Increase Power and Reduce Emissions with Fuel System Additives from Royal Purple

Royal Purple’s proprietary technology can be found in fuel system additives that increase power, reduce emissions and help diesel engines cold-start in winter conditions like a warm sunny day.

  • Max-Clean™ fuel system cleaner and stabilizer restores your engine, helping it perform the way it did when it came off the factory floor. Due to carbon build-up, direct-injected engines suffer from a loss of horsepower and a drop in fuel economy, sometimes after as few as 10,000 miles. With our high performance fuel injector cleaner, you can reclaim peak performance while reducing emissions.
  • Beyond our gasoline fuel system stabilizer, Max-Tane™ fuel injector cleaner is perfect for diesel cars and trucks and is specifically formulated to solve problems associated with today’s new HPCR diesel injection systems. Max-Tane cleans and lubricates your fuel system, prevents gelling in cold weather and improves fuel efficiency by up to 10%.
  • For racing and high performance applications, try Max-Boost™, our unique octane booster, and gain a competitive edge for engines equipped with carburetors, port fuel injection and direct injection, as well as for turbocharged, supercharged and nitrous-injected engines.
