Product Overview
Millers EPP Diesel Injector Cleaner 400ml β Restore Diesel Fuel System Performance
Millers EPP Diesel Injector Cleaner 400ml is a concentrated diesel fuel treatment developed to remove deposits from fuel injection systems, helping restore engine efficiency, acceleration and reliable diesel performance.
Manufactured by Millers Oils as part of its Emission Performance Programme (EPP), this specialist fuel additive targets contamination and deposits that can affect diesel injector operation and combustion efficiency.
As diesel vehicles accumulate mileage, injector deposits may affect fuel spray characteristics and contribute to reduced power, poor throttle response, increased fuel consumption and higher exhaust emissions.
Millers EPP Diesel Injector Cleaner is formulated to tackle these deposits as part of appropriate vehicle servicing and maintenance.
Why Choose Millers EPP Diesel Injector Cleaner?
1. Removes Diesel Injector Deposits
Fuel injectors must deliver fuel in a controlled manner for efficient combustion.
Deposits within the diesel injection system may interfere with this process. Millers EPP Diesel Injector Cleaner contains concentrated cleaning agents designed to remove contamination and help restore cleaner fuel delivery.
2. Helps Restore Power and Acceleration
When injector deposits reduce fuel injection efficiency, the engine may struggle to deliver its expected performance.
Cleaning the injection system can help recover power and acceleration lost due to deposits. This is particularly useful for diesel vehicles experiencing gradual performance deterioration.
3. Supports Better Fuel Economy
A cleaner fuel injection system can support more efficient diesel combustion.
By reducing deposits that interfere with fuel delivery, Millers EPP Diesel Injector Cleaner may help improve fuel efficiency where injector contamination is contributing to poor MPG.
Actual fuel economy improvements vary according to engine condition, driving style and the underlying cause of the problem.
4. Helps Reduce Exhaust Emissions
Poor injector performance can contribute to incomplete combustion and elevated exhaust emissions.
Millers EPP Diesel Injector Cleaner is formulated to help reduce emissions associated with contaminated diesel fuel injection systems.
This makes it a useful maintenance consideration before an MOT emissions inspection, although no additive can guarantee an MOT pass.
5. Concentrated 400ml Treatment
The convenient 400ml bottle is intended for diesel fuel-system cleaning as part of vehicle maintenance and servicing.
Always use the correct quantity in accordance with the product’s label instructions.
How Diesel Injector Deposits Affect Engine Performance
Modern diesel engines depend on accurate fuel injection to maintain combustion efficiency.
Over time, injector deposits can develop and affect the quality and consistency of fuel delivery.
Potential symptoms of injector contamination include:
- Reduced engine power
- Sluggish acceleration
- Poor fuel economy
- Increased exhaust smoke
- Rough or uneven engine operation
These symptoms can have multiple causes. A diesel injector cleaning additive is not a substitute for diagnosing mechanical, electrical, fuel-pressure or emissions-system faults.
Millers EPP Diesel Injector Cleaner for Diesel Vehicle Maintenance
The Millers Oils EPP range is developed around specialist cleaning and emissions-related maintenance treatments.
The Diesel Injector Cleaner specifically targets the diesel fuel injection system rather than acting as a dedicated DPF cleaner, turbocharger cleaner or replacement for regular servicing.
It may be considered when injector deposits are suspected or as part of an appropriate preventative maintenance programme.
