Powerful Cleaner That Makes a Noticeable Difference
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.

Engine TLC
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.

Appeared to solve a diesel engine warning light issue.
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?
