Accuracy of "Miles to Empty?"

Accuracy of "Miles to Empty?"
Hello All.
I was wondering how accurate the "miles to empty" notation on the trip computer is? It always seems that when I fill the tank it takes far less than the maximum capacity. Is the miles to empty just how much is in there before going to reserve?
Can you drive it down to 0 miles to empty and still be safe?

TL is designed to be at ~3 Gallons of "reserve" gas when the Trip Computer says "0". Like Beats said, it is very consistent.
Look in your owners manual regarding the Temp Readout. It uses a goofy algorithm to set the temp - it is not a continous direct reading. Some have said the "true purpose" of the temp is so you know when the road temp is close to freezing and can adapt as needed for the possibilty of ice.

My "miles to empty" used to be 434 now for the past six months it has been 232 which is the right mileage that I have been getting out of a full tank.
My temp. sensor has already been changed by Acura twice, and it is still, sometimes, up to 17 degrees warmer than outside. Makes a big problem in winter when the temp outside is 50, the temp shows 67, and the I get AC with cold air instead of the heater.

also depends on how your driving u wanna hear vtec, driving in the city, out of the city... when I drive to NY or Fl im getting 31MPG at 80mph in cruise and it says >468 miles to go. I also have the AEM CAI and throttle body spacers. I thought it would give it less milage but it doesnt it keeps it really nice n high.

You can adjust that acuracyas well...
When you go into the Navi DIAG screens, you'll see the +40 mile buffer in the range screen. You can raise or lower that buffer and make it whatever you want.

It's safe to say one can run at least 50 miles after the fuel light is on ... on my type-s, that will show about 30 miles to ZERO ... I know that's a bit conservative cuz I've had it run over the nil limit a few times ...

AFTER Zero you can go an additional ~50 more miles (3 gallons).
So, from the time the fuel light comes on you can go ~75 - 100 miles (whatever you get on ~4 Gallons).
Past that, you're on your own .... walking. lol

Yes, the TL does have a very conservative fuel gauge.
I have run it consistently 70 miles beyond when the yellow low fuel light comes on.
I'm not sure how far I've run consistently beyond the 0 miles left indicator; but I know that the yellow low fuel light comes on before there's 0 miles left.
Even when I have driven 70 miles past the Fuel Light, the most gas I have put in is 16.1 gallons (tank capacity is 17.5 per the owner's manual).

this has been talked about alot before. all the details above are true, however i would not recommend driving on that reserve fuel because it is old dirty fuel left over from all the times you have filled up. but hey, if you need to drive it'll still work.
just some tips i read somewhere while were on the subject of gas:
if you always fill your tank up when you get to a half a tank you get more mileage out of your gas because this is the point when some of the fuel becomes vapor.
never fill up when you see a fuel truck at the gas station because this is when they are refilling the gas tanks and chances are that you are going to get the "bottom of the barrel" as far as the quality of gas you'll get.
never fill up when it is hot outside because more of the gas will become vapor than if you fill up when its cold.
and finally when you are pumping gas and you set the handle to where it fills without you needing to hold it, always put it on the middle or lowest setting because less of the fuel turns into vapor. the faster you pump the more vapor which gets recycled back into the pump and you get less gas.
sorry got a little carried away haha , hope that helped though.

LOL. I think that's a compliment. I guess some of my "dumber" posts didn't surprise you? (j/k )
Did you say that? If not, I bet you knew it.
Makes sense to me given two facts:
- The sensor is in the lower part of the bumper - relativley close to the road;
- Calibration of the unit includes using Ice Water to set the readout to 32*.

Are you worried to wait until the MID indicates "RANGE = 0" ??? (click here)
Outside Temperature Indicator Logic Explained (click here)
The A/C, the solar blocking glass, and the heater do
such a good job keeping the temperature of the
passenger’s compartment at a comfortable level that
it’s easy to lose track of just how hot or cold it really is
outside. An outside temperature indicator in the
gauge assembly gives you a reality check. But keep
in mind, this indicator isn’t a laboratory-grade
thermometer, and it might not show the same
temperature as you’d see on signs or buildings with
outside temp displays.
The outside air temperature sensor is mounted
behind the middle of the front bumper. The gauge
control module uses measurements from that sensor
to display the outside air temperature.
Because of where the sensor is mounted, it may be
affected by heat coming off the road, the engine, the
radiator, or even the exhaust pipes from other
vehicles. To minimize bogus readings, the gauge
control module follows a certain logic. Here’s how
that logic works:
When you turn the ignition switch to ON (II). . .
• If the engine coolant temperature is 139°F or
lower, the indicator shows the current outside air
temperature.
• If the engine coolant temperature is 140°F or
higher, the indicator shows the temperature that
was stored in memory when you turned the
ignition switch to LOCK (0), no matter what the
sensor behind the bumper currently measures.
The indicator doesn’t refresh until certain criteria are
met:
• If the measured outside air temperature is more
than the indicated temperature, the indicated
temperature rises 1°F every minute once the
vehicle reaches and maintains a speed of 19
mph or faster for at least 30 seconds. As long
as the vehicle speed doesn’t drop below that, the
indicator refreshes every 60 seconds until the
two temperatures match. If the vehicle speed
drops below 19 mph, the indicator doesn’t start to
refresh again until the vehicle speed climbs to 19
mph or faster for more than
90 seconds.
• If the measured outside air temperature is less
than the indicated temperature, the indicated
temperature drops 1°F every
2 seconds until the two temperatures match, no
matter what the vehicle speed is.
So here’s the bottom line: The outside temperature
indicator seldom delivers readings in real time
because of the many heat sources that could throw
off that indication.

When my light comes on, it takes about 13 gallons to fill. Since it's a 17 gallon tank there still should be at least another 60 miles for you to live on the edge before you start to worry.
My temp gauge seems to be pretty accurate measuring like geeky w the banks and stuff

It's obvious that every car seems to report miles to empty differently
Here are the last few fill-ups in mine:
Mi 2 empty Light On Gals Pumped Distance Traveled MPH
??? Yes 15 318 26
27 No 14.1 324 27
???? No 13.6 305 25
37 No 14.22 325 28
40 Yes 14.0 326 27
62 No 14 295 26
91 No 13.1 310 28
I've been keeping track so that when I change to synthetics I will be able to tell if there is a difference in milage.
Just noticed the spacing didn't format properly.
There are 5 columns
