My guess is that on the highway, the Aero has a much more fuelefficient engine and its sleeker, more aerodynamic body comes into play. In low city speeds, the added weight over the 9000 and the aggressive cams and timing on the engine compared to the 9000 contributes to the overall mileage. Kristian
