I took my plugs out today to look at them and this is what they looked like. I don't know if these indicate how my car is running or if I am really running rich or lean or not?

Looking at these plugs the corresponding cylinder is 4-3-2-1. When I pulled plugs 1 & 4 out there was oil on the outer cases and I don't know what to make of this. There is no oil on the inside tubes where the spark plugs are held but it doesn't seem like it is leaking anywhere. I am thinking this may be left over oil from my bad/old valve cover gasket. If not.. Head gasket?

Are the side electrodes supposed to look white like this?

Now I know that I have not had these spark plugs in for even a 1000 miles yet but if it is possible to tell if I am running rich or lean or normal I can get some things out of the way to move on to other things I can think of that are making my car misfire so much and crap out at 4grand.

Somewhere/something that is making my car run so bad is only allowing me to get a whopping 18mpg while babying it.
