ATI Max-Duty Super F automatic transmission fluid offers lightweight, heavy-duty lubrication for your large-displacement, turbocharged, and high-horsepower engines. This Super F synthetic 30W formula is 100 percent mPOA-based, creating heavier viscosity to experience less thermal breakdown, cooler temperatures, and better converter lockup. Whether you purchase by the quart, gallon or case, ATI Max-Duty Super F automatic transmission fluid will lower the heat and raise the performance of your racing, off-road, or even your monster truck engine to new winning levels.
