I was at HH last week getting my car MOT's and saw a few petrol cars being treated to this stuff, I enquired more about this and was advised this cleaner is approved by Honda. Its approved by Honda I have to try this out . I have been using BG44k on my wives car for some years now , just before a major service I dropped a can of this cleaner the results were good and the car felt good. However BG44K has change it formulation to to a Kerosene based cleaner. Anyone who know Kerosene is bad for piston bores and piston rings, however the concentration is so low the damage will be minimal but with repeated use it will make an affect. So why use a Kerosene based cleaner at all? when Tunap 973 is free from it and the best thing it is half the price of BG44K. Tunap also have a additive\cleaner which is approved for all DPF equipped vehicles. I have popped this both into my tourer and will remove the throttle bodies to reveal their effectiveness. If anyone is interested in buying this cleaner can contact HH they have a special offer at the moment for AOC members.
