In the early 1930's, Indy race engine and chassis design engineer Joe Lencki discovered the need for special lubrication in engines. While disassembling Indy 500 race engines for inspection, he found internal parts, especially cams, were scuffed due to a lack of proper lubrication, especially during start-up.

In 1936, Lencki developed "Speedway Cocktail" (later named zMAX Micro-lubricant) to help solve internal lubrication problems, creating a whole new category of lubrication. Early racing legends such as George Bignotti, Tony Bettenhausen and Johnny Parsons, Sr. embraced this new micro-lubricant that literally soaked into metal, using it regularly for maximum performance and protection of vital race 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. While in Chicago, he met Manhattan Project director Enrico Fermi and with Fermi's advice, Lencki perfected his soon-to-be-called "zMAX Micro-lubricant®" formula. In 1947, after years of research and proven results in race engines and aircraft, Lencki introduced zMAX to the professional mechanics' market.

zMAX Micro-lubricant, known for years as Lenckite (Linkite™), cleans, penetrates and protects an engine from the inside out. 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 known as AVBLEND.

zMAX Micro-lubricant is used in thousands of automobiles, trucks, motorcycles, outdoor equipment and airplanes, and has been endorsed by the late automotive legend and car builder, Carroll Shelby, who used zMAX in every car he built.
