Kind of weird to fill up and not spend much more than $30, isn't it? Car can get higher than that with little miles. I hit 53 MPG on my 40 mile ride from the dealership when I picked my car up. It's all about your driving style, acceleration and speed.
I pick up mine 2 weeks ago. I drove it for awhile and got 44 on my first tank - ALTHOUGH - I find I can get in the 50 pretty easily if I try to drive easy. My wife drives it 75% more than I do. Together we have been getting 46... (she has a lead foot and likes the SPORT mode...). I only have 900 miles on it so far. Eithway its better than the 20 I get on my Highlander.
