There's oil on the threads, that's just me putting oil on them to stop them from seizing. But is the brown/black stuff on the centre electrode insulator considered fouled. I took a look at my other set of old plugs and the centre electrode insulator is whiter than my teeth.

This time its different. Do I have a problem with my motor? I have noticed that fuel economy hasn't been very good lately.
