I have 6700 on my es now and average 26.5. On highway only I'm getting 32....love it.

 

Thanks to everyone for their feedback! Hopefully, once the powertrain gets broke in, I'll see some improvement. For now I'll just stop sweating the price of fuel and enjoy the ride! Since I work at Toyota Motor Manufacturing, Kentucky (The home of Camry, Solara's & Avalons) on one hand I hate that the 350 is a nicer ride then my 01 Avalon.
