Diesel High Milage Injector Cleaner 200 ml, Cleans and Protects your Engine for 300 miles, Enhances Fuel Economy, Mechanical Car Cleaning Products, Concentrated Cleaning Formula, Made in the UK

Did the job perfectly. I have only used one of the bottles so far. My diesel engine started running a bit rough and felt like she might cut out when I was stationary at junctions. She's an old Kia Sorento. I figured before I booked her in for exploratory work, I'd add the bottle to my next tank of diesel and it worked. One day, when I put my foot down hard, I could see a puff of black smoke come out of the back of the car (after I'd used this additive) and have not had a problem since. I think it cleared whatever gunk was in the fuel system. I'll be using the second bottle in about 6 months time. I used the Diesel Injector cleaner first. I'll use the Diesel System cleaner next. Good price and super fast delivery. I've only used the injector cleaner so far and driven around 100 miles but the fuel economy has definitely increased and the engine noise has gotten quieter so i'm happy to recommend.

Yes I thought I’m going to give them a try this time and I diverted to this product and I’m glad I did it has got to work and a huge difference in what 10 miles I started noticing the acceleration levelled in response to my foot instead of struggling I now after a week have a vehicle that runs pulls good and is responsive again easy to use a cheap way to solve further headaches if left I will be using every 2900 miles as I have high mileage

My Vauxhall has frequently DPF troubles. I used this once and felt the acceleration improved substantially. I thinks this works on the injector as said and will buy the system cleaner later to keep my car away from the warning DPF light.

Instant effect noticed when added to fuel tank. Recommended for diesel engines every 3-6 months to avoid blocked dpf problems - if not included in your annual service, add it yourself.

Magic stuff. I'm dubious of products like this because I know cars need looking after properly and there's no magic wand. I have an old diesel that's fast approaching 150k. It was running rough, down on power and idling all over. I thought I'd try this pre a service. Put it in with a full tank and honestly forgot I had. After about 50 miles it's back to normal. Beautiful idling, power back. I've decided to use this with every full tank going forward it's magic.

Within 10 miles i suddenly started feeling the car was driving smoother, it was amazing how in cold morning starts it started immediately when i turn the key, no jerkiness due to it being cold. Then i went on a 100-mile trip the day after I put it in the tank, and my MPG exploded, i even had a game with the kids to see if i could get it higher, while keeping up with traffic, and reached 54 MPG at one point but, that was with a bit of neutral on long hills, not much mind you, there was a lot of stop starting as well. After a few days of normal driving I now am running at 48mpg, it is something i have never experienced in my car since I bought it 7 years ago, it has constantly been running at around 28mpg , 2007 ,model ford galaxy 2.0tdci. For those that use km a liter that is around 18km per liter I think if this lasts a while, i am going to put in a bottle every third tank of fuel.

My 140k Miles BMW 5 series went quite only after 100 miles or so. Improved mileage and pickup.

I've been using this in my car for 9 months now and cannot say I notice any difference. It might run slightly smoother but no difference in MPG or build up of carbon in the EGR valve. Still struggled to pass the emissions test too. So disappointed with the results od a long term test.

Ho una vettura con 300.000 km ed ho voluto provare. Piccolo investimento ! 😀

Aunque se equivocaron en el envío se solucionó rápidamente. El producto muy bien. Cuando lo puse en el depósito al los pocos kilómetros se notaba como el coche iba con más fluidez, más "alegría" teniendo en cuenta que son más de trescientos mil kilómetros.
