The Danbury-based Armor All/STP Products Co. has filed a federal trademark infringement and counterfeiting lawsuit against one of its competitors, claiming intentional misuse of the “High Mileage” phrase and logo.

In a 36-page lawsuit filed July 7 in U.S. District Court in Hartford, Armor All/STP alleges that Arlington, Texas-based TSI Products Inc. began using its marks on some of its “Avalanche” products beginning in April 2016. The lawsuit, which claims violations under the Connecticut Unfair Trade Practices Act and the federal Lanham Act, says the products are commonly used for adding refrigerant to vehicle air conditioners.
