In my new TL, it's got 2000 miles now, the fuel light comes on, but when I fill up the tank there's only room for around 13-14 gallons? The trip computer will say that I only have 20 miles left, but I think the tank holds 17 gallons, so where is the rest of the gasoline

Is the gas sensor off? Is that even a problem that exists in these cars?

I just feel like I got the gas station all the time, and would like to let it run a little bit more, but I don't want to be stranded. I have never ever put more than 14.5 gallons in the car even when it's completely empty.

 

I've noticed that my fuel light comes on at 2/8's the gauging and is not close to the red line. I guess the red line means you are bone dry?

 

You should try searching as there are many posts about this already. You'll find even more information on the topic than your asking. But in short there is no problem. That's the way Acura designed it.

 

This info is excerpted from a very long thread I started about fuel tank capacities, etc. and is based on actual and precise testing

a. When the low fuel warning light comes on, if you are getting 25 mpg you can go 94 miles, but if you are only getting 20 mpg, you can only go 74 miles. Of course, other miles per gallon figures will result in different results. This means you have approximately 3.7 gallons remaining.

b. When “miles to empty” (2004TL) or “range” (2005TL) reads zero, that is time to fill up, but you can still go 57 miles at 25mpg, but only 45 miles at 20mpg. This means you have approximately 2.3 gallons remaining.

c. When filling the tank, if you stop at the first shutoff, you will have about 17 gallons in the tank.

d. The tank will actually hold about 19 gallons, but it is not recommended to fill the tank to capacity, so stop at the first shutoff.
