Something is robbing my MPGs!?

[OCDjG]

:UPDATE:

OK so I've replaced my PCV valve, re-checked the pressure on my tires, and I ran a fuel injector cleaner through my gas tank and I have now regained some lost mpgs! I can't say how many just yet since I'm still not on "E" yet, but there is a considerable difference. Anyone that has not done this and they have a lot of miles on your car I strongly recommend doing these things. These are all cheap maintainences you can do yourself.

When I put my body kit on, I got better MPG. Something to think about

My carbon fiber gas lid gained me 6 mpgs because of the lighter weight.

I think I'm robbing my car of MPGs.

I'm a little husky.
