Hi all, 

It's my first post here so please go easy on me! I've just collected a 2007 Nissan Navara which I think has a DPF problem, it's struggling under load when going up hills etc. I've found this article which outlines some of the best DPF cleaners to buy, has anybody used any of these and if so have they given good results?

Thanks in advance 

Hi....welcome to the Club

Generally, most cleaners are suitable to help break down the carbon but you would also need to drive it hard to build up the pressure which helps to blow out the soot.
Worst case scenario would be to get the DPF professionally cleaned and refitted which will almost certainly resolve the issue

Let us know how you get on with it
