Debunking the Urban Legend of ZDDP
Zinc dialkyl dithiophosphate is a silicate-based lubricating compound developed in the 1940s that was first used in airplane engines. It wasnt long before petroleum companies added it to their motor oils to inhibit wear in automotive engines. It was considered the most effective metal-on-metal anti-wear additive available.

LUBRICANTS WITH ZINC DIALKYL DITHIOPHOSPHATE AND THEIR USE
The lubricating oil composition includes greater than 50 wt. % of a base oil of lubricating viscosity, and an additive composition that includes one or more calcium-containing overbased detergent(s) having a total base number greater than 225 mg KOH/g, and one or more zinc dialkyl dithiophosphate compounds, wherein the one or more zinc dialkyl dithiophosphate compound(s) are derived from a molar ratio of secondary alcohol to primary alcohol of from about 20:100 to about 100:0 and have an
ADDITIVES IN LUBRICATING OILS
Mineral oils react with oxygen of air forming organic acids. The oxidation reaction products cause increase of the oil viscosity, formation of sludge and varnish, corrosion of metallic parts and foaming. Anti-oxidants inhibit the oxidation process of oils. Most of lubricants contain anti-oxidants.
