Archoil AR6500 Diesel Treatment (25 oz) - Treats 250 Gallons - Additive for All Diesel Vehicles

AR6500's detergents and lubricants have been engineered to clean, lubricate and protect your fuel system including injectors, pumps, lines and tank in all systems including the latest high pressure common-rail injection fuel systems. AR6500 also incorporates Archoil's proven combustion modifier technology and a strong cetane boost to increase power and response and reduce soot and carbon build-up in turbos, DPF and EGR components.

• ‌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 25 oz bottle treats up to 250 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
