Product Description

Details

Rapid improvement in engine technology has resulted in an imbalance between engine design and fuel quality. This combined with non-optimum driving conditions can result in an accumulation of deposits in the fuel system, combustion area, turbo, diesel particulate filter (DPF) and catalytic converter (CAT). These deposits effect performance, fuel economy, exhaust emissions and engine refinement.

They can also cause engine warning lights or restrictive “limp home” conditions. To address these issues Archoil has released its latest high-strength diesel cleaner, AR6400-D MAX. AR6400-D MAX is a powerful next-generation all-in one fuel system, engine, turbo, DPF and CAT cleaner. It is the culmination of years of research and the decision to combine the original AR6400-D Engine Cleaner, AR6500 DPF Cleaner and AR6600 Turbo Cleaner technologies providing the greatest value and product performance into a single treatment.



FUEL SYSTEM CLEANER

AR6400-D MAX quickly restores engine performance and fuel economy lost through deposit buildup in key parts of the fuel system, engine and emission control systems. Molecule by molecule deposits are safely removed. AR6400-D Max helps restore variable geometry turbo operation and diesel particulate filter regeneration. AR6900-D MAX will remove all forms of deposits from fuel injectors including carbons, varnish and stubborn lacquers.

AR6400-D MAX - Engine Clean-Up

AR6400-D MAX will effectively clean older as well as modern Euro 5/6 specification fuel systems. It is suitable for all diesel engines running on pump, bunkered or bio-diesel blended fuel.

LUBRICANT

AR6400-D MAX delivers a modern lubricant helping to protect high pressure injection systems and fuel pumps during the cleaning process.

AR6400-D MAX - Friction Test Results

CETANE BOOSTER & COMBUSTION CATALYST

AR6400-D MAX contains a proven cetane booster to improve combustion efficiency and engine performance, whilst reducing engine noise. A combustion catalyst technology then facilitates a cleaner burn, improving combustion quality further.

These additional functions not only provide an instant improvement in performance but facilitate the cleaning function by keeping recirculating hydrocarbons as low as possible.

FEATURES/BENEFITS:

  • Rapidly Cleans Fuel System & Combustion Area
  • Removes Deposits from Turbo, DPF & CAT
  • Raises Cetane Index Number
  • Smoothes Rough Idling
  • Restores Lost Performance & Economy
  • Lowers Harmful Exhaust Emissions
  • Lubricates & Protects the Fuel System

USAGE INSTRUCTIONS

  • Add the correct amount of AR6400-D Max to the fuel tank first and then fill up with fuel immediately afterwards.
  • Treatment ratio is 1:100 > 1:200. A single 400ml bottle will treat between 40 and 80 litres of fuel.
  • A 5 litre container will treat up to 1000 litres of fuel.

CAUTION: Do not overdose.

  • Use every 5000 miles or use once and follow up regularly with Archoil AR6900-D Max

Worked like magic, power back, fuel consumption is getting better each longish trip... Previous owner six miles each way to work at about 45/50mph... Not good for any engine, it was choked up... And wouldn't pull the skin off a rice pudding......
Now it's pulling like a train. THANK you for a brilliant product.. Dave... (Posted on 02/02/2017)

I used this product followed by the ar6200 I noticed the engine running smother and fuel consumption went up by 3mpg. What I would like to know is does any of the archoil products clean the inlet manifold and the egr valve. (Posted on 17/05/2016)

“I ordered this last week and received some sound advice from Paul, who was genuinely helpful, giving me a lot of time and attention on the phone.

I’ve used the BG244 in the past for my diesel Lexus IS200 (2009) and it has been fine, it is not a myth and what others have been saying on the site is not just random hype. I RARELY give feedback for products as I buy anywhere online, but the truth has to be said in this case. When the Powerenhancer team said that these fuel treatments are solutions, they are not joking around!

I used the Archoil AR6400-D Diesel Cleaner and AR6300 Fuel Modification Complex for my 2009 Lexus and after a few miles of driving I felt the difference. The sluggish behaviour was gone! I had an issue where the car was pulling back and after the treatment it was gone! I prayed for a solution and this was the answer. I went to the mechanic and he quoted me £300 to clean out a part I can't even remember the name of. They said that it's a part the often goes wrong and needs to be either cleaned or replaced - this was obviously not the case. Others should try it out for themselves just like me. I'm surprised these products don't have a money-back guarantee.

Thank God and thank you Paul for all your help.”

Kind regards, Terence.

“Just a quick email to congratulate you on the Diesel Fuel Injector Cleaner. It did exactly what it says on the instructions, cured the fault code on my Saab 9-3, tried other ones but to no avail, so will order from time to time this excellent product.” (Posted on 06/01/2016)

“Thank-you for your recommendation for the fuel additive for my ‘53 plate Volvo S60 D5 with currently 186k on the clock. What a result!

With a bottle of AR6400-D applied to tank, no thump in the back and noticeable power increase, however post treatment it 100% definitely requires less throttle input to pick up revs! Also the classic diesel plume that appears when on boost has all but vanished!?! Incredible!!!

Commute mpg is up already and all of the above has been experienced just after 44 miles! I look forward to further improvements as it continues to clean lube and whatever other wizardry things AR6400-D does. Always been sceptical, but I'm a convert and after covering my next 5k as recommended, I'll be back for another batch.” (Posted on 06/01/2016)

“Hello, I drove to the south of France to visit relatives and they have a string of high mileage diesel cars and vans. I bought a bottle of AR6400-D to use on the trip. However at arriving at the host’s home, the discussion of Diesel engines came up. The conversation ended with me gifting them my bottle of AR6400-D.

Their old Renault Megane diesel with 340,000 km on the clock was completely transformed by your magic potion - they thought the car was on its last legs. Under 100 miles of driving with Archoil in the tank became quieter, faster and more responsive.

My host was so impressed with Archoil, he called his local garage owner at 11pm at night demanding to know why he hadn't stocked any Archoil.

Good luck, I think you have a new bunch of customers here in south of France. All with diesel cars and fleet vans to operate.”

Thanks.

“I’ve never written a testimonial before but your product deserves it! I have a Mondeo 1.8 TDCI which has now covered 132,000 miles and delivers 61 mpg.

On the two occasions that my engine had starting problems: once at 67,000 miles and second time at 88,000 miles I immediately used a bottle of AR6400-D.

Both times it solved it within 2 to 3 days. Since then I have run a bottle through every 10,000 miles with no problems in last 50,000 miles (5 bottles). This fuel additive makes the engine run smoothly too, however you can tell it needs it again after 8,000 miles since last bottle.”

Keep making this! (Posted on 06/01/2016)

“Dear Sirs, I have just completed a course of your AR 6400-D and the small bottle of concentrate on my Audi A6 All Road which has now completed 211,000 miles.

This product did exactly what you said it would. I had forgotten how smooth this engine could be and the Emission fault light (which had been on for 20,000 miles) went off after about 300 miles. I wish to continue with your product, so what do you recommend to maintain the continued reduction in carbon etc.” (Posted on 06/01/2016)

The following is an article I posted on the Jaguar forums, if it is of any use to you then please feel free to use it.

“Hi guys. I’m new to these forums however I’ve found them a very interesting read. I’ve had the same problem as most on here with the car showing more warning lights than a jumbo jet out of fuel! Because of the constant selection of ‘Limp’ home mode, one garage said they would have to take the gearbox apart at the cost of a couple of thousand pounds.

A couple of weeks ago the car wouldn't start at all - after 5 days of scratching my head and after reading these forums I found out about the EGR Valve and someone said tap it with a rubber mallet, which I did. Hey Presto the bloody thing started. It seemed to me that the slightest bit of dirt would make the valve stick and because the sensors really couldn't tell what was wrong all sorts of lights lit up and ‘limp’ mode engaged.

Anyway, I have solved all my problems with an amazing product called Archoil. The product was AR6400-D. It’s supposed to clean your system including the EGR. I have only had the stuff in there for about 100 miles now and the difference is amazing. I’m hoping that before long I can take the rubber mallet out of my boot! It’s embarrassing sitting in the supermarket car park belting hell out of a Jaguar engine to make it go like most cars – I’m sceptical about products like this but I was desperate and willing to try anything.”

Footnote: I am in no way connected to the makers of Archoil. Just an ordinary Joe trying to get his car to work efficiently.

Thank-you.

“Hi David, There’s a link to the AR6400-D thread I just started on thedieslgarage.com. There is no question this stuff (as well as all of Archoil’s products) sets the bar well above all others. Everyone I work with is a believer in these products - and these are master certified technicians with tons of experience, they run Archoil in all of their own personal vehicles.” (Posted on 06/01/2016)

“I've used AR6400-D on my engine to great effect - It seems to have freed up a sticky turbo too! I found it better than BG244, which I’ve used for a few years in that respect.

After using the 6400-D I then discovered the existence of AR6400-CR. Since my engine has common rail injection, please can you tell me if I should have used the CR version of AR6400 and not the D version? Does it make any difference? What is the difference between the AR6400-D and the AR6400-CR please?” (Posted on 06/01/2016)

“Hi there, firstly postage and packing - all very quick and prompt. The parcel was very well wrapped, but must have been subject to a bit of a beating as the AR6400 had seeped a little. Didn't seem to have lost much, so not the end of the world but makes you wonder what had happened to it to make the seal fail!

Anyway, onto the product itself. My car is a Saab 9-3 TiD 150 on a '07 and was averaging 38 mpg doing motorway miles at about 600 miles a week. I knew something wasn't right, but so far it's had the EGR, MAF, MAP and injectors all checked and nothing found to be wrong. The DPF has been regenerated but still the car seemed down on the economy figures and a little 'flat'. I had been using Millers Eco Diesel Power Plus with every fill-up but I thought it would be worth giving the AR6400 a go after reading about it being a 'new technology' (and not simply just a bottle of Kerosene or Two Stroke Oil).

I've now done a full tank - the exact same driving I do every week and the mpg is reading 44 mpg - I didn't modify my driving style and the car is exactly the same but the AR6400 seems to have worked wonders. In addition, it feels smoother too and generally more pleasant to drive thanks to a feeling of more torque being available.

I'd recommend AR6400 to anyone who has checked the items I have, and still feels their car is lacking. It's not a magic potion and won't fix a broken car or parts but it's really done the trick for me! Feel free to use this review - it's a good product so it's worth shouting about.”

“I recently bought your AR6400-D from your website, and only bought my Peugeot 407 HDi 2.0 in January and had just over 105,500 miles on the clock.

The car was giving me about 44.5 mpg. Since putting the AR6400-D in the car, it’s now giving me about 50.0 to 51.5 mpg. The car now runs a lot smoother and has more power WOW!! I’m impressed, once used I will use the AR6200 20ml bottle to treat 200 litres given to me as a sample.” (Posted on 06/01/2016)

My 2004 VW Golf V 2.0TDi 150,000 mls was intermittently misfiring - VCDS diagnostics identified injector fault on Cyl.No.4. Added AR6400-D and ran for 50 mls and the fault has cleared ........... hopefully for good! Re-checked with VCDS and no faults found. Great! (Posted on 28/08/2015)

I have owned a 2013 Toyota Avensis Tourer 2 litre diesel (25000 miles) for10 months and know nothing about cars! However I decided to try the Archroil AR 6400-D Pro Diesel Cleaner.
Before using it my long term average was 53mpg. Since using it I have had two full tank tests returning 58 and 59 mpg. Very pleased. I intend to use it on an annual basis as I average only 10k per annum. (Posted on 10/08/2015)
