Power Service Diesel Injector & DPF Flush

Power Service Diesel Injector & DPF Flush

Single-Tank Diesel Injector Cleaner and DPF Treatment for Deep Fuel-System Cleaning

Power Service Diesel Injector & DPF Flush is a fast-acting diesel fuel additive designed for periodic deep cleaning of the fuel and emissions system. One treatment targets injector deposits while helping reduce soot loading in the diesel particulate filter, turbocharger, EGR system and MAF sensor.

The formula removes stubborn injector deposits, including Internal Diesel Injector Deposits (IDIDs) and nozzle coking. Cleaner injectors can help restore balanced fuel delivery and more complete combustion, reducing the soot that contributes to frequent DPF regeneration.

Power Service recommends using Diesel Injector & DPF Flush monthly or as needed.

One-Tank Diesel Injector Cleaning

Modern diesel injectors operate with extremely small clearances and high fuel pressures. Deposits can interfere with injector movement and fuel spray patterns, leading to incomplete combustion.

Diesel Injector & DPF Flush is formulated to remove:

• Internal Diesel Injector Deposits (IDIDs)
• Injector nozzle coking
• Other deposits that interfere with fuel delivery

Cleaning these deposits helps restore more consistent injector flow and fuel atomization.

Power Service's current Technical Bulletin shows injector cleanup after a single treated tank and identifies improved combustion and restored performance as key outcomes of the treatment.

How Injector Deposits Affect the DPF

Injector and DPF problems are often connected.

When dirty injectors produce an uneven or poorly atomized fuel spray, combustion can become less efficient. That can increase soot production, placing more load on the diesel particulate filter.

Diesel Injector & DPF Flush addresses the problem from both sides by cleaning injector deposits and supporting the DPF regeneration process.

Reducing soot production at the source can help slow DPF loading and reduce the need for frequent regeneration.

REGENEXTEND Technology

Diesel Injector & DPF Flush contains Power Service's exclusive REGENEXTEND technology.

It is designed to reduce both:

• How frequently the DPF needs to regenerate
• How long each regeneration cycle lasts

Power Service reports reductions in regen frequency and duration of up to 50%.

In testing shown in the current Technical Bulletin, the distance between regeneration events increased from approximately 212 miles on untreated fuel to 423 miles following one treated tank.

Actual results depend on the vehicle, duty cycle, engine condition, existing deposits, fuel quality and operating environment.

DPF Cleaning and Soot Control

The product is formulated to help clean the diesel particulate filter and reduce premature clogging.

It also helps reduce soot and carbon accumulation affecting:

• DPF
• EGR system
• Turbocharger
• MAF sensor

This does not mean the additive can repair a physically damaged, ash-loaded or mechanically failed DPF. A filter that is beyond its service limit may still require professional cleaning, diagnosis or replacement.

Fuel Economy and Performance

Dirty injectors and frequent regeneration can consume additional fuel.

Power Service reports fuel-economy improvements of up to 10% following treatment, along with restoration of lost power, torque and acceleration.

These are cleanup and restoration claims rather than guaranteed fuel-economy gains. Results will vary depending on how much performance has been lost to deposits, excessive soot loading or inefficient regeneration.

Emissions and Black Smoke

Power Service testing reports reductions in emissions, including NOx and black smoke, of up to 50%.

Cleaner injector operation can improve combustion quality, while lower soot production reduces the load placed on the DPF and EGR system.

Actual emissions performance depends on engine condition, emissions-system operation, fuel quality and duty cycle.

Power Service Diesel Injector & DPF Flush Treatment Amounts

Add the appropriate amount directly to the diesel fuel tank according to the container directions.

Do not add Diesel Injector & DPF Flush to the DEF tank.

How Often Should Diesel Injector & DPF Flush Be Used?

Power Service recommends Diesel Injector & DPF Flush:

• Monthly for periodic deep cleaning, or
• As needed when injector deposits, excessive soot loading or frequent regeneration are a concern

It is not intended to replace Power Service Diesel Kleen +Cetane Boost as the normal every-fill-up performance treatment.

Diesel Injector & DPF Flush vs. Diesel Kleen

The two Power Service products serve different purposes.

Diesel Injector & DPF Flush:

• Monthly or as-needed deep cleaning
• Rapid single-tank injector cleanup
• Targets IDIDs and nozzle coking
• Helps reduce DPF soot loading
• Uses REGENEXTEND technology to reduce regen frequency and duration

Diesel Kleen +Cetane Boost:

• Designed for use at every fill-up
• Maintains injector cleanliness
• Boosts cetane
• Provides fuel-system lubricity
• Helps maintain performance between deep-cleaning treatments

Power Service does not recommend using Diesel Kleen and Diesel Injector & DPF Flush in the same tank. Use the Flush in place of Diesel Kleen for the tank receiving the monthly deep-cleaning treatment.

Diesel Fuel Compatibility

Diesel Injector & DPF Flush is effective in:

• Ultra Low Sulfur Diesel (ULSD)
• Conventional diesel fuel
• Biodiesel
• Biodiesel blends
• Renewable diesel

The product contains no metal or metal ions.

Power Service identifies it as suitable for diesel engines when used according to label directions.

OBD-II Codes and Diesel System Deposits

Injector imbalance, low or unstable rail pressure, excessive soot and DPF loading can contribute to certain diesel diagnostic trouble codes.

Power Service identifies fuel-system, injector, EGR and DPF-related codes as conditions that can sometimes be associated with deposits or soot accumulation.

Diesel Injector & DPF Flush may help when deposits or soot are contributing factors, but it is not an OBD-II diagnostic tool and should not be treated as a repair for every trouble code.

Persistent warning lights, failed regenerations or diagnostic codes should be properly diagnosed.
