Dealer states the car is normal, also there are no check engine lights.

Probable things to do/check:

1)Tire pressure, I set them all to factory specs but I can check it again.
2) Air filter(Dealer states it doesn't need to be changed, Indy states air filter is probably not the cause).
3) Clean the MAF.
4) Some fuel sysem or intake cleaner?
5) Ask dealer to check o2 sensors if the voltages are correct.


Any tips or opinions would be greatly appreciated.
I put 1 bottle of TECHRON in a full tank every 3000 miles or so. It cleans out my injectors and seems to help my fuel mileage marginally. Maybe for you it will clean out your injectors and give you a much needed improvement. I buy mine at my local AutoZone but here is what it looks like.
