Archoil AR6900-D Max Advanced Diesel Additive Concentrate, 2 x 250ml Treats 500L of Fuel, Diesel Fuel Injector Cleaner, DPF Filter EGR Valve Turbo Cleaner, Super Diesel Converter. (2 x 250ml)

The media could not be loaded. I’ve been running Archoil AR6900-D Max in my 2007 VW Transporter with fairly high mileage, and the difference has been noticeable. The engine feels smoother, starts easier, and seems to pull better under load. Fuel economy has also shown an improvement, which I wasn’t really expecting but was a welcome bonus. For an older van that’s done a lot of miles, this additive has really freshened things up and given me more confidence in its performance. Definitely worth the low price tag compared to others and I’ll continue using it!

good quality fuel additive, the engine actually smokes a little less and runs more quietly

Fuel whiles it works. However, to clean the dpf and all the rest I'm still waiting to find out unfortunately. But it is a good product to buy. Noise level still applying to work on. Yes, it value gor money.

I read many reviews on different additives. Went with this and I can actually notice the difference. Excellent stuff

Excellent additive. Solved my slight misfire on my diesel injectors and boosted my acceleration and fuel economy by about 10%, getting around 560 out of a full tank instead of around 500 miles.

I own a 2012 Skoda Yeti 2.0 Diesel FWD & for the past couple of weeks its been blowing dark smoke out of the exhaust quite badly until the DPF warning symbol finally appeared on the Dash. I got the manual out & it seems this is not unusual for a Skoda if you dont drive it like a racing car, apparently the DPF clogs with soot as a result of driving locally at the now famous 20 MPH Welsh Assembly's speed limit everywhere, as this is nothing more than a Golden Retriever taxi for walks & the beach I drive with obvious due consideration for my 4 legged passenger in the back, consequently, I have invested in this treatment purely to keep the DPF cleaner. I cannot comment on the long term results yet but I promise I will in a few weeks time. Complaints about the container from other purchasers are correct, Ive never seen such a bloody silly set up.I sourced an empty Colegate Mouth wash bottle washed it out & dried it then put 60ml markers up the clear outside using my wifes kitchen measuring jug (clever eh) & decanted 300 ml into the bottle & put it in the back of the passenger seat & I will simply use it each time I fill up. The rest I shall leave in the shed. As for complaints about the smell, It smells identical to Wynns Injector cleaner to me, hardly that objectionable. I have given it 5 stars as it would be ridiculous at this stage to do otherwise. Watch this space, as they say, I will update. NOW BEEN USING THIS DPF CLEANER SINCE SINCE THE BEGINNING OF FEBRUARY EVERY TIME I FILL UP & CAN CONFIRM THAT MY DPF LIGHT HAS NOT COME ON SINCE PLUS I HAVE CEASED DISCHARGING CLOUDS OF SMOKE FROM MY EXHAUST. NOT CONVINCED MY FUEL CONSUMPTION HAS IMPROVED AS PER OTHER REVIEWS BUT THAT WAS NEVER THE REASON FOR USING THIS PRODUCT. INCIDENTALLY HAVE NOW PURCHASED MY SECOND CONTAINER. BE AWARE THOUGH THAT IT REALLY DOES COME IN THE CRAPPIEST CONTAINER IMAGINABLE FOR POURING.

Well it works. Improves performance and less black smoke when using cheap supermarket fuel. A bit expensive for what it is. I would purchase regularly if the pocket allows

So, I tried AR6900-D Max in a BMW 535d GT used on a regular 1353mile (2177km) trip through UK, France and Spain over 3days. Three tanks of diesel, 70ml added at first fill (70litre tank), and 50ml at next fill ups (50litres).TLDR: Didn't notice or measure any difference in fuel consumption or performance.This car usually returns between 37mpg to 39mpg doing motorway speed limits (70mph, 130km/h and 120km/h in each respective country). I was hoping to crack 40mpg which my old 530d GT could do (same size engine but with one turbo rather than two).Well, after 1353miles I was disappointed to see the trip computer (after reset at start of journey) showing 38mpg.This trip is with the same tyres and pressures, same filling stations, but at different time of year. It seems air temperature and headwinds make a bigger difference to mpg than this additive.To note, the engine is well serviced (oil changed every year) with BMW LL04 spec oil, now at 110000miles. Manifold/AGR (AGR = EGR in German) replaced several years ago due to soot build up jamming the swirl flaps, so intake should be relatively clean. DPF is intact with zero soot on exhaust tips (just light grey ash deposits). And the only running issue ever noticed was related to faulty glow plugs/controller making initial cold/winter starting a little lumpy/rough for a few seconds before settling at idle (now rectified).So it could be that as this engine is running perfectly fine, that the additive makes no difference compared to a car that may have underlying faults or running issues.I'll use it again on the return leg to finish off the bottles, just to confirm and edit if I notice changes.As a footnote this additive improves cetane value, which should help combustion. However if fuel quality is already optimal and engine condition is good then obviously it's not to going to make so much difference.It also smells exactly like the Eolys (176/ PATs/ powerflex) fluid that automatically adds fluid to the fuel on some 1.5/1.6 peugeot/citroen engines (and older Ford and volvo's with the same DV6/DV5 engine). So it's possible it contains similar ingredients and probably no use to you if you have a car with a functioning Eoyls system.Dosing is simple enough, but store it upright in an air tight ziplock bag, as if you know what Eoyls is like to smell/handle, this stuff is just as bad... nasty!3 stars based on the fact it does contain ingredients that should help with combustion efficiency, but I couldn't validate any claims in real world use.Even at its discounted price of £11.96 for 500ml it equates to nearly 0.24p per litre of diesel or £1.67 per 70litre tank. And with no difference in fuel consumption, it actually increases the vehicle running costs.Edit: (16Dec2024) After a return leg of the same 1135mile journey, fuel consumption was actually slightly worse. But I've tried a few doses in a Seat Altea with the 130ps 2.0TDi PD (BKD) engine, which is used for local 20-30min commutes on mixed 30mph and 60mph roads and that appeared to be about 1mpg better. So again not really worth using.
