Archoil AR6400-D MAX Pro DPF Cleaner 400ml & AR6900-D MAX 250ml

Hiya well what can I say but amazed. I have a peugeot boxer and if you have had one you know how sensitive all the sensor are. If one is out your black smoking. Well I brought this archoil cause of the reviews and glad I did. I am only have a tank used but I can honestly say I can feel more responsive. No smoke at all . Runs smooth and nice tic over. Will defo use again in 5001 miles

I don’t usually leave reviews, but I felt this deserved one based on real world results. Over the years I’ve tried plenty of diesel treatments and fuel cleaners, and to be honest most have made little to no difference. This one, however, has been genuinely impressive. I own a 2016 VW Passat Estate 2.0 TDI (150bhp) with around 110,000 miles. Before using this, I was averaging roughly 50 mpg. About halfway through the first treated tank of cleaner, I noticed the average had already increased to around 54 mpg – with no change at all to my driving style or routes. After finishing the tank and continuing with the treatment, the improvement carried on. Now, after using a few treatments, I’m consistently seeing 62–64 mpg. I wasn’t expecting results like this, especially given past experience with similar products, but it’s been a very noticeable improvement for me and with the current cost of fuel being high it’s a welcome improvement. Would definitely recommend.

Amazing product, I have a 16 year old X5 that started to clog up the EGR and get sticky EGR errors. When you get any errors on how the car breaths it will block DPF regenerations, so I also had a blocked DPF; so after clearing codes and dosing my tank of fuel with this - I set off for a drive and saw the DPF successfully regenerate 20 minutes into the drive. The key point here is that if the product also lowers the combustion temperature for the soot to break up and leave - so it can passively recover the DPF whilst also unstick the EGR. Car drove much better afterwards and could feel the power and responsiveness come back. Still running on the AR6900 so that the EGR and inlet restores gradually over time.

A good and useful supplement for fuel and engine and excellent effect.

Always comes immaculately packaged and spot on time! The product is of average price however the results are very much above average. I've used alternatives in the past and always returned to Archoil for assured quality results. I've unstuck sticky turto vanes and restored Egr's . If you care about your diesel engine then buy the best -- Archoil 🚌

Great product made a difference straight away

Excellent product and very easy to use, you can definitely feel the difference after use. Yoy can hear the car getting louder as it cleans the dpf. 100% recommended

Needed to clean a RGV valve, very simple to dose the tank , works well,have bought the additive as part of a package, I haven't used that yet , so will right a review once I've used it !
