Diesel engine technology is changing. And so must heavy duty engine oil. As engine manufacturers engineer cleaner and more fuel-efficient diesel engines, they need engine oils that perform under more severe operating conditions. The American Petroleum Institute introduced a new diesel engine oil specification, broken into two categories, CK-4 and FA-4.
Suprex Gold ESP has been upgraded to not only meet these changing specifications but exceed them. Your fleet can expect more durability and enhanced protection through Suprex Gold ESP at viscosity grades that improve fuel economy. CK-4 oils will be a direct replacement for the current oil used, today. FS is excited to also introduce an FA-4 oil, Suprex Gold HFE 10W-30, to ensure full coverage if your fleet requires this oil type or if you're looking to capture the most on fuel savings.
When you rely on your equipment, rely on Suprex Gold ESP and Suprex Gold HFE. Meeting API industry performance standards is not enough. Suprex Gold ESP has always been formulated to exceed those standards and is now even more robust. Improved operating performance, reduced downtime and lower maintenance costs make Suprex Gold ESP and Suprex Gold HFE the best values in heavy duty engine oil.
