Excellent 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

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.

Good for Maintenance, But Don’t Expect Big noticeable Changes
I’ve used Redex Diesel System Cleaner a few times in my BMW 1 Series and, to be honest, I haven’t noticed any massive or immediate difference in performance. That said, it’s easy to use, quite cheap, and I still use it occasionally as a preventative maintenance product rather than a performance booster. A few friends have mentioned they’ve noticed improvements in the overall smoothness and running of their cars with regular use, so results may vary depending on the vehicle. For the price, it feels worth using once in a while to help keep the fuel system clean, but don’t expect dramatic changes overnight..

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!

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!

It’s good, but will it solve all your problems?
So I do have an old 2008 C class, and this does definitely provide a slight boost in performance - making the car feel 10 years newer. I’m not entirely sold on the long term benefits as I feel the performance drops after 1-2 tanks when I stop using it, (I attempted 4 full tanks using redex) and I’ve never noticed a huge difference in noise. I would say in my experience it’s easy to use, and worth the boost in performance when the price is on offer, in most cases I would weigh up how much a premium diesel is vs adding this into a tank of cheap diesel. I am trialing Archoil brand of fuel additive to compare the difference, so I’m curious to see if there are any!
