It worked a treat in my truck follow the guidelines on the back of the bottle..👍

Good quality

Does the job, even cleared management light for DPF depending on how bad it is may have to do a couple of times.

Had to have a sensor unblocked on quasqui 68 plate, man recommended this as additive, every three months, not happened again since, pricey seems to work, but should have bought petrol version...diesel Focus previously cost 000's to fix dpf issue and ultimately we buy any car it. Rant over, seems to work!

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

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.

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.

Hard to tell what difference it makes
