Wynn's Diesel System Cleaner DIRECT APPLICATION Flush - Code W25241
The professional-grade Wynn's Diesel System Cleaner – DIRECT APPLICATION (Product Code: W25241) is an ultra-concentrated, high-strength chemical purging treatment engineered for the immediate decontamination of diesel injection loops. Unlike standard additives, this fluid is poured directly into the primary fuel filter housing to secure an un-diluted flushing action before combustion. Developed to dissolve stubborn carbon restrictions, it restores mechanical compression parameters while significantly reducing black smoke and structural tailpipe emissions.
Design Details and Functionality
This heavy-duty flushing cleaner features a high-density active formula that enters the fuel pump and injector lines directly, completely bypassing main fuel tank dilution. The chemical compound dissolves varnish deposits on internal pump surfaces, provides active high-boundary lubrication to fuel system components, and restores the original spray pattern geometry of the injector nozzles. Upon entering the combustion chamber, it targets and breaks down stubborn carbon scaling layered on valve seats and piston crowns, optimizing thermal efficiency and restoring proper cylinder compression metrics. The benefits of this direct, closed-loop treatment carry over downstream to minimize soot accumulation, protecting the mechanical efficiency of the turbocharger housing, oxidation catalyst, and Diesel Particulate Filter (DPF/FAP).

Application Directions and Workshop Procedure
WARNING: DO NOT ADD THIS PRODUCT TO THE MAIN VEHICLE FUEL TANK!
- Step 1 (Warm-Up): Run the vehicle engine until it reaches normal operating temperature, then switch it off.
- Step 2 (Disassembly): Remove and completely drain the existing fuel filter or the integrated primary filter housing box.
- Step 3 (Filling): Pour the full contents of the 325 ml bottle directly into the empty fuel filter or housing box. Do not pour into the tank. Top up with clean diesel fuel if additional volume is required to clear air gaps.
- Step 4 (Reassembly): Reinstall the fuel filter into position, verify correct sealing alignment, and start the engine.
- Step 5 (Cleansing Drive): Immediately drive the vehicle for a distance of at least 3 km (2 miles) at a moderate speed to enable steady fluid cycle circulation through high-stress zones.
- Maintenance Schedule: For maximum system protection and to avoid power drops, execute this procedure every 6 months.
