Product Details
✓EASY USE AT EVERY FILL-UP: Add directly to the fuel tank at each fill-up. The long neck and measuring chamber make treating fuel simple. One 40 oz bottle treats up to 400 gallons
✓FOR ALL DIESEL ENGINES: Suitable for use in all diesel vehicles and equipment - light-duty, heavy-duty, pickup, SUV, van, RV, etc. (including modern HPCR systems)
✓IMPROVES LUBRICITY (ASTM D6079): Tested to improve lubricity by 43% to help protect fuel system components, including wear-sensitive parts like the CP4 pump
✓BOOSTS CETANE UP TO +8: Raises cetane up to 8 points for faster ignition, smoother combustion, and improved drivability; many engines run best around 48–50 while pump diesel is often 40–45
✓CLEANS INJECTORS: AR6500's detergent package removes injector deposits and restores spray patterns for improved atomization, supporting better performance and fuel economy
✓SUPPORTS DPF & REDUCES REGENS: Targets deposit formation to help keep the DPF clean and reduce regeneration frequency – restores performance, fuel economy, and extends DPF lifespan
✓KEEPS TURBO CLEAN: Helps reduce fuel soot and deposit formation that impacts turbo response, restoring boost and smoother acceleration
