    Royal Purple Max-Clean Fuel System Cleaner & Stabilizer
    Royal Purple's New Max-Clean is a state-of-the-art high performance synthetic fuel system cleaner that maximizes the performance of your fuel system. Max-Clean restores fuel economy and deeply penetrates and cleans injectors, carburetors, intake valves and combustion chambers.

    Royal Purple's Max-Clean is EPA / CARB Compliant. Safe for use in gasoline and diesel engines and can be used with all ethanol blends or biofuel. Max-Clean can be used in both 4-cycle & 2-cycle engines and will not harm vehicle emissions equipment.

    Multiple product fleet tests were conducted on various makes and models of vehicles. Royal Purple found that after as little as one treatment Max-Clean can:

    • Improve fuel economy an average of 3.2-percent
    • Increase horsepower an average of 2.6-percent
    • Reduce hydrocarbon, NOx and CO emissions (on average 12, 13 and 18-percent respectively)
    • Prevent rough idle, hesitation and stalling
    • Prevent premature spark plug fouling
    • Reduce deposit-related engine knocking and pinging
    • Stabilizes fuel during off-season and storage
    • Superior corrosion and oxidation inhibitor

      Recommended Treat Rate: Pour entire contents of can into a nearly empty tank and refuel. One (1) can treats 15 to 20 gallons. For tank sizes outside of this range, use one (1) ounce per gallon. In two-cycle engines, use one (1) ounce per two (2) gallons.

    11722 is rated 5.0 out of 5 by 5.

    Rated 5 out of 5 by from What a Difference! I have a 2002 Ford E250 work van that receives regular oil changes and that's about how far the maintenance goes. If something breaks, it gets fixed, and that's it. Preventive maintenance is not something that I subscribe to. My van with 116K on it was running really rough, stalling, no power, and terrible gas mileage. My son told me about Royal Purple Max Clean, we ordered some and I can't begin to tell you what a difference it made. Runs smooth, no stalling, more power and better gas mileage. We ordered more and will be adding it to all our vehicles and work equipment as part of our "new" preventative maintenance program.

    Rated 5 out of 5 by from Really does restore mpg I throw some of this in with some 93 octane at the same time I do a royal purple oil change and actually notice I get an average of about 40 extra miles per tank. Definitely worth the buy.
