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: Economical and easy to use - It is difficult to assess how effective these products are in the short term. I had a problem with my Mazda 6 2.2 diesel car, inlet manifold and EGR blocked with carbon. The Mazda mechanics cleaned it out and one of them suggested using this additive ALWAYS. That's two years ago and I still am. The car is fine. Its no trouble to use and I use it as if it was a religious requirement. But who can tell what is happening down those holes without a teardown ! Time will tell ! The MPG is steady and good. The iStop works every time ( it stopped just before I had the manifold/ EGR problem ) so I'm hopeful ! Very economical in use, so, a good buy.

## 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.

### ⭐⭐⭐⭐ I think it works
*by D***V on 4 July 2025*

Got my Skoda 2.0 TDI with 12k miles about 8 years ago. I've added a (generous) dose of this virtually every time I fill the tank. With 112k miles on the clock my car is still running well. Engine sounds smooth and quiet for a diesel. I don't know how much, if any mpg it's adding, or if it's actually doing any good. All I can say is that my car starts without any problem on original glow plugs, I get around 50mpg average (70+ on a long, steady run), and no EGR/DPF problems so far. Also, it feels like I'm still getting all of the claimed 150 bhp. It appears I'm on my 5th bottle of this additive, so I've spent a bit over £100. It seems to be money well spent.
