Oil distributing problem?

What is your question?

I just got a oil change literally 2 days ago and it was running fine the day of, today when I drove my car it felt as if I never got one. When getting a tune up the mechanic said that the oil I guess isn't distributing evenly between spark plugs.. some would be very oily when taken out and some dry. What could be causing this problem. I also replaced all my spark plugs and coil packs about a month ago. The
