ArchoilAR6900-D Max Advanced Diesel Additive Concentrate, 1L Treats 1,000L of Fuel, Diesel Fuel Injector Cleaner, DPF Filter EGR Valve Turbo Cleaner, Super Diesel Converter. (1Litre)

Improvement in mpg (actually got 40mpg on a motorway run from Manchester to York) and smoother running. Always use it when I buy supermarket diesel. RR SDV8. Slowed down the intervals between services as this was as low as 3k miles. Now upto 5k to 6k.

Good to use on range rover evoque diesel, few extra miles to the full tank. Slight difference in the excellration but not very noticeable. Might use again if price was a little cheaper.

PRODUCT IS VERY GOOD, ONLY BAD THING IS DESIGN. PLEASE CREATE BOTTLE SIMILAR TO MILLERS ECO MAX . BEEN USING ARCHOIL ADDITIVES FOR MORE THAN 15 YEARS AND EVERY TIME HAD PROBLEMS WITH BOTTLE. BOUGHT MILLERS ECO MAX, BUT IT IS NOT THE SAME. THIRD TIME MADE MESS AT HOME BY TRYING TO FILL ARCHOIL INTO MILLERS BOTTLE, EVERYTHING STINKS. FED UP

I have used this on both my 3.0diesels and the difference is exactly what the description tells you. I use this every fill now and you can hear the engine breathe a sigh of relief. I mix it with Shell Standard diesel nothing else. I’ve just ordered my second bottle….dont use anything else!

Mk8 transit, had surging, stuttering throttle at low speed and low revs perhaps due to dirty injectors, dropped a few mil of this in a third of a tank and within 40 miles the engine is smoother, pulls cleaner doesn't sound so much like a tractor and crucially the stuttering is all but gone. Really quite impressive value for such a small amount required.

Used this for the second fill up on my Freelander 2. What a difference, engine is much quieter. Pulls well through the gears. Very pleased.

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.

The old diesel runs smoother and cleaner. Might even be getting a few extra mpg
