Introduction

Congratulations on your selection of the CARBONCLEAN

®

 DUAL SYSTEM. By choosing this product, you 

are acquiring the most technologically advanced method available for cleaning harmful fuel system contami-
nants from gasoline & diesel engines. 

The MCS 352 is a self-contained cleaning system, designed to connect to any gasoline or diesel engine (up 
to 7.3L). Once the unit is connected, it temporarily replaces the regular fuel supply with a mixture of fuel and 
the specially formulated CarbonClean

®

 Cleaning Detergent. 

With the engine idling, the unit pumps the fuel/detergent mixture through the vehicle’s fuel system. As the 
mixture passes through the fuel system, it loosens and dissolves accumulated deposits, which then pass 
harmlessly out through the exhaust system or are removed by the unit’s fuel filter. Removing contaminants 
from the combustion chamber creates a more even burn of fuel, which improves horsepower, increases fuel 
economy, and reduces exhaust emissions.

Please refer to the chart below for the recommended service intervals:
