The DPF cleaner cleared the carbon blockage in the DPF unit of my Ford transit connect van, choked up by doing short runs. I eventually used 2 bottles after calculating diesel content of fuel tank and went for a few longer trips with 3rd gear engaged to run at higher RPM 3000rpm. The fault warning icon on the instrument panel extinguished, an alarm chime sounded and I reset the engine block icon on the panel with my OBD2 diagnostic device with engine stopped. Van is now running well, power and speed restored , a good job done Thank You !!!

I've got a clunky old Nissan X Trail. More miles on it than The Starship Enterprise. Turbo gets a bit bogged down from time to time. Ran a bottle of this through a full tank of ultimate diesel followed by another with regular diesel and it's blown the soot right out. Pulls like a... well, a 2.2 litre 4x4 that's 15 years old but is at least a bit less sooty.

I've used JLM DPF (diesel particulate filter) cleaner previously at £25-26 for a 375ml bottle. Good product but so expensive. I paid £11.49 for this Wynn's job with free postage (AND it was posted from Northern Ireland) and it is just as good. Cleaned my DPF out no problem. The Focus diesel is ticking over lovely. It de-sooted the the DPF like it says on the label. I took it on a good run on the motorway averaging 1700-1800 revs and noticed the difference in performance quite quickly. I'd do about 100 miles at the same revs if you can for it to work its magic. For those out there not familiar with what a blocked DPF does to your cars performance a mechanic associate of mine summed it up as follows: Recite the alphabet whilst doing your best to strangle yourself. That's what a diesel engine feels like with a blocked DPF. A great way of explaining it I think. Overall, yes this is a good and value for money product. At this price I can afford to put a bottle in the fuel tank every couple of thousand miles as a preventative.Read full review

I use it infrequently but regularly and Wynns 77101 Formula Gold High Performance Engine Treatment 500ml Double Action because I only do short trips. Seems to keep my diesel engine in good condition. 10 years on - so far so good!
