Description

It can eliminate knocking, pinging, and exhaust smoke while improving start-up performance. This product is suitable for all diesel engines, whether they have turbochargers or not, and is safe for use with catalytic converters and particulate filters (DPF).

Ideally, Diesel Purge is added into the fuel filter housing. For preventive use, fill the fuel filter with Diesel Purge during replacement and add the remainder to the tank. In case of issues, the engine can be run directly with Diesel Purge through the fuel line or diesel filter.
