  • FOR ALL DIESEL ENGINES: Suitable for all diesel vehicles and equipment, including modern HPCR systems
  • CLEANS INJECTORS & RESTORES RESPONSE: Removes injector deposits and restores spray patterns for smoother running, improved response, and more efficient combustion
  • IMPROVES LUBRICITY (ASTM D6079): AR6500 is tested to improve lubricity by 43% to protect fuel system components, including wear-sensitive parts like the CP4 pump
  • BOOSTS CETANE UP TO +8: AR6500 raises cetane up to 8 points for faster ignition, smoother combustion, and improved drivability
  • SUPPORTS DPF & REDUCES REGENS: Targets deposit formation to help keep the DPF clean and reduce regeneration frequency - supporting performance and fuel economy
