#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.

Replying to: drmike (Jul 20, 2008 4:01 pm) Have run 1 and 1/2 tanks through tl we bought on July 14 using premium fuel. averaging about 21 mpg (hand calculated). My wifes daily commute is about 50% highway and 50% city streets. Also the first tank had quite a few "fun" runs with me behind the wheel. The computer said 23 MPG, but it got zeroed out about 50 miles into the 1st tank, after I stopped driving it.
#283 of 333 2008 TL-S Mileage by otisnj Aug 03, 2008 (5:53 am)
4700 miles on my TL-S - I just drove 640 miles up to Vermont and back - cruise was set at 70 MPH with A/C running - and averaged 30.4 miles per gallon   I am amazed.

Just over 16000 km (10,000 miles) on my 07 type s, it spends 70% of it's time doing 5 minute stop and go across town, the other 30% on 2 to 3 hour runs across the flat prairie at 110 km/h (65 mph). We get about 4 months of over 25C. about 5 months of 0 to 25C and the rest at -10 to -35C. Lifetime mpg imperial is 24 (29 US mpg). Pretty good considering my extreme climate and excessive town driving

Just bought TL 05 36k miles. Here's what i got, based on computer readings. City -> 18-20 MPG Highway w AC -> 30-31 75mph Highway w/o AC -> 30 80mph The car is real deal!!!!

Replying to: drmike (Jul 20, 2008 4:01 pm) As drmike says the trip computer is not reliable in calculating real mileage. I've had my 07 TL for 18 months and the trip computer typically reads 8-10% higher than actual mileage. To even out the tank to tank discrepancies I keep a running average of the last 4 tanks/trip computer readings. No one at the dealership or at Acura has been able to explain the poor accuracy.
