Wynn'sHigh 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.

Works wonders, immediately noticed a change.

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.

I actually bought this because the petrol version worked well in my daughter`s car. One of my cars is a diesel with about 110,000 miles on it so I gave this stuff a go. I used it when I was filling up the car before my wife took it away for a few days trip. She had used about seven gallons by the time she returned. The first time I drove it afterwards I immediately noticed a great improvement in the acceleration and pulling power of the engine. I can`t say there was any further improvement after running the rest of the tank through but I was very pleased with the initial effect. Because you need less throttle for any given speed fuel consumption has improved by almost 10%. Well worth the money in my opinion.

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

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.
