I absolutely agree with your post as I had heard of a dpf on diesel vehicles but not a gpf on petrol vehicles and the dealership never pointed it out or made me aware of it. I live in Wales and have 20 mph speed limits so it could be a nightmare except we have to visit our “local” hospital every few months which is 40 miles away so luckily by the time we are nearing the end of our journey it clears.
i add Redex and or Wynns fuel additive to try and ease the problem but still have the problem after a while. So much for reducing costs.
