Most of my driving is suburban traffic in the 30-60 mph range. If I shift at 4000-5500 rpm in the lower gears, which I generally do, I get get 15-17 mpg. If I keep the engine between 1500 and 2500 rpm, it jumps to high teens. Open highway at 75 mph on cruise control yields 20-21 mpg.
I also see 2-3 mpg difference between the real mileage and the ODC mileage. Doues anyone know how to "adjust" or calibrate the ODC?
