Works well. Very happy with the result
My engine management light had been off and on (mainly on) for many months with a cat efficiency error. I'd sceptically tried three bottles of Cataclean spread over this time with no effect. On the verge of having a mechanic friend get involved I thought I'd have one last go with Wynn's. Within minutes of adding the light had gone off and after around 100 miles the engine certainly feels smoother and more responsive, reporting better mileage on the computer. Still early days but it seems to have done the trick and saved me a bunch of cash. Wish I'd tried this one first!

Cleared fault quickly
Engine light came on and diagnostics showed o2 sensor fault. Thought I would just give this a try on a nothing to lose basis.One week later, no engine light and no fault showing. Very pleased.

Instructions in GERMAN!!
Just received this product. Much to my amazement the instructions are in GERMAN! Yes, I did peel the label.Surprisingly enough, I do not speak German.Come on Amazon please advise me of the logic behind that stroke of brilliance, this is the UK!!Yes I can and did look up the instruction online but there may be people who cannot and anyway why should I?Not a good start.

This sorted my fuel trims / rich fuel problem
I was sceptical at first as I've used other fuel injector cleaners like Redex and Carlube before without really noticing any improvement. I recently had my car fail it's emissions test, as there was a rich fuel condition with the fuel trims which was messing with the catalyst. I used Wynns (added a more concentrated mix in the fuel tank) and within 20mins of driving I noticed an immediate difference. I checked the fuel trims and they had balanced out back to normal. Petrol economy has been brilliant since using this as the usual amount of petrol lasts almost another half a week longer. Will use this again every 3 months. Brilliant item.

It got rid of the troublesome engine management light.
After having my engine management light come on and a visit to the garage I was informed the the o2 sensor wasn't working properly and the fitter suggested I try a cleaner, so I purchased 2 of this product and used one and on topping up the tank used the other one and the engine light has been reset and hasn't come back.
