Those are some of the CLEANEST plugs I've seen.
First, 11mpg arond town....do you have a lead foot? The most you would prolly expect around town is 17 or so. Heavy foot will KILL it.
You need to find somebody with a scan tool and check all the parameters of your sensors. Example: my s10 blazer (4.3) was running like shit, spitting out black smoke and stalling. Turned out to be a bad connector to the temp sensor....computer thought coolant was at -50 (open circuit reading), so it was running super rich.
Crap in, crap out....that's how computers work.
