My $.02 1) The EPA Fuel Economy Estimates are just that....Estimates. They are based on absolute perfect driving conditions: Not running the a/c, no head wind, perfect air temp and humidity; more or less a "perfect world", Which NOBODY lives in. 2) You are in California, California emmissions dramatically effect fuel mileage. also there really isn't a need to let the car "warm up" anymore, yes, I aggree you souldn't start the car up and slam it into gear, but rather start it, let the car reach idle speed and go from there. You need to keep in mind: 1) Compare apples to apples. You are no longer driving a 4-cyl small car. You now have a 6-cyl SUV, it has more weight and and 2 more hungry mouths to feed. On top of that being AWD 2 more wheel that at somepoint have power deliivered to them; more power used= less fuel mileage I do feel that your mileage does seem a bit on the low side, but not totally off the wall The Saturn Parts Guy It's just my opinion and only that, do with it want you must but don't flame me.
