Sienna Bad MPG
Has anyone else gotten an average gas mileage of 14.5 with some city and mostly highway driving? If so, do you have the 17inch wheels? I've talked with other friends of mine who get between 18-20 MPG city but they have the 16 inch wheels. Maybe there is a miscalculation in the car's ECU because it is set up to display miles driven(odometer) based on the 16 inch tire----throwing of the odometer, speedometer, shift points(mine hunts alot in 5th gear on the highway!!), etc......
