#259 of 333 Re: 2007 TL MPG [lockgiants] by rickpoole Mar 23, 2008 (6:25 pm)
Replying to: lockgiants (Mar 23, 2008 5:05 pm) I've been doing a series of tests over the past couple of months since my mileage seems to vary quite a bit driving to and from work. Fortunately I have a short drive, less than 4 miles, and it stands to reason that when it was colder I would get worse mileage since the car would barely have time to warm up before the end of the trip. The drive time to and from work is almost always about 15 minutes usually with stopping at 3 lights and averaging 40-45 mph. I was resetting the trip computer before leaving the house or work and seeing what it read at the end of the trip. What the dealer can't explain is why it varies so much. When it was 35-45 degrees I was averaging 12-13 mpg in the morning and 22-24 mpg in the afternoon. If it always got 12-13 mpg in the morning it would seem that it just uses a lot more gas when warming up. But, on a few mornings I got 18 mpg with about the same drive time and stopping at the same lights. Because all the sensors are ignored while the engine is warming up there is no easy way to tell if it is sometimes using way too much gas during warmup. Based on my research most fuel injected engines use 15-20% more gas during warmup. My tests show it uses as much as 50% more. For the past week I've been letting it idle for 2-3 minutes before leaving in the morning and the mileage has gone up by 2 mpg. Acura can't explain it and would not provide the designed warmup gas consumption information so there is no way of knowing if it is operating as designed. My dealer has agreed to swap for a 2008 TL for a week or two so I can do the same tests with another car (they couldn't locate another 2007 TL). BTW - now that it's warmer I've been averaging 19-21 in the morning and still 22-24 in the afternoons (still not hot enough to start using the A/C) so this test may have to wait until next winter.

Replying to: rickpoole (Mar 23, 2008 6:25 pm) Our 2000 TL that we bought new now has 67K miles after a 2500 mile trip. I like to drive very fast on vacations and this trip was no exception with speeds reaching nearly to the triple digits at times. The trip was over 2400 miles and this awesome car averaged 29.95 MPG. I use the mid grade fuel all the time. I put new Goodyear tires on it about a year ago and before leaving, made sure the air was right on. I have never replaced the air filter but I blow it out with compressed air every month. It also has the original plugs. The car has never been to the Acura dealer for any maintenance except for a tranny mod recall. Other than regular oil changes at the local Honda garage and myself installing new Brembo brake rotors, the car has had zero maintenance costs.
#261 of 333 I feel sorry for you owners.. of which I am one! by scottc3 Apr 23, 2008 (7:27 pm)
My wife (and of course I) recently bought a 08 TL. She drives it and pays for the gas!! I bought an 08 Prius.. and love the car. It's not a TL for sure, but has many features I like. I read these posts and can only feel sorry for us (all). It's only going to get worse. In the mean time, I'm getting about 50 mpg on the Prius.. take a look sometime - you might like the Prius too.   sc
#262 of 333 Road Trip! by laurasdada Apr 28, 2008 (9:12 am)
Back from our week in Washington, DC. For those that have not visited our nation's capitol, I highly recommend a visit. Totals from roundtrip from south of Boston to DC area, four people and very full trunk!:   Miles: 1124 85% highway, 15% local. Including traffic jams on the way, back and on the Outer Loop (I495) Avg. MPH: 49 Avg. MPG: 27   TL was flawless, but now pollen and dirt covered... "Cheapest" gas in NJ.

Greetings! Just back from a road trip/family vacation to Washingmachine, DC. TL was flawless, packed to the gills with the four of us and detritus, encountering several traffic jams and some local driving, drove 1124 miles and averaged 49mph and 27 mpg.   I'm sure y'all have been, but if not, I most highly recommend a trip to our Nation's Capitol. If nothing else, it reminded/reinforced that the idea, conception, governmental model and ideals of this country are just so right. I'll leave the execution of our ideals throughout history to your discussion. Where is George Washington when we need him? A nation turns its lonely eyes to you...   Toured the Capitol Building, sat in the House Gallery and was entertained by a Representative from the Great State of South Carolina. Thank you, Rep. Barrett for a fun, enlightening time. Watched a resolution presented and objected to regarding The Delta Queen. Kids were getting fidgety, so had to leave before all the yeas and nays were tallied, it was a close race. Fabulous tour guide, Albert Caswell the "unofficial Poet Laureate" of the Capitol.   Also, rode to the top of the Washington Monument, toured the Bureau of Engraving and Printing ("The buck starts here!") several Smithsonian Museums, showed the kids the White House.   I had two very emotional moments, chilling, prideful, patriotic, depressing, scary...:   First was at the National Air and Space Museum at Dulles Airport. Go, do not miss this museum! One section of the museum was dominated by a large, familiar looking, shiny metal aircraft. As I drew closer, I noted the name: THE Enola Gay. Stopped me in my tracks, as a cold shudder engulfed my body. A show-stopper for me...   The Second was the Vietnam Memorial. Crowded, beautiful, chilling, depressing, stunning, reverant. I would imagine any Baby-Boomer would have such feelings. I looked through the index for the name of my summer camp counselor who, if memory servers, received a draft number in the 30s that summer oh so long ago. To this day, I remember his name, the look on his face when he received his number. Much to my relief, his name was not on the wall. "Tin soldiers and Nixon coming, we're finally on our own..."   Also visited the WWII and Korean monuments which were also sobering, but Vietnam was, unfortunately, "my war." Stopped in front of the IRS building and booed rather loudly.   Stayed in Landover, MD. Took the T, I mean Metro, into the city daily. A relatively clean, efficient subway system. One funny note: Each day the Metro would go by RFK stadium just before going underground. ONe day it appeared that there was a tractor-trailer school training future 18-wheel drivers in the parking lot of RFK. The next day, one of the very tall light towers was on the ground in that same parking lot, no sign of the tractor-trailer folks!   Great vacation, so much to see and do. Almost all free, but you do need tickets for the Washington Monument tour, Capitol and Bureau of Engraving. All worth it.   Go, even if you've gone before.

Replying to: laurasdada (Apr 28, 2008 1:19 pm) LD, Great post, I have a buddy who lives an hour away from D.C.(who happens to own an '05 TL!) and the last time we saw him we took a trip into the city. Visited most of the sites you did. It truly is awe inspiring to see some of these sites in person that maybe you've only seen on TV. My wife had never been. Now you've got me jones'en to go again!

Replying to: laurasdada (Apr 28, 2008 1:19 pm) Thanks for the travelogue!   I visited the National Zoo and really enjoyed it. The Pandas are amazing. Replies to this message: laurasdada (Apr 29, 2008 1:22 pm)

Replying to: upstatedoc (Apr 29, 2008 4:40 am) Go, Doc. I could go back tomorrow (as we didn't make it to the Zoo or Arlington. Went to Arlington with my family as a youth, I still remember the silence and my mother's tears at JFK's grave...). Just being in DC kinda renewed my faith in this country after watching too much, ad nausuem, TV news regarding the upcoming elections. Again, the ideals of this great country are ideal...   Make sure you visit the Air/Space Museum at Dulles...

Replying to: aaargh (Apr 29, 2008 7:03 am) Didn't make the Zoo. One of many reasons to return. I'm sure the kids would come home with stuffed Panda dolls!
#268 of 333 Accuracy of mileage computer by hicow May 13, 2008 (3:29 am)
I have a 2007 TL with about 7,000 miles. I've been calculating my mileage manually and also monitoring the computer. The computer has been consistently showing 2 MPG better than the actual mileage. That's until the last fill when the computer showed 2 MPG worse than the actual calculated. The only change has been the weather which is warmer now. Anyone else experience this fluctuation?   The best highway mileage so far is 32 when I set the speed control at 70. Replies to this message: rickpoole (May 13, 2008 8:21 pm)
