Absolutely brilliant if you have a Ford with easy fill. You dont need to use the horrid wee adapter to fill it in your tank as this doesn’t need it.

Had an issue with my diesel camper van that had stood for a few months, lack of power as if fuel wasn’t getting through. Put a bottle of this stuff in drove it for a few miles and now it’s running like a dream.

The amber engine light came up on my 2020 Jaguar E-Pace indicating an emissions fault. Carried on driving for a week or so even giving it some long drives to try and get it off but it remained on. Bought a bottle of Wynn’s, put the whole bottle in with a full tank of diesel and went for a 20 mile drive. Next time I started the engine the light had gone out. A week later and it still hasn’t come back on so it certainly appears to work.

I had also put a bottle of Redex (my usual go-to potion for general engine health) in a few days previously too so between the Wynn’s and Redex it certainly worked.

Just bought a VW CC with 62,000 miles on the clock. My last car was a 140BHP with over 100,000 miles, this is a 177BHP and it felt slower. Also, the MPG was about 15% lower than expected.
Put the Wynn’s 28263 Diesel Particulate Filter Cleaner in about 30 litres of fuel just before a long drive of about 75 miles, including about 60 miles on the motorway. The traffice was a mixture of slow moving and fast motoray – I got almost 65MPG!! Very happy! That’s more than my previous lower pwoered car.

Used this product, or similar, before with decent results so no real surprises. It certainly seems to do the trick but as it’s more a case of prevention rather than cure who knows for sure ? Anyway it doesn’t seem to do any harm and maybe the car runs a tad better with rather than without the additive ! So not unhappy with the purchase.

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.

I bought this on a recommendation for a friend, he has 2 litre turbo diesel and was going in limp mode. This was recommended to them by Halfords and apparently, it restored all power back to his car. My car has been running fine but I got this anyway. I did not notice any change at-all but I guess it was preventative.

I was fully prepared for simply the ‘placebo’ effect after using this. ‘I must at be able to tell the difference…..!?!’
After 6mths of using ‘standard’ Supermarket diesel in my 2014 Grand Cherokee, (when prices went mental) I started to get issues on cold start. Engine would fire up as usual, but as soon as cold start kicked in (‘choke’ for older generation) it would suddenly run really lumpy. Only for a few seconds though, and then even out. It was winter when it began so, blamed temperature.
But it got steadily worse.
First and cheapest option was to dump a bottle of this in. (I added to 2/3 of a tank for more concentration)
I fully expected no noticeable improvement…….followed by a trip to the dealer for injector issues.

But, WOW! After 3 days the lumpy idle disappeared!
AND
I hadn’t realised the engine had also gradually got a lot louder over time (lack of fuel probably) and suddenly it was lovely and quiet again! (for a V6 diesel anyway)
PLUS
Performance has notably changed too! Feels a lot stronger, doesn’t need to rev as much to produce the power. Delivery is so much smother and effortless now.

BRILLIANT.

I’m going to run one more bottle through, just as a final flush.

But to say I am impressed, for 6.99, is an understatement!

The product ‘should’ be the same wherever you buy it. Had a fuel problem on my Land-rover a few years ago and the garage/mechanic advised this (he did not specify the brand) type of product. The issue was that the Land Rover was struggling to start, and struggled to get up to 50; then started spluttering over 50 (this went on for several weeks). I put this fuel system cleaner in with 20 litres of diesel and went for a long drive. The vehicles response initially hadn’t altered! Then I switched the engine off and the vehicles computer reset and the problem was solved. Now I put a bottle through the fuel system every year before the MOT (that date is just a reminder for me) and have been driving trouble free since. If it’s the first time you have used this, I might suggest checking with your mechanic first, and then put it in with your fuel, drive normally for a few miles (20-30 miles) to get the vehicle up to normal operating temperature, then, as you accelerate (e.g. when joining a motorway) you might notice a bit of smoke coming from the exhaust as the system cleaner does it’s job. I’m no mechanic, but I wouldn’t advice leaving this in your vehicle for too long (I put it in and take one or two long drives over a couple of days until the 20-30 litres of fuel has gone, then refill the diesel tank). The chemicals in this product dissolve the rubbish/gunk that has built-up in your fuel system, so it might not be good to keep fuel cleaner of this strength in the vehicle too long!
