About Frantz Filters

Established in 1953 by John Frantz, the Frantz Filter Company became a mainstay product and process for cleaning automotive oil worldwide. Over the years, Frantz Filters has stood for innovation in the oil filtration process.

In 2014, Frantz Filters was purchased by Lubrication Specialties, Inc. (LSI), the makers of Hot Shot’s Secret products which focuses on problem specific solutions for diesel and petrol engines. Frantz Filters is a strategic fit with the LSI line up of companies. The same powered by science approach taken in developing Hot Shot’s Secret products has been applied to reinventing the Frantz Filter media to create an optimal filtration process offered exclusively through LSI.
