Schaeffer's 137CTPA CarbonTreat™ Premium All Season Diesel Treatment (24-Pints) is a multi-functional, ultra-low sulfur compliant diesel fuel additive. It is formulated to prevent and control the formation of asphaltenes and other unstable compounds. These compounds are caused by the extreme pressures and temperatures encountered in high pressure common rail fuel injection systems. This can lead to the formation of deposits which plug fuel filters and foul injectors. CarbonTreat™ Premium All Season has 3X the detergency needed to provide clean-up and keep clean performance, as shown by the Peugeot DW-10 Injector Depositing Test.
