Description
When a diesel starts knocking, pinging or smoking under load, deposits inside the fuel system and injectors are usually to blame more often than a mechanical fault. LIQUI MOLY Diesel Purge is built to clean that fuel system and the injectors within minutes rather than over several tanks, recovering lost power that deposits have been quietly stealing.
This 500mL treatment is meant to be added directly into the fuel filter housing rather than the main tank, letting it act on the injectors and fuel path fast and directly instead of diluting through a full tank of fuel.
- Cleans fuel systems and injectors within minutes of application
- Restores power lost to deposit buildup in the fuel system
- Added directly into the fuel filter housing for concentrated, fast-acting cleaning
- Eliminates knocking, pinging and visible exhaust smoke tied to dirty injectors
- Improves cold and warm start-up performance
- Increases overall operational reliability of the fuel system
Add it into the fuel filter housing on any diesel engine showing rough running symptoms and let it clean the system before your next start. IPD Racing carries Diesel Purge for owners and shops who want a quick, direct fix for deposit-related diesel running problems.
