ArchoilAR6900-D Max Advanced Diesel Additive Concentrate, 5L Treats 5,000L of Fuel, Diesel Fuel Injector Cleaner, DPF Filter EGR Valve Turbo Cleaner, Super Diesel Converter. (5Litre)

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

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.

Rated 4 stars as have no long term Data , I put a few treated tank fills through my mk7 ford transit , 175k on the clock , I wouldn't say it transformed the engine performance, but it is definitely smoother and seems to pull a little better .. a bit like the human equivalent to getting a good night's sleep 😅. And yes I guess I would compare I to putting premium diesel in , but then are you really saving much money in adding it yourself. I would have to do the math, but suspect there wouldn't be alot in itwith the price of fuel in the UK. But long story short , seems good 👍

Very good product. I’m using this for number of years. Keep engine running smoothly and injectors clean from soot. Highly recommended

This seems to be good quality.It's too early to give a genuine review in whether it works, but it does seem to prove the engine running, especially under speed.I'll update my review in the future if there's anything significant worth reporting back on.

Excellent productMore power better mpgCleaned the injectorsCar feels different well happy with it

Good product. Used in a high mileage VW Transporter.Seems more responsive and for the price, worth using in every fill up. I always put a little bit more than recommended (like 5ml).Lots of complaints about the bottle. Its absolutely fine and good for measuring the amount.

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.
