CRD Fuel Enhancer Mini FAQ

How much do I use?

CRD Fuel Enhancer is a super-concentrated formula. Standard dosage is 1ml treats up to 8L of diesel, so use 10ml per 80L of diesel. Simply divide your tank size by 8 to calculate the standard dose.

Do not overdose. A double dose should only be used where injectors are severely worn, as recommended by CEM. Not suitable for petrol engines. Minor measuring variations with the squeeze bottle are generally not an issue, however routinely overdosing is not recommended.

How much diesel does 250ml treat?
Up to 2,000L of diesel.

Can I use it in petrol engines?
No, diesel only.

Is it DPF compatible?
Yes.

Will it void warranty?
The page states it is safe to run through diesel engines and will not void a new car warranty.

Why Replacing Injectors May Only Be a “Band aid” Fix     

Knight’s Toyota dealership had a 2007 Hilux arrive with a bad and unmistakable rattle, and all the injectors scored off scale readings. The engine was shaking, rattling and knocking a lot, indicating a costly replacement of at least $4000 for new injectors.

The owners were offered CRD diesel fuel additive instead of paying for costly replacements. Using this effective product saw the Hilux injectors testing “as new ” and performing soundly. In this case, the injectors were actually fine, and the root cause was restored by using a diesel fuel additive returning full cleanliness to the injectors. It also worked by providing necessary lubricity to better cope with the high temperature, high pressure, and fine tolerances of the common rail system.

Like all automotive systems there’s no lack of horror stories about problems with common rail diesel engines. Our fuel system cleaner is the real- life FIX for most common rail issues and adds life to your system. Benefits include:

• Cleans the entire CRD fuel system
• Concentrated injector cleaner
• Boosts diesel lubricity
• Anti-corrosion protection
• Restores power & economy
• Complete treatment
• 250ml treats 2000L of diesel

Using this product will help you save between $ 1500 to $20 000 in replacement parts to ensure everything is running smoothly long-term.

 

Try Our System Cleaner Additive Before You Rebuild

By using our system cleaner additive, you can:

• Prevent, eliminate, or minimize noisy injector rattle from your CRD engine caused by noisy valve tappets. 
• The injector could be fouled by contaminant or is seizing due to inadequate lubrication. Excessive fueling would likely be causing detonation inside the combustion chamber, instead of smooth combustion.
• Clean the pump & injector deposits and disperses contaminants as they form.
• Boost lubricity.
• Provide exceptional anti-rust protection to pumps and injectors

Is your fuel consumption going through the roof, or is your vehicle performance suffering? Save anywhere between $2000 to $20,000 on replacement parts and motor repairs by using our additive.

CRD Injectors and pumps are expensive, run incredibly fine tolerances, and are highly stressed due to enormous pressures and high temperatures. Compared to older technology diesel fuel systems, they are totally unforgiving of any contamination. Small amounts of water or contamination will wreck pumps and injectors and are generally non-repairable, meaning replacement components are required.

The damage doesn’t always stop with injectors and pumps, another common problem includes sticking injectors resulting in melted pistons. Costing around $10,000 to $20,000 for replacement. Compared to the cost of our treatment were saving you a considerable amount of money with less interruptions in using your vehicle. 

CRD engines have been developed to meet the latest emission standards, and diesel fuel sulphur is now very low for the same reason. However low sulphur fuel happens to compound another problem, lubricity! Pumps and injectors rely on diesel fuel for lubrication and with its reduction, they must get the proper treatment. 

 

About Common Rail Diesel (CRD) 

The Common Rail Diesel (CRD) injection system is the most recent development to achieve ever more stringent diesel exhaust emission standards, but it is currently associated with widespread problems, including engine rattles, expensive injector and fuel pump failures, injector sticking, stalling problems and rapid piston and liner wear. Problems have been documented across a wide range of engine suppliers, including Toyota, BMW, Volkswagen, Nissan and many more.

Cost Effective Maintenance have specifically developed our fuel additive ‘CRD Fuel Enhancer’, to address rattles, and provide smooth operation of fuel pumps and injectors. Used routinely, it will increase the service life of fuel systems and minimize the potential for the above problems.

The CRD system requires a significant increase in operating pressure compared to earlier systems. Fuel system pressures of up to (and above) 30,000 psi are required, and combined with ultrafine tolerances of diesel pumps and injectors, achieve superior fuel atomization for cleaner combustion. There are several factors that place significant additional stress on this system, compared to earlier diesel injection systems…

1. The increased operating pressure causes higher loadings on equipment, and this places a bigger demand on the fuel’s lubricating ability.
2. The higher pressure causes much higher fuel temperatures, which can actually degrade the fuel, forming fouling deposits within pumps and injectors.  Such deposits interfere with the fine tolerances, to cause sticking, malfunction and injector wear. This risk increases if using biodiesel blends, since biodiesel by nature, degrades faster.
3. Diesel sulphur levels have been reduced, to reduce smoke emissions. However, sulphur provides lubrication, so lowering sulphur levels can result in greater wear to very expensive fuel pumps and injectors.
4. CRD engines are designed with much finer tolerances within pumps and injectors, as well as piston to liner clearances, making them much more susceptible to deposits, and also the presence of any water contamination in the fuel.

CRD Fuel Enhancer provides strongly enhanced fuel lubricity, superior deposit control for fuel pumps and injectors, and exceptional anti-rust/anti-corrosion protection. While it’s recommended as a routine preventative step for CRD engines, it has been shown to eliminate severe injector rattle, restore operating performance and economy. It is designed specifically for Common Rail Diesels, but is suitable for all diesel engines. It is not recommended for petrol engines.

Many Common Rail Diesels are also prone to building high levels of soot in the oil. For this reason, we also recommend using the Flushing Oil Concentrate. 

 

 CRD Fuel Enhancer – Independently Tested & Verified Under ASTM Diesel Standards

CRD Fuel Enhancer has been independently verified under ASTM D975 and related standards, confirming treated diesel meets fuel specifications with excellent lubricity, low sulfur, and no contamination. Field use reports include improved combustion stability, reduced engine deposits, lower maintenance requirements, and extended engine life, supported by laboratory verification of ASTM and CRD test results.

What does ASTM verification mean?

ASTM verification confirms that diesel fuel treated with CRD Fuel Enhancer meets strict international standards for lubricity, cleanliness, carbon stability, and overall fuel performance. These certifications scientifically validate the effectiveness of CRD Fuel Enhancer, demonstrating that it reliably improves fuel efficiency, protects engines, and enhances operational performance according to recognized testing protocols.

Not just for high Km vehicles! 

Case Study:

Hey gents, just wanted to say thanks for a great product. I’ve just done 10,000 clicks on my Hilux and used your product from the start. No rattles at all unlike my mates that doesn’t use anything. Currently at Moreton Island from Melbourne amazing place so much fun. Good to know I can rely on my motor staying clean and working at its best.

Thanks Gasso

 

CRD saves Prado TD with petrol in diesel!

Case Study:

Report from Knight’s Toyota (Tristan) Their customer had purchased a new Prado TD and were travelling. After a 240km drive the Prado stopped and wouldn’t restart.

It was subsequently delivered by tilt tray to Knight’s Toyota (Leongatha VIC), where they were told that the owner had accidentally refuelled the Prado with 130L of petrol prior to driving the 240km. Service manager, Tristan Wilson advised the owner to expect a very costly rebuild as it was almost inevitable that a new fuel pump and injectors would be required.

While Knight’s had a lot of success rectifying injector problems with Cost Effective Maintenance’s CRD Fuel Enhancer, they didn’t expect it could save this engine. However, they decided to give it a go.

After draining the contaminated fuel, a strong dose of CRD Fuel Enhancer was added to 20L of diesel, and the fuel system bled. To their surprise, the engine started and within 5 minutes of rough running it cleared. A diagnostic check indicated that everything was OK, and the vehicle was test driven and then returned to a rather happy owner. Follow up communication with the owner confirmed that the engine was performing perfectly.

This kind of personal service from the Team at Knights Toyota is outstanding!

 

2012 Colorado 4×4 dual cab gets petrol in the diesel

Case Study:

This customer was using CRD Fuel Enhancer in the diesel of his Colorado. He was running low on fuel so put $20 in till he got to his usual servo to fill up. It ran a bit rough after a while & he thought he might have got some water in the fuel, so checked the filter drain & all clean. He put in some more CRD Fuel Enhancer as extra lubrication & protection against rust.

It seemed “OK”sh  at highway speed so drove the 80km home. But into local traffic it struggled to get any revs above idle!

So next morning it was tray topped to the Holden dealer, who soon reported that there was petrol in the diesel, and that Colorado fuel pumps don’t handle petrol or water and it will need to be replaced. But when the job was complete, there was some good news…they couldn’t fault the pump or injectors. The system had all been cleaned out and was ready to pick up!

 

Knight’s Toyota, Leongatha (VIC)

Case Study:

Hi Brid, I have attached the dyno sheet of the Hilux you have mentioned in the add. This dyno run was done after the vehicle had done a run to Cape York with your CRD additive. Before it had left for Cape York all injector feedback values were off the scale, all reading –5 to +5 (these should be around –1 to +1 to be in spec). It was rattling, shaking and knocking alot. We sent the customer on his way with your product and trust of it to take the vehicle to Cape York without causing any damage.

Once the vehicle returned, these feedbacks on all injectors were around –0.5 to +0.8. Customer couldn’t believe the results. Whilst here for the service, we put the vehicle on the dyno before and after, after using your FOC and AW10 you can see the broad increase in torque and power right through the rev range. This vehicle was still using your CRD at the time it was on the dyno. From experience, with brand new Hilux’s we have put on the dyno for comparison, these vehicles are only making 70 to 85 RWKW. So the results of your product on a car that has done 160,000km is absolutely outstanding (105.4RWKW, we have never seen a stock Hilux make this much power!). I look forward to using your product on more vehicles in the future and keeping you updated with dyno results to prove your products.

Thankyou

Tristan Wilson, KNIGHTS TOYOTA (Leongatha VIC)

 

Komatsu PC15-2 excavator…Toughest test yet for CRD Fuel Enhancer!

Case Study:

I have a worn out, old excavator that I bought for at-home landscaping. It might get used 1 or 2 times a year. Recently I did a small job, and just before I parked it up the revs were fading. I thought I ran it out of fuel. So 3 weeks later I thought I should refuel it and bleed the system. But then I noticed the fuel filter was full of water. It was through the fuel pump and injectors…it didn’t run out of fuel at all.

It hadn’t been refuelled for about 4 years, which had FTC Decarbonizer and Cleanpower in it, but it had built condensation. The pump pistons seemed to be seizing. I could only get a bit of water and rusty stain out in dribbles. My only change of recovering it to running state was to free up the pump, so I put CRD in the fuel tank and a strong hit in the fuel filter. I could only bleed a small amount through the pump, so I did a bit each day, by cranking it over a few times, then leaving it to soak over night. After a week of this, I reconnected the fuel lines and she fired up and sounds just as good as before.

 

D4D Hilux Ute fuel savings

Case Study:

Paul Burgess purchased CRD Fuel Enhancer for his Hilux (70,000km) for preventative reasons, as he did not have any issues with it. He tows a camper trailer, and will normally sit on 100kph where possible. He recorded these fuel consumption figures while towing.

Tank before using CRD…15.3L/100k

1^St Tank with CRD…14.2L/100k

Paul consider both to be similar driving conditions, and didn’t expect to see such an improvement of this size.

 

2005 R51 Nissan Pathfinder 2.5 litre Turbo Diesel

Case Study:

Hi Guys, I have been using your products since discovering them in 4WD Action Magazine a couple of months ago. I drive loaded with a steel roof rack, bull bar, winch, drawers, fridge, etc, etc. It has 235,000 km on the clock, and sees its fair share of bush work.

I’ve always had a rattle in the morning, and I know it’s a sticky injector. I’ve poured all sorts of crap into that fuel tank, from “injector cleaner”, to 2 stroke oil, with no change. I tried your CRD Fuel Enhancer, thinking, “here goes, more money down the drain.” Well, wasn’t I amazed when the Pathy started running quieter, smoother and more economically, from about 150 km from the first dose. I even gave some to my mate across the road to try in his very rattly 2.8 ltr GU Patrol. We both agree, both engines are quieter and smoother.

Next, I tried the Decarboniser. I’m still within the first 20 hours, but already I have noticed a difference in smoke output and general performance.

Yesterday is where I became disappointed. I got some of your Flushing OIl Concentrate, and following the instructions to the letter, changed my oil. Today, I drove the usual 115 km to work, from Melton to Beaufort. Usually within this time, my oil would be the usual thick black. When I got to work, I thought I’d check the oil, feeling sure it would be black as usual. I pulled out the dipstick, and sure enough, I nearly had a heart attack. The dipstick had no oil on it!! I then had another look. I realised the dipstick had the correct amount of Penrite’s finest on it, but it was so clean I couldn’t see it.

Why am I disappointed? For years, I’ve tried different brands of fuel and oil treatments that claim to do magical things, but never live up to the promise. I could probably buy a new car with the money I’ve wasted. Finally, a product that does exactly what it claims to do. Each and every one of your products that I have tried so far has done exactly what it says it will do. Thank you for bringing these products to us. I will certainly do my best to spread the word.

Thanks Guys
Sean Murphy.
