On back roads with both transmissions in high gear, the manual gets somewhat better MPG. Of course, going over mountain passes, the manual gets about 6% better MPG. With its lower gearing, the manual has much better acceleration & speed holding ability on mountain slopes.
Good to know, thank you for the information! I suspect that the manual transmission gets better highway MPG because it is more mechanically efficient than the auto since it has less moving parts and no internal oil pump.
