Nov 16, 2012

Royal Purple Max-Clean is a fuel system treatment that cleans injectors, restores fuel economy and reduces both engine buildup and tailpipe emissions, targeting both the intake system and combustion chamber.

According to tests done by the company, Max-Clean can improve fuel economy an average of 3.2 percent, increase horsepower an average of 2.6 percent and reduce hydrocarbon, NOx and CO emissions in as few as one treatment. Max-Clean also can prevent rough idle, hesitation, stalling and premature spark plug fouling, and reduce deposit-related engine knocking and pinging, the company says.
