Diesel Pro USA is a revolutionary cleaning system built exclusively for diesel engines with modern emissions systems. Four products work together to clean the entire engine — EGR circuit, oil system and fuel system — in about two hours.
Modern emissions systems recirculate exhaust gas straight back through the engine. Carbon accumulates in the EGR circuit, coats the cooler, chokes the turbo vanes and loads the DPF. The industry answer has been replacement — valves, coolers, VGTs and filters, over and over.
Diesel Pro USA takes the other path. We temporarily adapt to the emissions system, give it a complete internal cleaning, and reset it back to OEM standards.

Adapters connect intake & exhaust simultaneously
*Times are dependent upon engine size and soot load.
Rapidly expanding high-volume foam is delivered simultaneously into the intake and exhaust side of the engine, removing buildup from every inner surface and passageway.
A synthetic oil system cleaner circulates for roughly 15 minutes before the oil change, using vapor action to reach passageways detergents alone cannot.
A one-tank cleanup dissolves internal and external injector deposits, then Ultimate 11 keeps the fuel side clean, dry and stable between services.

This unique solvent-free formula safely dissolves carbon build-up on contact. Drag the handle: same core, same lighting, one service apart. Deposits pass harmlessly through the exhaust system.
Scrubbing the DOC and DPF reduces regeneration cycles and stationary regens.
Cleaning the exhaust side of the turbo increases turbo speed and boost — and efficiency with it.
A clean EGR cooler drops intake air temperature back toward factory spec.
Powerful products engineered to work together for comprehensive cleaning results — not four bottles that happen to sit on the same shelf.
Solvent-free, dissolves carbon on contact. Restores the engine back to factory conditions.
Cuts fuel droplet size by a factor of eight and chemically bonds water for removal through combustion.
One-tank cleanup for internal and external injector deposits, including IDID in HPCR systems.
Synthetic vapor-action cleaner that decontaminates the oil system before the drain.

Technology drives innovation. When you have cutting-edge products that transform industry expectations, you design the delivery system and stand behind it. Three machine sizes, powder-coated steel, driven by shop air alone.
Engine-specific adapters connect to the intake and exhaust side of the emissions circuit. No disassembly, no removal of the EGR valve or cooler. Adapters are catalogued by make, model, year and displacement across Caterpillar, Cummins, Detroit, Ford, GMC, International, Isuzu, Mack, Mercedes, PACCAR, Perkins, Volvo and Yanmar.
The EGR & VGT Controller continuously cycles both the EGR valve and the variable geometry turbo through their full range of motion during the clean, opening hard-to-reach areas — particularly valuable on one-piece nozzle ring turbos.
The delivery system propels rapidly expanding high-volume foam through the emissions circuit on shop air alone. Both sides of the EGR circuit are cleaned simultaneously. Dissolved soot and carbon pass harmlessly through the exhaust system.
An oil change is required following the EGR and induction clean. Add Oil System Cleaner before the drain, circulate roughly 15 minutes, and drain with the used oil. Injector Cleaner runs as a one-tank cleanup, then Ultimate 11 maintains the fuel side between services.
Controller software reports commanded and actual positions for the EGR valve and turbo, plus turbo actuator load — the only indicator available for determining turbo cleanliness without disassembly. An average actuator load over 55% on nozzle ring style turbos indicates carbon loading.
PSTA has seen a dramatic reduction in engines requiring stationary regens when using the program in a regular preventative maintenance schedule.
We find that the products have freed stuck vanes in turbos regardless of mileage, with over a 75% success rate while using this product as directed.
When used at regular maintenance intervals, the replacement of EGR valves, EGR coolers, VGTs and DPFs is greatly reduced.
