(This is posted in the fuel economy thread as well, but I'm going to post it here for consistency. I'll be adding this ongoing to the OP at the top of this thread for now)

Filled up the first time this morning. Note that I do NOT know if this first tank was regular or premium. I was there when the dealer filled it up, but frankly didn't think to check. Since there is only one marking on the inside of the fuel cap cover that says Premium Fuel Only, I'm guessing it was Regular.

MPG over 308 miles was 29.38, mixed city/hwy, but probably a 65/35 split. Also included probably 10 to 15 minutes of total time at pure idle (showing people the car, listening to the engine, etc).

My city driving is a lot of stop and go, many stoplights.

My last DD had a 289K lifetime rating of 17.5MPG and used regular fuel. Based on that, on this one tank of gas, I've saved $20.77 over my last DD even with the price difference in fuel!

I'm a little disappointed the car does not have an Avg Speed display. My 2001 Astro (last DD) had that as well as Fuel Remaining. Avg. Speed over 289K miles was 35.7 on it.

I need to reverify this (seems lower than some others have reported) but on level road, my 6AT cruises at 2000RPM at 55MPH and 2250 RPM at 70MPH.
