Prodigit is joking. The dark stuff on the threads of the plug might be oil, but you read a plug at the electrode and porcelain insulator, NOT the threads. And that part of the plug looks pretty good. No reason to clean it with a wire brush! There is nothing there.
Your M is low miles. Over time the porcelain will discolor to off white. But if it gets a chaulky residue, too lean. If it gets sooty, too rich. Yours is neither. But I think that's a cheap Torch plug. Get a good plug in there. NGK DR8EA (7162) is a good one.
