I have a 2009 TL w/Tech with about 3100 miles. Per the trip computer I have gotten 23.2 mpg over the 3100 miles. I would say you should expect 25-26 on strictly highway driving and 21-22 for city driving.

how fast do you usually go? I try to go around 65 MPH to get the maximum gas mileage.

Just returned from a 400 mile round trip on two lane highways. Used cruise most of the trip set at 61. OBC totaled 32.5 mpg when I pulled home into the garage with our 09 TL with tech. Very happy with it after 6000 miles.

I had a 2009 TL w/tech for over a week while my 2007 TL was in the shop. Most of the driving was the same city driving I do in my 2007 TL and the computed mileage (miles driven / gallons used) was actually lower than my TL (18 versus 20). All the city driving was conservative - gentle acceleration, letting the car slow down normally versus maintaining speed up to red lights, etc. I expected slightly better mileage from the 2009 since they are both rated at 18 city but the 2007 rating were about 10-20% high and the 2009 ratings are supposed to be much closer to actual driving. I only got to drive about 60 highway miles and it averaged about 2 mpg less than my 2007 TL (26 versus 28). Mileage computer always showed about 10% higher than actual (which is about the same as my 2007 TL). The one thing I could never get a clear answer to was whether the dealer's loaner cars were filled with regular or premium. Based on how much acceleration the 2009 TL had I'd be surprised if it was filled with regular (my 2007 TL shows a noticeable drop in acceleration if filled with regular). Since I didn't get to refill it from near empty I also didn't get to test whether a complete ECU reset like I do on my 2007 TL every few fillups helps improve the mileage.

To verify the OBC on this trip, I check actual miles to actual gas at fill up. Came in a 33 mpg. My wife has been getting around 25 mpg with mix of small city and highway.
#322 of 365 2008 TL Gas Mileage

I drive a base 2008 TL and am getting about 24mpg city and about 27-28 mpg on the highway; I consider these excellent numbers for a luxury sports sedan like the TL; the only other luxury sedan that gets good numbers like this is the ES350 buts thats not a sports sedan; infiniti, BMW, or audi doesn't get numbers like this!!!

2009 TL with Tech with 4,500 miles averaged 26.5 mpg on last tankful per the on board computer. Best results yet. Primarily 400 highway miles for this tank. Although, my wife drove a few of the miles and I suspect she was driving a little slower than I do. Pleasantly surprised at 26.5mpg.
#324 of 365 2008 Base TL Premium Gas Issue
Aug 03, 2009 (5:47 pm)
I drive a 2008 Base TL and have been using Hess 93 Octane gas for the last year; I've been getting a respectable 24 MPG with mostly rural town/city driving and about 28-29 MPG with highway/interstate travel; over the last two months I switched to Shell V-power after reading several articles on Edmunds, etc how Shell is a top tier fuel and they most people get their best gas mileage with them but I don't see that happening with me; I've had 6 fill ups with Shell V-power and have lost 2 MPG in all driving; I now get 22 MPG with mostly rural town/city driving and about 25-26 MPG with highway/interstate travel; has anyone else had this happen to them? I was going to give it another two fillups with Shell V-Power to see if the MPG improves but if it doesn't I'm going to switch back to Hess/Exxon/BP 93 Octane

Not with Hess/Shell but with Racetrack/Chevron. I had been getting about 21 mpg mostly city driving (85% city, very conservatively driven) using Racetrack 93. But the last two fillups were at the same Chevron with 93 and mileage was down immediately - still 21 mpg but with 50% city (should have been around 24). Went back to Racetrack and after 1/2 a tank of 85% city it is currently at 22 (reading 24 but is always 8-10% high). While running the Chevron 93 it didn't seem to have as much power so it makes me wonder if their 93 tanks got filled with 87. According to local Acura dealership there is no way to determine this from the diagnostic equipment and a local lab says it would cost about $100 to run a test to determine the octane rating of a sample of gas.
