Proper Usage of LIQUI MOLY Diesel Purge

Using LIQUI MOLY Diesel Purge is a simple and straightforward process. Start by ensuring that your engine is turned off and cool. Locate the fuel filter and remove it. Connect the LIQUI MOLY Diesel Purge canister to the fuel filter’s outlet using the provided adapter or attachment. Next, connect the fuel line to the canister’s inlet.

Once the canister and fuel line is properly connected, open the valve on the canister to allow the LIQUI MOLY Diesel Purge to flow into the fuel system. Keep the valve open for the recommended duration specified in the product instructions, usually a few minutes. After the allotted time, close the valve on the canister and disconnect the fuel line and canister from the fuel filter.

Finally, reinstall the fuel filter and start the engine. Let it run for a few minutes to allow it to circulate through the fuel system. It is normal to experience some smoke during this process as the product works to clean the injectors and remove carbon deposits. Once the smoke dissipates, you can resume normal engine operation.
