introduce harmful solid particles to your engines lubrication system. Too much ZDDP can actually increase engine running temperatures.
