Review: It actually does a fantastic job - 7 month use! - I've yet to see the cleaning power as i'm not testing it and comparing before and after in my diesel car but the improved starting capacity has been noticed as I used about 30ml whilst on about 35 ltrs of diesel in a 50ltr tank. I will check my egr in a week or two to see how much it's helped keep that clean as I disconnected my egr to partially clean it whilst in place just before using this product. For the price you get more than one use worth, you get quite a few so this is a product to last over a year depending so for maintaining the fuel and helping the system it's well worth the money. I'm already seeing an improvement to my average MPG which while pottering about town doing short trips is very beneficial. EDIT: After 7 months of use doing a lot of short journeys I can say without a doubt this is a perfect product for keeping a diesel in optimal health as my system runs better, it's cleaner and i'm never having issues with starting, my average mpg has risen to 31mpg which is a huge improvement over the 22mpg I was seeing before I started using it, and if i go on a longer journey it continues to rise until im back to my working day routine doing short trips, and if i take my car out on the NSL roads i'm seeing upwards of 36mpg - did i mention that cold starts aren't an issue anymore? The engine runs so much better with this product in it with the correct amount ie 1:1000 ratio so 1 ltr=1ml, for my 53 ltr tank i need two squirts of this bad boy as they are about 25ml each. I swear by this product as i've had concerns about my dpf and egr getting clogged and being at risk due to my driving habits and after having my egr out twice over the last 7 months to inspect it i can confirm this product is actively cleaning the system, it's not making the egr spotless but the buildup of carbon has been drastically reduced and the EGR is less like a carbon-geode cracked open, even my egr valve solenoid is relatively clean. I'll be forever buying this and adding 70ml to every tank before i top up with new fuel, it's a incredibly affordable product that works like a charm! Please do wear gloves when handling the bottle as while it's not the worst smell in the world you don't want it getting on your hands and then on the interior of your car where you will smell it for weeks.
Review: Improved DPF Regeneration and Good Value for Money - The short version: Archoil AR6900 has noticeably improved the DPF regeneration process on our high-mileage Nissan Qashqai 1.5 dCi. The longer version: After more than 40 years as a car enthusiast, I’ve tried plenty of so-called miracle additives — many of which turned out to be little more than snake oil for tired diesels. So I approached this one with a fair degree of scepticism. We bought a used Nissan Qashqai 1.5 dCi with over 155,000 miles on it. It had been meticulously maintained, but we knew that using it mainly for short journeys (under 10 miles) would likely lead to soot build-up in the DPF. I monitor the regeneration process using an app, and the miles between regens were quite low. Although the car was completing regenerations (no failed attempts), temperatures rarely exceeded 600°C and soot levels would only drop to around 3–4g — never fully clearing. We started adding AR6900 at roughly 50–60ml per 50 litres of good-quality diesel. I’d also take it for a proper drive once a fortnight to ensure the regeneration process was triggered whilst monitoring it. After the fifth treatment, I noticed a clear change: significantly more miles between regens, regen temperatures increasing to around 650–670°C, and — for the first time — soot levels dropping to 0g. That had simply never happened before. I don’t monitor MPG closely, so I can’t comment on fuel economy, but in terms of DPF performance there has been a definite improvement. From a cost perspective, it also makes sense. Even allowing for the additive, it still works out cheaper than regularly filling up with premium diesel that claims to contain similar detergents and cleaning agents. For me, it’s a more cost-effective way of achieving comparable — if not better — results. I’ve since started using it in a 23-year-old diesel as well and have already noticed smoother running after just a couple of partial fill-ups.

## Questions & Answers

**Q: Can these be refilled using the 5 litre version?**
A: Hi, these are not refillable.

**Q: How much is used per tank of diesel fuel ?**
A: 10ml for every 10 litres of fuel.  For example, a 60L tank would require 60ml.

**Q: can anyone tell me the mpg increase they got using this if any  ?**
A: I have been using this now for 8 years. My MPG has increased from 23 to 28 with a 1996 Fiat 2.5 in a 3,400 kg motorhome. That is equivalent to about 20% improvement one free gallon for every five. The first couple of doses saves the price of the complete bottle. You are effectively paid to use it. Performance is also enhanced with down gearchanges nearer the top of hills or not at all.
Fuel consumption is calculated on full-tank to empty-tank miles. I can achieve 50MPH by the time I reach the end of a motorway downhill slip-way where before it would be about 40.
If you're sceptical, try it - I was but I'm glad I overcame that. 
I've just ordered another bottle.
I've just bought a Fiat Doblo 1.9 diesel - I'll try it in that next.

### ⭐⭐⭐⭐ Worth a try
*by S***Y on 29 November 2024*

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 it with the price of fuel in the UK. But long story short , seems good 👍
