Purchased a new TL in April this year. It is one of my wife's daily drivers and is our trip car. So far we have put about 6500 miles on it. We record every bit of fuel and the corresponding distance every time we fill it. Overall, we are getting 28.3 miles per gallon. On interstates (no stop and go whatsoever) we get about 34 mpg driving 68-71 mph. The mpg figures cited above are actual calculations and do not come from the onboard computer which is a little flattering when it comes to fuel mileage. Our local driving is a mix of limited access highways and stop and go town driving. Needless to say, we are happy with the fuel mileage we are getting.

We use 93 octane fuel in it, and I keep tires about 2 psi over what is recommended.
