ARCHOIL AR6900-D MAX ADVANCED FUEL SYNTHESIS
AR6900-D MAX is an advanced fuel conditioner that is specifically designed to address inherent deficiencies in modern diesel fuels. AR6900-D MAX essentially converts regular diesel into Super Diesel but at a more affordable price point. It enhances regular BS EN 590 pump fuel but is also performant in all other diesel fuel types including bio-diesel.
AR6900-D MAX has been engineered to clean, lubricate and protect the fuel system whilst enhancing combustion performance through the use of a cetane improver and Archoil’s combustion catalyst
technology.
AR6900-D MAX is suitable for diesel car, van, bus, truck, agricultural and marine including the latest Euro 6 classification or those with the latest high pressure common-rail injection fuel systems. AR6900-D MAX can reduce fuel usage, exhaust emissions and carbonaceous deposits, which help protect the catalytic converter, turbo charger and diesel particulate filter (DPF).
FUEL SYSTEM CLEANER
AR6900-D MAX contains the latest technology in detergent performance, extensively tested to provide controlled removal of deposits and keep fuels systems, injectors and engines clean. AR6900-D MAX will remove all types of deposits from the injectors including carbons, varnish and
stubborn lacquers.
AR6900-D MAX will effectively clean older as well as modern Euro 5/6 specification fuel systems.
This results in restored engine performance, MPG and reduction in harmful exhaust emissions.
LUBRICANT
AR6900-D MAX delivers a modern ester-based lubricant helping to protect high pressure injection
systems and fuel pumps from today’s low lubricity, low Sulphur (USLD) fuels. Energy produced by the combustion process can be lost due to internal friction in the engine between the piston rings and cylinder walls.
AR6900-D MAX lubricates these areas resulting in improved engine performance and protection, making it the perfect additive for poorly-additized bio-diesel blended fuels.
STABILISER, DISPERSANT, CORROSION INHIBITOR & WATER DEMUSLIFIER
AR6900-D MAX contains antioxidants designed to stabilise and extend the life of fuel in storage. An integrated corrosion inhibitor protect fuel tanks and key fuel system components from oxidation. AR6900-D MAX prevents water emulsion and keeps water out of the fuel. Foaming is also reduced.
CETANE BOOSTER & COMBUSTION CATALYST
AR6900-D MAX contains pure 2-EHN cetane improver (up to 5 points) to improve combustion efficiency and engine performance, whilst reducing engine noise. A combustion catalyst technology then facilitates a cleaner burn, improving combustion quality further thus helping to improve performance whilst reducing fuel consumption, exhaust emissions and deposit build-up in the combustion area, turbo charger, DPF and catalytic converter.
Continuous use will reduce combustion, turbo and DPF deposits reducing the need for other dedicated cleaners or DPF regeneration cycling
SAFETY & VALUE
Only 100% active ingredients are used meaning less wastage and greater value for money.
AR6900-D Max is no-harmed tested and fully BS EN-590 compliant. It is completely soluble in fuel oils and compatible with cold flow improvers

I’ve been using AR6900D Max and AR6400 in my Jaguar XF for the past four years, and I couldn’t be more satisfied with the results. These products are incredibly easy to use and have proven to be a game changer for my car’s performance and maintenance.
Since I started using AR6900D Max with every fill-up, I’ve had no issues with the DPF, EGR, or any other common problems that can plague diesel engines. My car passes emissions effortlessly every time it’s MOT’d, which gives me great peace of mind.
I also use AR6400 once or twice a year, especially before long trips to France, and I’ve noticed that my engine runs more smoothly and even a bit quieter. It’s the perfect product for keeping everything in top shape.
I opted for the 5-litre option of AR6900D Max, and it’s been a good investment. It should last me a long time—unless my mates keep asking to try it! Overall, these products are a must-have for any diesel vehicle owner looking to keep their car running efficiently and problem-free. Highly recommended!

I had a Ford 1.6 Tdci fiesta and used AR600D I the tank and it pulled like a train. Sold the car and got a Kuga Tdci 2 litre a still using AR600D in the tank less regens more responsive and cleaner exhaust .maintenance is the key to your car upkeep and car only done 55,000 miles and regular oil changes and friction modifier will be next on my list

I’ve been using both Arcoil AR6400-DMax and AR6900-DMax for about 5 months now and I can Thoroughly recommend them.
Have owned a skoda Octavia 1.9pd auto. diesel for over 12 years and over 150,000 miles. For the last 4 years it’s been plagued with the engine going into limp mode. This was being caused by the variable vanes in the turbo seizing up with carbon and soot from the exhaust, resulting in the turbo spinning too fast for the load the engine was under. 95% of my driving consists of short trips, sitting in traffic on very congested roads. It’s an ideal recipe for clogging up the turbo, egr etc. Driving up hills and joining Motorways etc. were the most likely times for the limp mode to happen. Sometimes Limp Mode isn’t just a minor inconvenience, it can be b***** dangerous. I had a couple of hairy moments!
I tried Wynn’s turbo cleaner and also Shell V-Power for a few months. Didn’t do much. I also replaced the MAP and MAF sensors, but with little success.
Read about Arcoil products, read the reviews, and ordered the 6400-dmax. After about 200 miles I could feel a big improvement in performance. A couple of weeks later I bought a second bottle. This brought further improvements. It’s also got quieter! I now also use 6400-DMax at every fill up. The engine now revs freely. MPG has improved by around 4 MPG. The auto gearbox changes up earlier and stays in a higher gear for longer due to the improved torque. It’s been 3 months since the last Limp Mode moment! The Turbo has always been a bit vocal, [common on these engines] but now, when I put my foot down, the turbo doesn’t scream like a banshee, it’s more a low hum! I highly recommend these Arcoil products. I wish I’d discovered them sooner!

I have been using AR6900-d for 2 years on my 170 bhp Yeti. I monitor the DPF ash and it has not increased in 1 year since I increased the dosage slightly and used AR6400-D twice a year. Great product, car is very quick and returns 50 mpg round town.

I’ve been using Archoil AR6900-D Max for four years now in my Skoda Yeti 2.0 TDi 2010 vintage (VW EA189 diesel engine 110ps). After going through EGR valve, Throttle Body and Turbo soot clogging problems at around 140,000 miles (total). In the 105,000 since starting to use Archoil I have had no recurrence of such problems. Recently removed the Throttle Body for manual cleaning, 60,000 miles since last time, to find the unit was pristine! Last three MOT emission tests have read 0.00, 0.01 and 0.00 respectively on the particulates test. Last occasion the tester had to re-check the calibration on his smoke tester device, as he could not believe a car with 245,000 miles was producing a reading of zero. The car was recently back to the independent specialist who sold it to me 9 years ago, for some suspension work. The same guy wanted to know if I had the car chipped recently, as when he was testing it after the work, he reckoned it drove like a 140ps version! It has not been chipped! Have just swapped the car for a 2017 diesel Yeti and am continuing to use 6900-D Max every fill of supermarket fuel in the “new” diesel.

I have been using this since purchasing my Kia last year 15 plate. It runs smooth has plenty torque and milage is around 62 at 60mph no smell less soot and smooth running. Brilliant stuff.

I was going to scrap an old VW 1.9 tdi due to repeated emission test failures. This product gets a pass every year now and has increased fuel economy. Fully recommended.
– Dave0166
I use this product in my 2017 Evoque because they are thwart with DPF issues. Not Whilst your dropping some of this gear in ya fuel. It’s like a different motor. Idles like new and has completely enhanced the way the car drives. It feels like it’s been remapped. I will be using this product for the long term.
– Junior
Used the concentrated diesel additive after using various other makes to no effect… van woz coming up eng serv now on dash…. then going into limp mode… tried nèw air cleaner… diesel filter…. no effect…. got the concentrate added with no fuel top up on a full tank…. it took 250 miles before it stopped coming up eng serv now….. 2,500 m later still ok…. engine seems more responsive…????

Have been using another product for years which has the effect of DPF regens happening less frequently. Tried this on both our diesel cars and both are ‘regenning’ much more frequently than even with no additive. One of the cars even flashed up a dpf warning light on the dashboard – which has NEVER happened before. Have stopped using it and returned to the old product which is still working well. Regret buying 5 litres of this stuff now. Have 4.5 litres sat in the garage unused.

Have been using this on my 2001 19d for 2 or more years and it really does work. Have used redex in the past with not really any noticeable difference. For the first start on a cold winter mornings my van was very slugish untill it warmed up not with this though it run normal. I think i am getting 4 or 5% better fuel economy but i haven,t done a definitive test.Works out at about 2p a litre of diesel ( only 1ml per litre) if you buy a litre bottle which is a lot cheaper than a premium forecourt diesel

My 08 Saab 93 TTdi (180ps) had been dropping into limp mode on and off for a couple of years due to EGR, DPF, Inlet manifold clogging issues which I resolved with various treatments and additives. However the duration of the resolution was getting shorter and frequency of the dreaded limp mode light was increasing to the point where I was uneasy on longer journeys. I then came across the Powerenhancer products and started (June 2019) by dosing my fuel tank with Archoil AR6400-D MAX Professional Diesel Engine, Turbo, DPF & CAT Cleaner Concentrate and followed on with constant use of Archoil AR6900-D Max Advanced Diesel Fuel Synthesis. Well the results weren’t instant and limp mode did continue occurring but the frequency started to reduce and periods of uninterrupted motoring increased until after 2 months (approx) no more limp mode. Since then things have only been improving with less engine clatter, smoother and more responsive pick up and slowly increasing MPG, on my last long journey (Jan 2020) I achieved 46.3 MPG which I haven’t been close to for years. For me these products have been brilliant and I have just ordered my 2nd 1 litre bottle of Archoil AR6900-D Max Advanced Diesel Fuel Synthesis. Thanks Powerenhancer
– Timbo
I have been using this for over a year, after first adding the AR6400 to shock my system. My engine is very quiet both at tickover and on the road and I calculate that using supermarket diesel with AR6900 I am getting what is claimed by Shell et al for their top diesels for much less money. Very pleased with this product.
– Paul
I’ve been using this for a few years now and it’s a fantastic product. It gives you peace of mind in knowing you’re protecting vulnerable parts of your vehicle. I’m currently using it in my Transit custom and it’s running sweet as a nut.
– Chris
I’ve been using this for a number of months now and works really well. The car does not go through so many DPF regenerations and even when it does it does not take so long to complete so saves fuel and reduces the chances of engine oil degradation. Car runs smoothly and now with the recent addition of a chip it’s a flying machine (240ps Leon 184 TDI). When you work out how much money you waste paying for the performance fuel at the pump, this product is far more cost effective by a considerable margin. Go buy some!

Using AR6900Dmax after a tank full of standard diesel dosed with AR6400 & what a difference on my 13 plate Jaguar XJ 3L turbo. The cars has only 31k miles on it so I thought it was running ok, now it’s even quieter, smoother & pulls even stronger! Tail pipes have virtually no soot in them or soot on the bumper above the pipes. Never seen a DPF regent light so thought the system works as designed so didn’t expect the use of these additives to make much difference but that feeling was totally wrong.
After the last service the AR6100 friction modifier went in, now the cars even smoother & tickover sound levels are down by 3dB! So it’s doing something as well!
