XPCL Combustion Area Cleaner

The CLEANER phase of the XPCL treatment involves adding this non metallic petroleum based solution to the fuel at 1:100 ratio. When added to the fuel the cleaner dissolves the resins and gums holding the combustion debris in place. The CLEANER therefore  prepares the engine for the continuous application of XPCL lubricant.

Note that new or recently rebuilt engines do not require this one-off treatment.
