    Standard Treat Rate: 1 oz (30ml) of AR6500 Diesel Treatment per 10 gallons of diesel.

    Power Boost: 2 oz (60ml) per 10 gallons of diesel. For best results use Power Boost dose in first tank of fuel.

    AR6300 Winter Diesel Treatment is added to every tank of diesel to boost performance, improve fuel lubricity, protect your fuel system and protect against gelling in cold weather.

    Standard Treat Rate: 1.5 oz of AR6300 per 10 gallons of diesel (reduces CFPP to -16ºF)

    Power Boost: 3 oz per 10 gallons (reduces CFPP to -44ºF)

    When no anti-gel protection is needed, use AR6500 Diesel Treatment.

    Treat Rate: For all Power Strokes, use 16 oz of AR9100 every oil change. For engines, limited slip differentials and motorcylces, use 1.2 oz of AR9100 per quart of conventional or synthetic oil.

    Diesel Fuel System Kit

    The Diesel Fuel System Kit is designed to clean, restore and boost your diesel engine's fuel system. Featuring AR6400-D, this kit effectively removes stubborn deposits, helping to recover lost power and fuel efficiency. To complete the restoration, AR6500 Diesel Treatment maximizes performance by boosting cetane, improving MPG and enhancing lubricity to protect key fuel system components.

    Unlike other diesel treatments, the Diesel Fuel System Kit removes carbon from the turbo and DPF, leading to reduced regens, restored efficiency and maximum power.

    AR6500 Diesel Treatment - Two Pack

    AR6500 is the only treatment to clean, restore and boost the entire fuel system with chemistry that removes deposits and build-up from the turbo and DPF, resulting in reduced regen frequency, improved response and increased fuel economy.

    As AR6500 continuously cleans the fuel system, the formulation also provides a strong cetane boost for improved combustion and enhanced lubricity to protect key fuel system components.

    The Two Pack treats up to 800 gallons of diesel, working out at less then 9¢ per gallon treated in the Black Friday Sale!

    Ultimate Winter Diesel Kit

    Bringing all the benefits of the Ultimate Diesel Kit plus anti-gel protection down to -44ºF, this is the must-have kit for diesel owners in colder climates.

    AR6300 prevents fuel from gelling in freezing temperatures to ensure your diesel runs smoothly on the coldest days. Avoid trouble starting the engine, poor acceleration and sluggish performance with the Ultimate Winter Diesel Kit.

    AR6300 Winter Diesel Treatment - Two Pack

    Unlike other cold weather treatments, AR6300 Winter Diesel Treatment not only provides anti-gel protection, it also enhances lubricity, increases cetane, and continuously cleans injectors, turbos and DPFs. This is the ONLY fuel additive you need to ensure your diesel powers through the cold weather.

    Good results 3 weeks in

    SO far we are 1/2 way through 2 of the 3 bottles ordered on 2 different trucks and mileage is significantly improved on one and a little on the other with both units using less DEF fluid overall. Looking forward to putting another unit on it and ordering more for the other trucks as well. This was an experiment that has definitely paid off.

    Temp was 10F this morning and my truck fired right up without being plugged in so I am happy with that. Will give it some more time, still running the first tank full through.
