    Rated 5 out of 5 by from MIRACLE CURE My car was running horrendously, jumping, chuggy and juddering going up any hill or when car was put under pressure. Always using car in low gear other wise it would stumble as if it was going to stall. One morning it was horrendous, so jumpy and noisy then the management light came on. Garage said it was the injectors, to put 2 bottles of this in with low petrol and run around for 30mins. Then fill up with petrol and it will run lovely. I thought no way as car was driving like a pig! But within an hour of putting 2 bottles of this in it was running smooth, no juddering and back to normal. Total miracle cure. I will be using this now every 4000 miles, like my mechanic told me to do or any long journey to give it a good clean through. A+ product.

    Rated 4 out of 5 by from V6 odd judder/jump Seemed to be missing a spark now and then so thought chuck a bottle of this in, (i like the idea of whole bottle not messing about over several tank fills) and its fixed whatever the problem was.

    Rated 5 out of 5 by from Well worth the money, saved from MOT failure Last time I nearly failed MOt exhaust emission test, this time round I was prepared. On full tank, add this in, give it a good 90mil run on motorway and it should do its magic.

    Rated 4 out of 5 by from So far so good.... I brought this product as my car kept on breaking down when it was low on petrol and it was also consuming petrol fast. My mechanic had advised that this problem could be caused by grit in the fuel tank. I have been driving my car for over two weeks since using it, so far so good. Only thing is that my car is still consuming quite a lot of petrol but not as bad as before. If any one is having problems with their car like I have described i suggest giving this a try.

    Rated 5 out of 5 by from Amazing this product stopped me taking my car in to a garage and getting my car pulled apart. my car kept cutting out just after starting and ran rough, after using this just once (with a full tank of petrol) it was fixed. This was my last hope after 3 mechanics had told me my car was in need of repair, it has been 4500ish miles and not a problem now. THANKYOU STP!!!!
