Excellent stuff especially for the catalytic converter and long lasting.
Quick delivery and excellent condition and really good stuff especially for the ford focus ecoboost cars. Value for money as it lasts for 3 months. I'd highly recommend this product to family and friends and other people but their is an even better one now which has dual action.

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.

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.

Worked well at first but engine light is back on
Bought this again as worked well first time but engine light has come back on again, trying again as dirty cat may be more serious!
