Get More Fuel Lubricity with Premium Dieselex-4
Premium Dieselex-4 features enhanced lubricity chemistry. In lab and field tests, Premium Dieselex-4 has been shown to provide the lubricity needed to maximize diesel engine performance while minimizing engine friction.
Researchers measure fuel lubricity based on the wear scar created by the fuel. U.S. government regulations require that diesel fuel create a wear scar no greater than 520 micrometers. CountryMark holds their fuel to a higher standard. By optimizing fuel lubricity, Premium Dieselex-4 has been proven to leave behind a wear scar of only 460 micrometers.
By optimizing fuel lubricity, Premium Dieselex-4 creates less wear and tear on injectors and injector pumps, and this leads to less downtime and extended fuel system life.
