Wynn's High Performance Diesel Fuel System Treatment - Enhances Combustion, Improves Acceleration, Reduces Fuel Consumption & Black Smoke - 500ml

I recently tried the Wynn's Formula Gold High Performance Diesel System Treatment (500ml) on my diesel vehicle, and I'm incredibly pleased with the results. From the get-go, the application process was straightforward and mess-free, thanks to the well-designed bottle. After using it, I noticed a significant improvement in engine performance. The engine runs smoother, and there's a noticeable decrease in exhaust emissions, which is a big plus for me as I'm conscious about my carbon footprint. Additionally, fuel efficiency seems to have improved, saving me a bit at the pump over time.What really sets this product apart is how it effectively cleans and lubricates the fuel system, reducing maintenance needs and prolonging the life of engine components. It's evident that Wynn's Formula Gold is engineered to boost diesel engine performance while also focusing on environmental benefits.Given the positive changes I've observed, I believe this treatment offers great value for money. It’s a small investment for significant benefits, from enhancing engine performance to contributing to a cleaner environment. I highly recommend it to anyone looking to maintain or improve their diesel engine's health and efficiency

Used it on our 2 diesel cars (VW and Skoda). After 15-20 miles driving you could already feel and see (mpg) the positive changes, which I've observed. Therefore I honestly believe this treatment offers great value for money. It seems a £12.94 investment for significant benefits, from enhancing engine performance to contributing to a cleaner injector/engine. I can now (from my own experience) recommend it to anyone looking to maintain or improve their diesel engine's health and efficiency. Now time will tell how long it will last. Thank you and good luck with your ‘Diesel’ engine. 🏎️

I purchased this product for about £12 during the black Friday sale.I followed the instructions and added the 500ml bottle to a tank of fuel.Driving an older landrover my car is a heavy and sluggy old diesel so wanted to see if I could give it some fuel treatment.Within a 20 or so miles, I noticed that the car was more responsive and less hesitant in all gears. Nothing revolutionary spectacular but certainly a noticeable difference.I've yet to see any improvement in my mpg but driving an older diesel, I don't drive with a view of saving fuel..Overall I am happy with the output of the product for the modest price point and I will likely repurchase in a few months time and use again.

I recently purchased a high mileage diesel Vauxhall Grandland X and I’ve been putting one of these in every full tank of fuel and the improvement in the engine performance has been great. You can really tell this is working and the MPG is increasing. It has quietened the engine and helped reduced smoke from the exhaust. Worth the money and I’ll continue to use it for a few more months.

This is by far the best fuel additive I have used and I've tried quite a few. Added this and Wynn's turbo cleaner to half a tank of fuel to try and sort an overboost error, less than 1/4 of a tank used and no more error, car also runs more smoothly in general. Bonus that it has the long neck that is compatible with the capless filling system on my car

Good for the job not as good as Forte stuff but worth buying

This VAG PD Diesel engine (2001 vintage) has had an easy life, being low mileage and apparently well maintained. It is always run on Shell V-Power or BP Ultimate fuel, or equivalent premium fuel. Therefore I wasn't expecting much of a difference, but the result was quite a shock! The engine runs noticeably smoother and quieter, with more power and fuel economy has improved by around 8%. I shall now be using this at least every change, or maybe more frequently.

Before using this the long term fuel economy was roughly 55mpg. With this product in a tank of fuel the fuel economy went down to 50mpg, subsequent tanks are back up to 55mpg, so it doesn’t look like it’s had any effect on fuel economy sadly. I hope that it’s done something for the innards of the thing but alas no way for me tell.
