    Rated 5 out of 5 by Works Well I have used this product before and I am very please with the results. Keeps the black clouds away from the emmissions. 23 October 2014
    Rated 3 out of 5 by Will try again.. Bought this product to try and clean the fuel injectors on my Megane, I read other reviews to find the best method to use it all the reviews suggest to fill the tank half full and pour the entire bottle in it but It didn't work for me as my methane still had no power and puffing out white smoke.. I am going to give it another chance and buy it again and pour in with very little diesel in the car so it is diluted stronger! Will post results again. Stay classy 01 October 2014
    Rated 5 out of 5 by Seriously good stuff Well worth the investment, I bought this because my van started to smoke quite badly, a bottle of Diesel magic straight in the tank sorted it out. Does what it says on the tin. 18 October 2013

    Rated 5 out of 5 by Good product I have used this for many years . I notice the difference after a few miles and an improvement of about 3 mpg at a 1000 miles a mouth this is money well spent 10 August 2013
    Rated 4 out of 5 by Does the job! I have used this for some time now and it does seem to make a difference. If using for the first time in a car i mix with half a tank of fuel to give the system a good clean then as product directions after that. 10 February 2013
    Rated 5 out of 5 by top class added to 4 to 5 gallons of diesel in my mates stuttering shogun and after a few days it started to behave itself 03 January 2013
    Rated 4 out of 5 by I think it worked Can't say much about the fuel economy improvement. Hasn't had an adverse effect on our engine, but our car still has a rough idle. I'll try the D-Tox at some point to see whether there's an improvement. My problem may be linked to bad injectors 01 January 2013
