Afton Chemical Corporation, a subsidiary of NewMarket, announced the launch of its HiTEC® 65522 Gasoline Performance Additive (GPA) series. This new series has received approval for use in TOP TIER+™ gasoline, an updated standard designed for modern engine technology.
The HiTEC® 65522 series is specifically formulated to address critical issues in Gasoline Direct Injection (GDI) engines, which are now prevalent in 74% of new vehicles in North America. These issues include injector deposit control and protection against stochastic pre-ignition (SPI), both of which can impact engine efficiency and longevity.
The new TOP TIER+™ standard, revision G, published in early January, incorporates two new test methods using a GM LHU engine to evaluate injector deposit control and SPI protection. Afton Chemical's new additive series aims to provide superior deposit control and maintain optimal engine performance, aligning with these stringent new requirements.
