Product description

Size:20 Ounce

Max-Clean is a state-of-the-art fuel system treatment that cleans injectors, restores fuel economy and reduces both engine buildup and tailpipe emissions. Max-Clean’s proprietary technology targets both the intake system and combustion chamber and is effective on the entire spectrum of engines on the road, whether they are new or old, gasoline or diesel, naturally aspirated, turbocharged or supercharged. After multiple product fleet tests were conducted on various makes and models of vehicles, Royal Purple found that after, as little as one Max-Clean treatment can improve fuel economy an average of 3.2 percent and increase horsepower an average of 2.6 percent. Reduces Hydrocarbon, NOx and CO emissions (on average 12, 13 and 18-percent respectively). Prevents rough idle, hesitation and stalling. Prevents premature spark plug fouling. Reduces deposit-related engine knocking and pinging. Deposit build-up is a natural consequence of fuel combustion, unfortunately these deposits can have a significant effect on the performance and reliability of your engine. With Max-Clean, Royal Purple has developed a product that in most cases can bring engine surfaces back to like-new clean, restoring once-lost fuel economy and performance.
