Pulled my #8 spark plug today just for the hell of it and it didn't look as good as I thought it would. There was oil on the threads and the tip although not too bad was like charcoal. Any thoughts? I've never had a check engine light or misfire codes. It runs good, no smoke.
Decided to check #8 spark plug just cause oil on threads don't tell me!!!

Need pics. Oil on the threads is normal.

Dumb I know, I took this with my iPhone and can't paste it directly from my album so above is the best I got for now.

Yea, its not working. Go to photobucket or something of the sort.
The inside of the spark plug porcelain should be paperbag brown, but you're not going to get a good idea of your plug condition with the car just idling. IE turning off the car from driving it or letting it sit in the drive way. Best thing to do is do a WOT throttle run as best you can, shut the engine off safely, then roll to a stop and pull the plug. You don't have to be in 5th gear 100MPH+, 1st gear is fine. I did mine this way and it was just as I described.

What 302 said.
Oil on the threads is normal. When you say "on the tip", I assume you are talking about the ground strap. This is also pretty common because most people scrape the tip of the plug pulling it out or, the plug drops out of the socket and oil gets on the tip. Pics would really help.

Did you compare it to the other plugs.... lol
No, but this I was told is bad. I get really paranoid when it comes to this #8 sh$t.

Dude, take a picture of the inside of the plug not the ground strap. Do a real plug run, and if you're real scared just datalog the car and send it to your tuner. If your tuner blows you off, return the vehicle back to stock and leave it or find a better tuner. Honestly, there was a thread posted here of a fouled #8 plug and that looks no where near like it. I think gig4fun was the OP of the thread. I know the OP was a mod and it was in 5.0L performance where others along with myself posted their #8 plugs. Just do a stare and compare.

It looks fine to me. I am surprised that you're so alarmed.

looks fine to me, Im sure others will chime in but youre being paranoid
I'm sure I am being paranoid. This is the favorite car I've owned, the most expensive and the one with the most bullsh$it associated with it. Oil consumption after 10k miles, engine rattles, knocks, fear of modding to not blow motor up. I'm not complaining, and I know everytime I ask a question regarding this engine I automatically don a flamesuit. I do appreciate the help and reassurance.
