The spark plugs I pulled out (in the pic) only have about 7k on them. I just replaced them last spring.
Just check if the single spark plug is consistently getting extra soot or if it's a temporary problem. It may be temporary due to Murphy's law, but it may also indicate that there is a small oil leak or a faulty injector in that cylinder.

Just a curious question? Why so many different threads on the same subject?
