hello there been a member for a long time now, this is my first post.
fiat panda engine 188A4000 1.2 dynamic, is this port or direct injection ?.
reason i would like to know is, if "snakeoil" additive would help clean the back of the valves.

Feed it with posh petrol such as Shell Optimax and you wont need to worry about cleaning valves etc. The total cost will be zero because the better quality fuel actually costs less per mile than "cheap" 95 RON.
