Dipetane 1L Fuel Additive | Improve Fuel Economy | Reduce Emmisions | DPF Cleaner Diesel and Petrol | Flush and clean Engine, Injector and EGR valve

I initially bought this item to unstick my Honda EGR valve the car had drivability issues being a diesel with two EGR valves High and low the low side actuator was sticking .The DPF was Clear. I added this Cleaner and immediately the drivability changed .I carried out EGR Actuation test to both EGR valves wk 1 low side failed. Adding more of this product engine ran smother . Test 2 added more even better test stilled failed low side but the drivability got better Added 500mil at each half a tank drivability improved no end. Autel scanner test 3 .Car drivability is now spot on the tests cleared and both EGR actuator are clean and passed with the product. I will now add this when I add fuel its a game changer cleaned my clearly previous chocked up DPF system up can now runs well. Saved me £587 because that's how much the low sided EGR valve costs it's working with the help of this product cannot praise it enough

I have this on subscription and use it exclusively in my vehicles. It’s a natural product with solid science behind it, unlike some of the so-called fuel additives that do nothing. I’ve noticed improvements in fuel economy and emissions, and it gives me peace of mind knowing I’m using something that actually works. Far better than the usual snake oil on the market!

Bought this product to use as to help maintain fuel systems and emissions on car.Arrived with no cap on bottle and slight leak on bottle, contacted supplier, they apologised and are sending out replacement no quibble

Good product

This is my second bottle of this stuff. It really does work it has quite my diesel engine also runs alot smoother I also get more miles to a tank using this then without it. I will continue to use this stuff long term more cost effective in the long run. I was using redex for years until I was recommended by a friend I wouldn't go back after using this. Highly recommend it

First off I've used several different products on my 2 cars and this one is brilliant.I've waited until I've done a good amount of miles before doing this review and here's my results.Firstly I had a dpf sensor issue causing a long persistent engine light and this product cleared the dash light.The increased mpg it states has actually been verified by both my cars, especially my diesel German estate car. It's increase is 10mpg!.My petrol car a 3.0 ltr supercharged v6 has gained 6 mpg.It's functionality is brilliant and the bottle is marked out in dosages of per 20ltrs fill up.Your under no pressure to afford a full tank of fuel like some products do.It's cleaned alot of carbon from my petrol car too.I have already purchased another and find the price reflects value for money in my opinion.I have only positive things about this product and nothing negative comes to mind at all.

Bottle neck is very narrow.Jammed in fuel filler cap.2thirds of contents went in before I was able to remove bottle.

This actually works, I've tried many different cleaners in past but this worked so quickly and the different in mpg has shot up, knowing the engine is cleaner inside is massive piece of mind, attached pictures are before and after treatment on a mercedes c-class 2008 220 diesel
