Thanks!! I refilled the tank this morning and set the mpg screen to zero, and I'm now seeing over 31 miles per gallon. I'm thinking that the dealership didn't really "fill" the tank, and that the mileage reflected a few test drives before I purchased the car on Saturday. So far, I really love this vehicle. It's not loaded (no Nav system and such), but the leather interior is lovely and, most importantly, the gas mileage is now what I expected!!

Thanks for your help so far!
