Excellent!
This was excellent. Saved me a fortune by not having to take my car to dealers to clear fuel injectors. Going to use every 7500 kms as recommended. Car driving smoothly and fault light has turned off. Happy days!

Does the job!
Vauxhall Vectra C 1.8i SRI 140bhp engine..Before:Noisy injection and Jerking when idle, slight mis fire with eml coming on on cold starts or after driving for considerably amount of time, sluggish, Lambda bank 1 fault code would come up along with fuel trim bank 1 lean. Pinking issues when going through the rev range.After:From reserve fuel, 40 litres of She'll V power mixed with the full contents of this bottle. Went on M11 drove 50 miles there an back 70mph to 90mph. Day & night difference withing the hour!Car now idles and purs great! So far, no eml came back on, once engine is at optimum temperature or on cold starts. Pulls great and most of all, overall the engine & injection system sounds as it should. Only time will tell if its permanent or not I suppose. No more hesitation or pinking issues through the rev range and gears.Will be using again on the next full tank to have peace of mind it's done what it's intended for!For me, it's worked great.Car has had a recent air mass cleaned out using wynns throttle body cleaner, oil, oil filter, air filter, fuel filter & plugs changed around 60miles prior to using this product so this could be a major factor also.My advice would be to fill up fresh fuel from when the reserve fuel light comes on with quality fuel not E10 rubbish, around 30 to 40 litres for it to be more concentrated within the tank. Will give it another go soon!

Worth the money.
Tried this in my daughter`s car as the MOT was approaching and the previous year`s HC reading had been 180 so I thought too close for comfort to the 200 limit. Ran a tankful through and refilled for the test. HC reading this year was a hard to believe 5!! Oil and oil/air filters changed same as the previous year so presume it was this stuff certainly doing a very good job. Very pleased and will use it again.

Notice the difference
Just wanted to share that my car is driving like a dream lately! It feels so much more responsive, and I don't feel like I'm lagging at all. And the best part? I'm filling up my tank way less often. Whatever's going on, I'm into it! Hope it lasts!
