It works
I have purchased Redex for my vehicle for many years and find it reduces omissions but you also get extra mileage from your fuel. I did a test years ago and found I got 15 more miles from a full tank of fuel. I can recommend this product.

Excellent product and great value for money. The quality exceeded my expectations and it arrived quickly and well packaged. Very easy to use and exactly as described. I’ve been really impressed with the performance so far and would definitely recommend to others. Will happily purchase again in the future

This is a good alternative to the other Redex DPF cleaner on the market.

A great product that restores power and looks after your engine.
I have another brand of diesel on repeat order every month with Amazon but it went up in price and this was on offer so we had this instead. Did the job perfectly! Our VW T5 camper was losing substantial power on hills, dispite regular oil and filter changes. Using a diesel system cleaner it flys up the hills. Will definitely buy again. No negatives. Just returned from the Brecon Beacon Mountains and the camper went like a dream.

Great product for preventative use
A must have for any diesel car driver, especially if you tend to use standard low octane diesel in your vehicle for cost reasons. Top up your car, add half a bottle of Redex and it will help keep your engine clean and assist in your emissions. Great price on Amazon too. No impact on vehicle or driving, just an excellent preventative measure!

A must have for diesel vehicles
I recently tried the Redex Diesel Fuel System Cleaner, and I have to say, I’m pretty impressed. With a 250ml bottle, it's easy to use, and I appreciated the clear instructions on how to add it to my tank. After using it, I noticed my engine seemed to run more smoothly. It felt like it was breathing better, if that makes sense. My fuel economy has slightly improved, too, which is always a plus! I didn’t experience any rough starts or stalling, and my engine noise was a bit quieter. One thing I really liked was that it didn’t leave any mess or residue; everything seems to work as it should. I’ve tried other fuel cleaners before, but this one feels like it really did the job. Plus, knowing that it helps keep the fuel system clean just gives me peace of mind. Overall, I’d definitely recommend giving the Redex Diesel Fuel System Cleaner a shot, especially if you're looking to enhance your vehicle's performance without any hassle. It’s a solid product that lives up to its claims!

Not really sure yet of it's merits - time will tell..
I bought these two bottles after reading the reviews here. So far, its early days - literally - or weeks now I should say, as I poured a bottle in as per the instructions in the fuel tank. I must admit so far, the car has not burned up the road like the legendary ‘bat out of a warm place’ or have I noticed any fuel savings but the good news is the car has not so far conked out (technical term, popularly used in the last century) or getting 'an extra fifty miles more per gallon' but if it cleans the fuel system up, then all well and good. I will use it over the coming weeks and months/whatever and hopefully may see some wonderous signs that it’s doing some good. However, how one can judge all the merits I have read about, without resorting to scientific apparatus or equipment, is slightly beyond me as no two people drive the same - or is this the motoring equivalent of the medical world's placebo? - or the updated version of the 'Emperors New Clothes'? Therefore I have awarded three stars in my rating as I am not completely sure so far.
