    Rated 5 out of 5 by Bang on I have a2012 Audi Q7 with 115000 miles And in just half a tank what a difference the power is unbelievable mpg 3 mpg better Response is better and runs smoother Definitely buy this again and it was my 6 year old lad that said try this dad when we in the car shop Good lad 24 April 2016
    Rated 2 out of 5 by Millers Diesel asditive Did not do much difference to my Honda 2.2 diesel engine. No change in economy. Only noticed that the fuel burnt better and a slight increase in throttle response. To be honest-we can get similar or better improvements if we use V Nitro Super Diesel fuel which has a higher cetane value 28 October 2015
    Rated 5 out of 5 by Millers Diesel Power Ecomax Having purchased a second-hand, low mileage diesel saloon car recently, I noticed a somewhat lumpy idle although the engine ran very well in all other respects. I added one dose of Millers Diesel Power Ecomax at the next fill-up and I believe there was an immediate, significant improvement which has been sustained. It is early days and I look forward to adding another dose at the next fill-up but I am very satisfied with this product so far. 24 July 2015
    Rated 5 out of 5 by Keeps injectors clean and smooth I have been using the product for nearly two years and on diagnostic testing the injectors are within their original tolerances not bad for a 12 year old engine. Using cruise control on Mways and keeping to 65mph my 2litre engine returns between 48 to 52 mpg. So all in all an excellent product just wish there more two for one deals :) 23 July 2015
    Rated 5 out of 5 by I'm a convert I first used this in my 2010 2.4D5 Volvo XC60 a few months ago. I never believed in fuel additives until now, After only one dose I noticed a difference in the well known lumpy D4 engine. Recently I ran out of additive and went a few tanks without any, it was then I realised the difference it was making. Not only to MPG, 3-4 MPG improvement through town, but also the running and the DPF regeneration frequency. I have no science to prove it but I can tell you from my experience I'm converted to it. 29 June 2015
    Rated 3 out of 5 by Slightly worse fuel economy Used this in my Renault Scenic 1.5dci and noticed no difference at all other than my car became a couple of miles per gallon worse . The smell from it was unbearable no matter how I tried , I couldn't get rid of it .,that is until the post office totalled my car and I got a new one :) 26 June 2015
    Rated 3 out of 5 by Ignore insructions... For first use - slip in at least three measures of the detergent. It will take a few hundred miles to feel the difference! I put in a Mondeo 2.0 TDci - no problems with a twelve year olde engine. 24 January 2015
    Rated 5 out of 5 by Millers Diesel Power Ecomax I add this product every time I fill up with diesel(max capacity).It keeps the injectors clean, gives my Sportage 4x4 smoother acceleration and slightly more M.P.G. excellent product 10 January 2015
