It's not just the TL. All of the other cars that got the same highway mpg by Consumer Reports' drivers came in at 30 +/- 2 on the EPA highway test, with the Legacy the only one above 31.

That makes the 36 of the CVT Impreza (still interesting how many hyenas with manual transmissions are commenting on this thread) the hugely overoptimistic outlier.
First off, your reading comprehension is as bad as your math -- before the numbers were posted I predicted that those numbers were not the result of sustained highway driving at speeds faster than 65mph:

"Yes, pretty much spot on, you may have been running some winter gas blends during the trip, so that can account for some of the reduced mpg's.

What speeds were you driving it? If you were above 65mph for sustained driving that will also put you well outside the test parameters used by the EPA to derive the 36mpg figure.

Your mpg's are very similar to the real world (not spreadsheet) results other CVT drivers have been reporting, and far better than those reported by someone who drives his car at speeds over 75mph regularly..."

Given the reported speeds confirm my prediction, I expected you to congratulate rather than obfuscate, but that is too much to ask from a spreadsheet wunderkind.

I never said anything about his average speed, just that if his highway speeds were 65mph or lower his mpg's would be pretty good and potentially higher than he reported for his trip.

Was that too hard to understand?

PS Having an average mph of 50-55 indicates that this reported mileage was not all highway, or involved lots of stop and go traffic, if the car was driven between 55-65mph on cruise for a sustained highway drive, without the stop and go or side trips factored in, I would wager that the 36mpg would have been obtained, even with winter blend gas.
