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

I recently tried the Extreme Diesel System Fuel Injector Cleaner in my car after noticing it was feeling a bit rough during acceleration. I must say, I'm impressed with the results.After using this cleaner, the roughness disappeared, and my car's performance noticeably improved. It felt smoother and more responsive, especially during acceleration. Additionally, I noticed a slight increase in fuel efficiency, which is always a plus.What I appreciate most about this product is its effectiveness. It did exactly what it promised, clearing up any issues related to fuel injectors and restoring optimal engine performance.Overall, if you're experiencing similar issues with your diesel vehicle, I highly recommend giving Extreme Diesel System Fuel Injector Cleaner a try. It's a simple and cost-effective solution that delivers tangible results.

Bought in the hope of solving a minor over-revving issue on a Kia Carens, when going from 2nd to 3rd gear. It worked first time after just a few hours! Superb product and a world away from Redex. Highly recommended.

Will put it in our 2010 Fiesta 1.6TDCi tank on next fill-up of around 40 litres of diesel.It is not easy to know if it does any good, but will probably stop injectors from sticking open with varnish on the needles due to age and high mileage.

I purchased this product for my 2011 Freelander 2 which had become a bit sluggish and hesitate on the accelerator.I applied the full container to approximately half of a tank. I was mindful that I didn't want it to diluted in a full tank.Within about 100 miles after use, that is when I began to notice an improvement in the engine response and quality of the drive.Previously it would take a couple of seconds for the car to respond to a request for more speed but now it's instant. I've also noticed a reduction in the loudness of my turbo.I can't say that I've noticed my MPG increase but I dare say that is largely due to my driving style.I will begin to use more often and apply every 3-6 month or so given how my car is an older diesel.Happy to recommend.

Right ok I don't write many reviews but I thought this deserved a review to help people who may need to get this. So I noticed my car was running very sluggish and then I had a check engine light come on, anyway the code was P0401 which points to the EGR valve having an issue, the car felt awful and was running constantly in limp mode and reducing the power, i thought oh no a massive expensive job coming here so I had a look around to see if I could fix it myself and came across a review to buy this and try it first, why not at this price it was well worth the gamble and did it deliver!! I added the full bottle to a half tank of fuel by the time I got down to around a quarter of fuel left I could feel the car performing a lot better and wasn't feeling sluggish anymore, I didn't clear the check engine light but it just went off on its own and the car feels great, so yes I highly recommend this stuff if your having the same problem or you just want to get your car feeling and performing better.

Put this in my 3.2 Ranger just as a little bit of preventative maintenance. I was actually surprised that there was quite quickly a noticeable difference in performance. Made acceleration smoother and got rid of a flat spot that I’d learned to live with. Will definitely use again

I honestly can’t tell you if it made any difference on my car. I’ve used it and it’s no quieter than it was before… that said my car is a high miller and regular use of this product may be of benefit.Good value for money if you what to used on a reoccurring basis.

A great product. I have a 18 year old Chrysler 300C. I was advised to use this about five years ago. I have never looked back. My car loves and I love it. It seems to have a made a real difference. I don’t do a lot of mileage but I add a full bottle to a full tank of fuel. I make sure I never run out and I always carry a bottle in the car just in case I need to fill up.
