Enhanced GDI Performance

HiTEC® 65531 demonstrates exceptional performance in gasoline direct injection engines. Afton Chemical measured the performance of a one-tank clean-up of HiTEC® 65531 in a GM GDI LHU engine by running the engine in E0 fuel for 66 hours (dirty-up phase) and then treating the fuel with HiTEC® 65531 (clean-up phase). After being treated with HiTEC® 65531, the GDI engine ran for 8 hours, and the gasoline direct injectors saw an 85% improvement in injector fouling.
