My GLA OM651 engine is much more smoother and I can say that trotle is more responsive specially on 1st to second gear no more lagging jerking. Also mpg restored back to normal.I will use it again from now on.

Seems to do exactly as it says on the bottle. Good stuff

I have used this Cataclean Diesel for the last years. It has been drawn to my attention that my emissions reading is lower than my neighbours 2018 reading on his. I use the petrol Cataclean in my wifes car anf my motorcycle too. Easy to poor with no spillage. Teriffic product

Put this in my lads peugeot 208 1.4 diesel because it was sluggish on acceleration upto 40 mph and in no time its radically improved. Also added it o my bmw 330d msport and again everythinn from acceleration to mpg has improved and that was with one bottle added will add again in a couple of tankfuls time

Hard to tell what difference it makes

This is a Diesel fuel tank addative for Diesel powered vehicles that have a DPF or Catalytic exhaust system, Im using this as a Preventative measure, and not an unblocking chemical.I've found this product to work, especially on a diesel powered vehicle that had a DPF warning light up. A friend had suffered this warning due to short journeys, but no more. It's doing the trick. Now I use this in my vehicle every third fill up, and I dont let my tank go below 1/3 rd full. In height of winter, I may increase its usage to every fillup, mainly due to cold weather, but we will see how we go. Thank you for the good deals on this product. It's a good one.

Have been using over the years and still do, good value for money and a very good item that sorts the car out.

good
