CRD Fuel Enhancer | Diesel Injector Cleaner
CRD Fuel Enhancer is a specialised diesel injector cleaner formulated specifically for Common Rail Diesel (CRD) engines. It cleans injectors, boosts lubricity, restores lost power and economy, improves cold starts, and eliminates the knocking and rattling that plagues worn CRD fuel systems.
THE SPECIALIST CRD INJECTOR CLEANER FOR MODERN DIESEL ENGINES
Common Rail Diesel Systems Demand Specialised Care
Modern CRD diesel engines operate at extremely high injection pressures. At high pressure, even microscopic injector deposits cause injector rattle, poor fuel atomisation, loss of power, increased emissions, and rough running. Standard fuel additives aren't designed for these conditions and often fall short.
Worn or partially clogged injectors also cause harsh cold starts, excessive smoke, and poor fuel economy — problems that get progressively worse without targeted treatment.
CRD Fuel Enhancer is specifically engineered for the demands of Common Rail Diesel fuel systems. Its high-detergency formula cleans injector tips and internal components, eliminates the harsh injector rattle common in CRD systems, and restores the precise fuel delivery your engine was designed for.
It also significantly boosts diesel fuel lubricity — critical for protecting high-pressure fuel pumps and injectors from premature wear, especially when using modern low-sulphur diesel.
Key Benefits:
- Cleans CRD fuel injectors — eliminates rattle and restores spray pattern
- Enhances fuel lubricity to protect pumps and injectors from wear
- Reduces harmful emissions — ideal before a WOF or emission test
- Restores lost power and fuel economy
- Improves cold start performance in all conditions
- Anti-corrosion protection for fuel pumps and injectors
- DPF compatible — safe for all modern diesel emission systems
CRD Fuel Enhancer is the go-to treatment for any modern diesel showing signs of injector issues: rough idle, hard starting, power loss, excessive smoke, or poor fuel economy. Regular use every 3,000–5,000 km keeps your CRD system in peak condition and prevents the costly injector failures that plague high-mileage diesel engines.

How to use it
Honestly, this is the whole job:
- 1
Measure the dose
Use the dose rate on the label — the bottle cap is your measure.
- 2
Pour it in
Add it to your fuel or oil at fill-up or service. No workshop, no tools.
- 3
Drive as normal
The clean-up happens while you work. Most people notice a difference within two to three tanks.
Precautions — the straight talk
- Keep out of reach of children. Not for drinking — it's engine treatment, not cordial.
- Avoid skin and eye contact — wash with water if it happens. Gloves are a good idea when dosing.
- Store sealed, upright and away from heat or ignition sources — treat it like fuel.
- Stick to the dose rate on the label — more isn't better, it's just wasted product.

What it's done for others
Reviews from customers of Cost Effective Maintenance Australia — our parent company. Same products, 30+ years of results, now here in NZ.
"2006 Hilux, 285,000 km on the clock. Smoked on every hill. Two tanks and it's gone — and it's using less oil between services now."
"Run it across our five Rangers for 18 months. Cold shifts are smoother, the noisy diff went quiet, and the fuel cards show it on the long hauls."
"I tell customers most additives are snake oil. Ran it through a sludged-up Territory before its service — what came out in the drain pan told the whole story."
It pays for itself
A cleaner engine burns less fuel, uses less oil and puts off expensive repairs. One bottle costs less than an hour of workshop time — and you don't have to book anything.
