05 Roadking plug discoloration

Not sure, smells like fuel but looks like oil? There were small modules on the plug edges. I think would be the best way to describe it. Thanks again

Fuel fouled would dry up if left out of the cylinder, oil fouled would look shiny .

Thanks again, it looks like oil deposits. I'll keep an eye on oil level and really appreciate the feed back. Like I said you guys are Great!
