Good additive but don't overuse!
Recommended to me by a mechanic and this was the best deal for me on eBay. Product seems to work fine but only use it every two months or so. Overuse can be detremental. It cleans the vital parts of the engine to ensure continued efficiency.It is NOT meant to be a replacement for the regular service that any engine needs

Good product
Have to say, Didn't think it would work. I got 6 bottles, and glad did. By 5 and 6 could really notice the difference in start up and running. Much less smoke in both situations.
With that also came better throttle response. the car was defiantly more eager to accelerate with less foot down.
Given that, I think i'll be saving on fuel also. Although not sure how much just yet. Intend to use this going forward every two to three fill ups to keep the benefits achieved and keep the fuel system tip top.
Try it.
My vehicle was sluggish, Smokey and a pain in traffic. Now a lot smoother and even sounds better.
Good move. Read full review...

Great Product
Engine runs smoother and cleans up emissions nicely. Also improvement in economy which offsets the cost of the product. Good stuff.

Comma Diesel Magic
Great product which I’ve used many times on numerous vehicles. You can really notice a difference in performance and it should also be keeping the injectors and fuel lines clean and free of dirt.
Well packaged and at a competitive price compared to car accessory shops. Read full review...

Honest review
I have seen alot of reviews and was not to sure. But i can honestly say this has helped. I would only use with 30 to 35ltr of fuel and no more. It is a good size and great value 5*****

Will buy again
Really makes a big difference to my Vivaro 1.9 di, gives a much better pull uphill and feels much less lethargic.
Highly recommended and cheaper than my previous tipple Millers eco max.

It's worth buying
I did notice a difference in the sound of my engine when using this, I do plan to make using this as a routine, but it wasn't able to resolve the engine issues that I'm dealing with currently, maybe if I was using this product sooner, I wouldn't have developed injector problems?Read full review...

Magical addictive
This product revitalised my 13-year-old car. It runs like a sewing machine. The postage was also incredibly fast. I am one happy customer who will always buy this product for my car
