The difference between what you're citing and my experience is pretty big (17-18 vs 22-23). 5 MPG seems a pretty big difference to account for with just a stick.

Could it be that your 2.7T wasn't getting optimal mileage? Or maybe you're not driving as aggressively as you used to (Jr. on board more often)?

When we've done MPG polls on the forum, there appears to be a pretty consistent advantage for the 2.7T by about 4 or 5 MPG. Not huge, but as a percentage, it's a non trivial increase. Your thoughts?
