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!

Good Value Fuel System Cleaner for Routine Use
I’ve been using this product on my Land Rover Discovery 3 and have seen modest but noticeable benefits. The vehicle feels smoother when pulling away, and there appears to be a slight improvement in fuel economy. Results aren’t dramatic, but given the low cost and ease of use, it offers good value as part of routine maintenance. Only downside is the smell / pour, I haven't managed yet to not drop a bit on my hand when pouring.

Cleared Diesel Smell
Used this on my Renault Clio just before the MOT and it made a noticeable difference. The engine ran smoother, and the strong diesel smell that had been lingering was gone after treatment. Easy to use — just pour it in with a full tank. It’s not a fix-all, but for a quick clean-up and emission boost, it did the job nicely. Definitely worth keeping a bottle handy.

Works on old diesels, better mpg.
I put one of these into my tank every second fill and doing the same commute every day I managed an extra 50miles out of the tank. (VW T4 1.9tdi, usually get 600miles, averaged closer to 650 using this)

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!
