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.

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.

Seems to work more will be revealed later.

MY car started flashing up its engine light and i knew it was emissions . I’d had the erg replaced previously and various problems so I was loathe to spend another ton of money . Googling around brought this product up , recommended by other drivers and for the price I decided it was worth a go . It removed the engine light immediately and six months later it hasn’t come back on . I will Now periodically add this to my diesel as I understand i probably should have been doing that from the start but of course nobody tells you (!) Highly recommend this product . If I could give it ten stars I would purely for what it potentially saved me . Absolutely doddle to add to the fuel tank and anyone could do it , you don’t need to be a “petrol head “

easy to use and worked well

Ordered in the evening and delivered the next morning :). I know this is a good product and a fair price so would buy again.

I don't want to comment negatively but in my experience it didn't make a difference just yet. Have driven around 90miles a d still have the same lights on the dashboard such as dps full.... I might need a longer drive

Great stuff, keeps the turbo clean, had a problem with turbo gate sticking, this cured it
