Prius 3 Location: Albuquerque, NM Elevation: Mile High Car reported about 20 miles left on the tank. Filled it up with 9.55 Gallons - 455 miles = 47.70 MPG. The computer reported 49.9 MPG, FWIW. Weather was warm and now coldish. Drove the car 60 miles home on the freeway hauling nice person (gotta break the motor in ). Since then, been mainly drive in Eco mode. thoughts?
