With more than sixty years of history, the "Speedway Cocktail," as it was originally called, was developed by Joe Lencki, Indy race engine and chasis design engineer and car owner. In 1936, this "cocktail" was under development for use in engines for the Indy 500.

While disassembling race engines for inspection, Lencki found that certain internal parts were scuffed due to a lack of proper lubrication, especially upon start-up. Lencki's Speedway Cocktail solved his internal lubrication problems and created a whole new category of lubrication. Early racing legends eagerly embraced the qualities of Lencki's new micro-lubricant and used it regularly for maximum race engine performance and maximum protection of vital engine parts.

During World War II, Lencki was supervisor in the Dodge plant in Chicago where aircraft engines for large B-29 bombers were constructed. In Chicago, he met Manhattan Project director Enrico Fermi and he perfected his zMAX formula. In 1947, after years of research and proven results on speedways and in aircraft, Lencki finally brought his product to the professional mechanics' market.

The unique ability of zMAX to soak into metal - to literally spread deep into the metal - gives zMAX a protective lubricating quality that cannot be found in any ordinary motor oil or any additive product on the market today. Our advanced scientific manufacturing process reformulates the molecular structure of the base product, creating molecules that are smaller than motor oil and able to soak into metals, providing improved, long-lasting lubrication. In addition, the new molecules have a natural affinity for metal and heat.

zMAX Micro-lubricant protects an engine from the inside out

zMAX, known for years as Lenckite (Linkiteā„¢), cleans, penetrates and protects an engine from the inside out, reducing friction and dispersing carbon deposits, in turn improving horsepower and fuel economy while reducing wear and improving emissions. Functional in all engines and mechanical parts, the Linkite formulation (used in zMAX) is the first pure-lubricant to be approved by the FAA (Federal Aviation Administration) for use in piston engine aircraft.

Today, the zMAX formula is used in hundreds of thousands of automobiles, trucks, motorcycles, off-highway vehicles and airplanes. It has been endorsed by such automotive legends as Carroll Shelby and A.J. Foyt, who testified that zMAX helped him win the 1999 Indy 500 and the 1998 Indy Racing League championship.
