Yeah I'm losing oil, but that is--so far as I know--only b/c of front main seal leak. Will check to see if residue oily.I think its not terrible, but not great.
I agree it looks a bit sooty / carbonised.
Also think it could be a bit of oil being burnt. Are you losing oil? Or seeing any blue smoke in the exhaust.
How many miles on your engine?
Mine was burning oil, and ready for valve stern seals at 200k km (130ish miles)
If it's burning oil, the sooty residue on the plug might have an oily consistency if you rub it
