Ideal for anyone who wants to maintain performance and prevent costly issues down the line. Review: Genuinely, Pleasantly Surprised! - I was quite sceptical of just how effective a small bottle of Diesel cleaner could be with used with my 11 year old vehicle. My diesel car has been used mainly for very short journeys over a period of several years, so has suffered the usual DPF and EGR issues that are expected when you don't properly take a diesel vehicle for longer/hi-revving journeys. My situation has now changed with a new job and I have to travel about 30 miles each way to work and back - I immediately noticed that the car had become extremely sluggish and really did not want to rev easily when trying to match the speed of an adjoining main road. The DPF and EGR had previously been cleaned by a local garage but given I live in quite a remote location I had not has need to drive on an 'open road - motorway etc' to be able to maintain a decent speed in order to maintain the cleaned components. (Also, the current cost of Diesel really encourages super-efficient driving). Now that I need to travel further to work, the car was not happy to rev beyond 2000RPM which made progress and acceleration very slow. Hills were a nightmare and the car really felt like something was severely holding it back (I thought something mechanical was wrong with it, even though no lights were showing on the dash). I read that Wynn's products were supposed to be good at cleaning out fuel and exhaust systems - so decided to give the Extreme Diesel System Cleaner Treatment a go before booking the car back into the garage. I added the whole bottle of treatment to about 40ltr of diesel, having ran the tank low and pouring the treatment first before fuelling up - to help with mixing in the tank. I was very sceptical, but I thought that for a few quid over a possible several hundred for garage diagnosis/repair that I'd give it a go. For the first 50 miles, not a lot changed - but during driving the car along a long stretch of the A1(M) the engine really seemed to clear its throat and suddenly seemed to be able to rev up a lot more easily. I didn't really notice until nearing my destination where I had to filter onto a roundabout and accelerate up to speed. The engine revved much quicker and could probably have reached the red-line. Acceleration was much improved and over the next 50 to 100 miles the vehicle has become far more responsive. I have noticed a genuine economy increase of 6 to 8 MPG with much better engine performance. I'm not making this up or sponsored or anything like that! Just trying to be helpful in my review. I appreciate that my circumstances may be unique in that my car was probably fairly coked up and not able to complete a powerful combustion process, but adding Wynn's Extreme Diesel System Cleaner really does seem to have had a positive impact on my engine performance and fuel economy. For reference, my vehicle is a Mitsubishi Outlander with a 2.2D Diesel engine which now produces 56MPG on a 30 mile commute each way (driven at 60mph with moderate acceleration as required). I hope this review is useful. If your diesel engine is lacking in performance and mechanically sound - maybe give Wynn's Treatment a go, it certainly does seem to have had a positive effect on my vehicle and I feel that it has saved me potentially spending a lot of money on professional garage services to bring the performance back in to check. ## Features - Causes serious eye irritation. - Causes skin irritation. - Harmful to aquatic life with long lasting effects. - May be fatal if swallowed and enters airways. - car parts ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00FZLCHT6 | | Best Sellers Rank | 114 in Automotive ( See Top 100 in Automotive ) 5 in Fuel Systems | | Brand | Wynn's | | Customer Reviews | 4.6 4.6 out of 5 stars (3,674) | | Date First Available | 18 Oct. 2013 | | Item Weight | 300 g | | Item model number | W12264 | | Manufacturer | Wynn's | | Manufacturer part number | 12264 | | Model | Wynn's 12264, Xtreme Diesel System Clean, 325 ml | | Package Dimensions | 21.6 x 8.5 x 4.5 cm; 300 g | ## Images ![Wynn's Extreme Diesel System Cleaner - Deep Cleaning Engine Treatment - Restores Fuel Economy & Reduces Emissions - Prevents Turbo, EGR Valve & DPF Issues - 325ml - Image 1](https://m.media-amazon.com/images/I/71DXOOOWZpL.jpg) ## Questions & Answers **Q: once in the half full tank, do you then fill the tank up or just use the half tank of fuel** A: Put this in then fill up so it mixes better or so you think it mixes better lol **Q: I have a 2.2 dti Vectra b that misfires, would it help** A: It wouldn't do any harm to try. It cleans out all the carbon deposits built up in the diesel injectors, that carbon build up could be causing the misfire. It worked for me. Give it a go and follow the instructions on the bottle :-) **Q: How many treatments does this contain** A: The bottle contains enough for one treatment. The label states to add to half a tank of fuel (20-30 litres) **Q: Is this a detergent, a lubrificant or both?** A: Detergent I suppose, it helps clean the injection system and the EGR valve and helps the pdf stay clean. I have used 1 bottle in half a tank so far and the motor is definitely quieter and smoother to drive with a much even tick over. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Powerful Cleaner That Makes a Noticeable Difference *by B***A on 8 October 2025* Wynn’s Extreme Diesel System Cleaner is an excellent product that really delivers results.
