#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.

Replying to: ponderpoint (Dec 25, 2008 6:05 pm) Yes, it is very pessimistic. You do not want to foul the injectors with crud, so they want you to fill up well before empty.   This is the case for my '04 and I believe for every TL through '08.

Replying to: aaargh (Jan 05, 2009 9:23 am) "You do not want to foul the injectors with crud"   Well.... I guess that's why my mechanic says "NEVER EVER run out of fuel with a fuel injected car!!!! Thanks for the answer, I've pretty much concluded that there is range left when the computer is showing 10 or so miles. I'm not in the routine of getting that close anyway but it's nice to know in case of an emergency...

I have 2008 Type-S and over 12K miles am averaging 22.4, I had another 2008 Type-S before this one and avergaed 21.5 on that one. The differecne I think is the gas I use now. I used to use Chevron and Shell, great gas but I suspect numerous mom & pop statiosn are not real honest with calibrating their pumps. IOn this Type-S I use exclusevliy Quik Trip Premium and see better MPG all around. I have doen more HWY on this car, but tank by tank I still see at least .5 MPG better on Quick Trip. My 07 BAse TL with NAV over 11K miles averaged 22.5 MPG as well. I also only use Mobil1 5W20 Synthtic in my cars.
#312 of 333 Acura TL mileage by flanker0219 Feb 02, 2009 (5:05 pm)
Hi, I have an 08 TL with approx 2000 miles on it. I mostly drive in the city on roads where the average speed limit is about 40-45 mph. My trip computer shows 15 mpg - today I was observing the range and it dropped by about 20 miles when infact I had driven just about 11 miles. I am not an aggressive driver however most of my trips are short - I drive on an avg 15 miles/day. Should the fact I mostly drive on city roads for short trips bring down my mileage so much?

Replying to: flanker0219 (Feb 02, 2009 5:05 pm) Short trips are killers plan and simple, the car takes a few miles to warm up and until then the MPG is going to be off. In winter the warm up time is longer as the temp is colder. I drive 18 miles to work and at average back roads speed of 40-45 MPH with lights I get 24-25MPG on way to work as there is no traffic, same trip home with traffic I am lucky if I get 20-21MPG and the trip home takes 15 minutes longer due to traffic. Short trips of a few miles and I get horrible MPG. The GF has a CRV, gets 23 MPG on decent 18 mile commute for me, her commute is 6-7 miles and more traffic and she gets 19 MPG, car is warming up half the trip and then the traffic kills it.
#314 of 333 Long, fast trip in 3.2 TL by rvator4 Mar 11, 2009 (3:53 pm)
Just back from a 2338 mile trip in our 08 TL 3.2. Got 27.6 MPG. Same trip in November we got 26.8. First trip when we left had just 870 or so miles. This trip started with 3534 miles on car. Maybe it will continue to get better. Has a long way to go to match same trips in 00 3.2 TL where we got right at 30 MPG. Speed was very fast as usual. Before leaving I installed 3M clear protective covering myself and it worked great.
