#298 of 333 Re: Real time MPG [rickpoole] by dlake1 Nov 18, 2008 (6:04 am)
Replying to: rickpoole (Nov 18, 2008 5:21 am) Thanks. Too bad it's not instantaneous MPG. Acura should have it on the TL. One can gauge driving habits and try to "reform" and "refrain" from having too much fun accelerating . But it's also useful when cruising at constant speed.

With 800 miles on a '09 TL FWD I'm getting 19-20 mpg with roughly 50/50 city/highway driving.

Replying to: upstatedoc (Nov 10, 2008 1:21 pm) Leaving Sunday for Dallas (1200 miles each way) with 800 miles on the TL. I asked at the dealer about fast driving and they said 'no problem". I will post my MPG when I return.
#302 of 333 Actual MPG by rvator4 Dec 03, 2008 (12:40 pm)
Just back from a 2193 mile trip in a new 08 TL NAV base model. The on-board computer indicated 29, 30 and even 31 MPG for the entire trip. Actual MPG for the trip was 26.8, about 8% less than the 00 TL just 3 months ago(less HP). Miles on the car when we left was 876. Speeds were above the norm. Ran like a charm though. Did the return trip all in one day.
#303 of 333 variable mpg by zak_auto Dec 05, 2008 (12:53 pm)
I've had my '08 TL Type-S for a month now. On just highway driving around 75 MPH I get about 30-31 MPG. In a mix of highway & city driving I get about 26-27 MPG. With mostly city driving I get about 24 MPG. If I drive aggressively and mostly city driving I get a MPG in the low 20s. My last car was an RSX Type-S and the MPG didn't seem to jump around as much. The RSX was only a 4 cylinder though.

#305 of 333 Range Discrepancy? by ponderpoint Dec 25, 2008 (6:05 pm)
The yellow fuel low warning light came on and then I started watching "range/miles" left to empty. I thought I was excruciatingly close to running out of gas (10 miles to empty) when I pulled into the gas station.   I filled up the tank and it only took 14 gallons! Owners manual says 17 or so total and this obviously would mean you would have a LOT more range left than indicated on the computer (at least 60 miles by my driving habits).   Does anybody know if the range indication has issues with accuracy? Is it "pessimistic" to keep the motorist out of trouble (stranded) and have a dumb factor built in or is it really accurate? Any techies know anything about it? It's an 06 TL and I always reset the trip computer at fill-ups.   Thanks....

Replying to: ponderpoint (Dec 25, 2008 6:05 pm) '05 TL, same deal. I learned early on that the low fuel warning light comes on, well, early on... Better safe than walking...
#307 of 333 Re: How does TL calculate avg mpg? [dlake1] by rickpoole Jan 03, 2009 (8:46 pm)
Replying to: dlake1 (Nov 19, 2008 9:22 pm) The most explanation I've gotten is the computation is mostly based on manifold pressure. Seems like it would take a minor software update to make it much more accurate. But, I wonder how many sales they would have lost if it was accurate. I test drove the 07 TL three times in different traffic, different speeds, and different driving styles. Driving normally to conservatively resulted in a reading of 21-24 mpg and driving aggressively resulted in only 18 mpg . Given the inaccuracy it meant it really got 19-22 and 16. Given my requirement was no less than 20 mpg city it would have put the purchase in jeopardy unless the final price was lower to compensate for the lower mileage.
