Winter gas, having an automatic, having a fuel leak which would explain the smell, had the pump recall done? Driving 10-15 under the speed limit actually wouldn't help, I want to say you get the best MPG at 45 MPH.
You're getting about 21 MPG which makes sense for many short drives, engine is most efficient when fully warmed up and uses more gas until fully warmed up. Mostly city driving and that's where it should be.
