#272 of 333 Re: 22 MPG on 2008 TL [zeen] by upstatedoc May 14, 2008 (12:09 pm)
Replying to: zeen (May 14, 2008 9:53 am) That sounds pretty low....   Do you have the type-s?   My '05 TL would consistently get 22mpg in mixed driving (mostly city)   When on the highway, what was your average speed?   When you say hilly do you mean Pike's Peak or the rolling hills of Kentucky?   Steep hills can certainly destroy gas mileage especially if you have a load in the car.   The last issue is gas grade, I used 93 in my TL. If you use less than 91 your mileage will suffer

Replying to: zeen (May 14, 2008 9:53 am) Just did round trip 300 miles each way, highway only 07 base TL 6000 miles and got 30 MPG by calculation, computer said 32 on the way down and 31 on the way back, 70-80 MPH. If you are getting 16 on the highway there is a problem. Old MIke Replies to this message: zeen (Jun 09, 2008 2:15 pm)

Replying to: mf15 (May 15, 2008 8:22 am) OK My mistake. Just did a 120 mile mostly highway trip and the computer had me at 33 mpg. I drove 65 or less and tried to stay at or under 2000 rpm. It was easy with the 6 speed transmission. Once you start doing local roads or accelerating rapidly, there is a sharp drop off in mpg. 33 is quite good and it wasn't hard.

Replying to: laurelmd (May 13, 2008 6:06 am) Up to my 7th tank, still doing about 22 MPG on mixed driving manual calculations. On last tank, I drove nearly 60 miles after low fuel light came on, and still only filled 14.8 gallons! With a 17.1 gallon tank, this easily suggests a range of over 100 miles after low fuel light comes on, which means it really isn't a low fuel light!   Do others have a similar experience with the low fuel light?

Replying to: laurelmd (Jun 09, 2008 6:24 pm) Yes, the low fuel light comes on very early. It has been this way since the '04s. Acura REALLY does not want you to run out of gas!   I think the issue is that if you do run out of gas, the setiment in the tank will get into the fuel injectors and really muck up the works. And with as highly tuned as these engines are, that would be very very bad. SO, better safe than sorry I guess.   To me it's no big deal. I doesn't matter whether I pay $50 (I wish) to fill up when it is really empty OR to pay $45 when it is has a few gallons left. I'm using the same amount of gas overall either way. Of course I am at the station a little more frequently, but that is not an issue to me.   In reality, I fill up between 1/4 and E. Occasionaly I delve into the murcky after-empty range, but not too far. It isn't important to me that I squeeze every last drop out of the tank.
#277 of 333 2007 TL mileage by miketl07 Jun 15, 2008 (1:49 pm)
Drove from KC to Omaha on first tank avg speed 62 mph (majority of 220 miles were highway) computer said 33mpg actually seemed to stop at 33mpg) filled up in town and manually calculated 35.11 mpg ( I was delighted to say the least). a few months later took a 120 mile round trip pretty much all highway, filled up before and after trip at same station in fact at same pump. Computer said 32MPG I manually calculated it at 26MPG. Average speed 55 mph. Weather conditions and road conditions nearly identical. Anyone else experience such a fluctuation before? I was careful to fill to full (as best you can) the same amount, again same station same pump and same pumper me of course.

Replying to: miketl07 (Jun 15, 2008 1:49 pm) I have a question; How the hell do you drive a TL at less than 70 on the freeway? My daily commute is about 22 miles, 16.5 or so is freeway and I average 80 but I have to pay attention because it wants to go faster. I try to keep the RPM 2750 on the freeway and under 5000 under acceleration. Even with an 80 mph freeway drive and "spirited" acceleration the rest of the time I still manage no less than 23 (manual calculation). I did one pure freeway jaunt after a fill up, maybe 40 miles and the computer showed 30 mpg at a steady 80. Right now the car's computer is still "optimistic" about the mileage but only by about 1 mpg now.   The car is a 2008 TL-S with 6M and 7000 miles. My mileage fluctuates very little, and mostly due to a change in my route. If I spend some time driving around town or make a trip to another city that I don't usually make, I can change the mileage but not by much. It rarely varies more than 1 mpg. I can't be happier with the car overall, it's the best of both worlds! Having this kind of performance, luxury and this kind of mileage? My previous car was 450 lbs lighter, 100 HP less and got WORSE mileage! Replies to this message: zeen (Jun 17, 2008 1:24 pm)

Replying to: chirocat (Jun 15, 2008 8:30 pm) I have an 08 auto. Drove about 110 miles and was able to keep the rpm around 2000 with the exception of coming out of a toll booth etc. Averaged 33. That's the key, but it's painful when you know you have this great engine.

Those of you not hand-calculating your mileage and relying on your vehicle's computer have no real idea of what mileage you are getting. Your on-board computer is not a reliable instrument in measuring mileage and shouldn't be counted upon to give an accurate reading.

Replying to: drmike (Jul 20, 2008 4:01 pm) I checked my calculated mileage against the car's computer a couple of times and was surprised that they were both the same.
