Royal Purple® Max-Boost is a high-performance octane booster and fuel treatment that increases gasoline octane, reduces emissions, and enhances engine performance while stabilizing fuel. Max-Boost is formulated with MMT, which delivers the best octane enhancement to help eliminate engine damaging detonation, pre-ignition, and pinging or knocking from low octane gasoline. Max-Boost is formulated for engines equipped with carburetors, port fuel injection and direct injection, as well as turbocharged, supercharged and nitrous-injected engines. Safe for use in leaded and unleaded gasolines, and alternate fuels like gasohol, reformulated gasoline, and all ethanol blends. Max-Boost is safe for oxygen sensors and catalytic converters.


  • Reduces engine knocking and pinging
  • Raises octane rating up to 30 points or 3 numbers
  • Restores power and fuel economy
  • Cleans deposits from fuel injectors
  • Restores lost power due to knock-retard in computer controlled engines
  • Replaces lead additives for protection of non-hardened valve seats
  • Stabilizes fuel

One can treats up to 25 gallons of gasoline. Do not exceed 2 ounces of Max-Boost per gallon of fuel. Pour entire can into tank before fill-up. Clean immediately if spills occur, as product can permanently stain painted surfaces. Do not expose liquid to direct or indirect sunlight. Replace cap after can has been emptied, and dispose of properly.
