Redex Diesel Fuel System Cleaner 250ml, Diesel Additives To Remove Harmful Emissions, Maximise Performance & Increase Fuel Economy With Redex Fuel Additives For Diesel Engines, Suitable For Hybrids

Although it doesn't say so in the description you only need half the bottle so it's cost effective and appears to be doing the job well.

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!

Happy with this product - first time purchased on Amazon, previously purchased when on offer at Tesco to see if works - works well and has improved performance on my diesel car / use 125ml before topping up my cars diesel dot his twice a month and my old 16yr car runs like new - would recommendOnly issue buying on Amazon delivery before 10pm ? Would prefer 2hr window - it’s a product every diesel owner should use

Obviously I dont have the professional tools to test this but my engine works fine and I'm convinced there is an improvement

I’ve been using Redex Diesel Fuel System Cleaner in every tank for a while now. To be honest, there’s no obvious evidence that it works — but at this price, it definitely doesn’t hurt. It gives me peace of mind knowing I’m doing a little extra to look after my engine.Since I started using it regularly, I haven’t had any issues with performance or fuel system problems. Whether that’s down to the Redex or just good maintenance, I can’t say for sure — but I’m happy to keep using it.For the cost, it’s an easy habit to stick with. Cheap, simple, and no downside — I’ll keep adding it to every tank!

Best fuel additive by far. I've tried several on my ageing diesel (wynn's; stp) but this is the best. Added it to a nearly full tank then immediately did a 200 mile motorway run. Within minutes I could hear the engine running smoother and the mpg improved noticeably too. All at a great price. Winner.

Not sure if it works as it didn't fit the fuel cap of my Ford S-Max, the neck couldn't get past the inner caps that block anything unwanted from getting into the tank, so the bottles contents proceeded to pour itself down the side of the car.This is more my fault than the products fault but something to be aware of! I have since discovered you can get nozzles for avoiding the exact situation I ran into on here e.g. https://www.amazon.co.uk/dp/B09KNNPPD4

This was bought for my Ford Fiesta diesel car 2009 version. She has been smoking and emitting a strong vapour on starting especially in cold weather. The MOT three weeks ago stated 'injectors' as an advisory. Within two weeks of adding redex to the full tank the effectiveness is noticeable. There is no longer an awful smell and smoke on starting the ignition. I prevented leakage this time around by purchasing a suitable funnel for diesel additives (also from Amazon). It is a good size for two shots (one per tank of fuel.I suspect that redex has done a good job of cleaning especially the fuel injectors. I am pleased with the quality of this product and will purchase again, looking out for half price deals when they come around occasionally.
