Wynn's Extreme Diesel System Cleaner - Deep Cleaning Engine Treatment - Restores Fuel Economy & Reduces Emissions - Prevents Turbo, EGR Valve & DPF Issues - 325ml

Wynn’s Extreme Diesel System Cleaner is an excellent product that really delivers results. After adding it to the tank, the engine feels smoother, quieter, and more responsive within a short time. It’s particularly good for improving fuel economy and restoring lost performance in high-mileage diesel engines. The formula works through the entire fuel system, cleaning injectors and removing carbon build-up effectively. It’s easy to use just pour it in before filling up and there’s no smoke or harsh odour like some additives. A great maintenance product that helps keep the engine running at its best. Ideal for anyone who wants to maintain performance and prevent costly issues down the line.

Very happy with this product and have it monthly on subscription. Our T5 VW camper was dying a death on steep hills, losing power even though we have oil and filter changed regularly. Since taking this monthly, it attacks hills as it should. I recommended subscription, even though occasionally I miss a month and try a similar product if its a better offer. We have been using Wynn's extreme clean for a couple of years now, and it is a huge benefit to performance. Really easy to use, just pop it in the fuel tank when filling up once a month we use it and find the quality excellent.

Works fine

I had an old diesel vehicle and the EWL started randomly illuminating. A quick check of the codes suggested a DPF or diesel system sensor type issue. A bottle of this (and Wynn's DPF version) seemed to resolve the issue. I now add a bottle every few tanks of fuel. Resolution may be coincidental, but seems an ok product and way cheaper than a large garage bill. Probably worth a try?

This is a good product. I have definitely seen an overall improvement of the engine performance. Better starting, idle, smoothness and economy. I'm not a mechanic, but it seems to have made a definite improvement to how the engine now runs. Followed the directions on the bottle, very easy to use. Will be using again.

Noticeable improvement in car's performance after using this
