    Rated 5 out of 5 by from If you love your car I used this product accidentally, i never used it before. After using it in my Toyota avensis 2.0 diesel my cars' performance was brilliant. It is bit expensive then the other products available but it worth. Must use. Fortunately I bought three items and use same time: Wynns Engine Flush Petrol and Diesel 425ml Slick 50 Engine Treatment 750ml Wynns Formula Gold Diesel Treatment 500ml It cost me £46.49 but it is worthy. First time I feel power in my engine. If you can afford and want to keep your car for longer, the i would recommend all three products.

    Rated 5 out of 5 by from Diesel judder on Insignia FIXED! I was having judder at low revs/speed on my 2010 Vauxhall Insignia, also not great at pulling away sometimes. Trip to dealers could find no problem, but it was getting annoying so decided to try this product. First bottle I tried seemed to improve it slightly but did not solve the issue, so after a month or two running this product and tried a second bottle. I have never had a problem since! I now use this product as recommend and the car has never been better. Tip being if one bottle doesn't work straight away, run it for a bit and then go for a second. It may have a lot of old deposits etc to clean. Worked for me!

    Rated 4 out of 5 by from Scepticl at first but it does work well My Mondeo was smoking heavily. Everything had been replaced in line with a service but it still contiued to smoke heavily under acceleration. Ive now done about 60 miles since putting this in my tank and it seems to be getting better and better. I cant comment on fuel economy yet as I'm driving around using slightly higher revs than normal but it certainly hasn't reduced any. Much better than the Redex I've used previously and I'll keep using this once a year or so.

    Rated 4 out of 5 by from Ideal for clearing out the DPF I've recently had to purchase this product a few times to clear out the DPF on my Citroen C4. It really does work well at clearing out DPF system and getting rid of the warning light. Best thing to do is make sure you take it on a nice long run and keep the revs high. I generally put the solution in my tank and then take it for a spin on the motorway. I keep the car in 4th and do about 65mph, its the only way the DPF will regenerate properly on my car. However it works well. The only reason I have given it 2 stars for value is because you can buy it a lot cheaper elsewhere.
