'14 GT Fuel Gauge

Hey, I have a '14 GT and I believe my miles to empty readout is off. As you all know the gas light will come on and the miles to empty readout will stay illuminated until you refuel. The problem is I have never been able to fill more than 12.5 gallons into my mustang. Does anyone know if this is a common problem? The tanks on these cars hold 16 gallons. If it matters I have the standard 3.31 gears, a manual trans, and run 93 octane. Thanks.

depends on the time of day. lets say you go and fill up mid day suns out, you'll get more vapor fumes or something ( not too entirely sure honestly ) and it will take up space that the gas can't fill? not 100% on that. if the gas is not in the sun ( filling up at night ) I've gotten more gas in the tank at night than durin the day

My .02 cents...

The low level warning, where the low fuel warning comes on is 50 miles to empty. Ford does not set it up so you could run out of gas. You can be sure there is about an extra gallon that is not compensated for in the CPU for the low level. You say you fill no more than 12.5 gallons. That leaves you with 3.5 gallons in your tank when you fill up assuming you are getting an average of about 20 mpg. Let's do the math minus that extra gallon I mentioned. 20 x 2.5 = 50miles (low warning level). So the extra gallon I believe is still in the tank at the 50 miles to empty. Is the discrepancy and why you think your miles to empty is off.

Agreed, the low fuel level indicator comes on pretty early.

part of the reason is the split/straddle tank. You leave 1-2 gallons per side.

I have a 2013 and have 6500 miles on it - The low gas warning still goes off when I'm at only 12 gallons used. I bet when the gas light comes on, you can still pull 75+ miles before you're stuck on the side of the road.

I tested this on mine a few weeks back. I drove it until the indicator said 0 miles to empty (with a gas can in my trunk just in case). I managed another 15miles after it said empty before I had to pull off and put in a gallon. I drove right to a gas station and put 15.5 gallons in her.

'13 GT with .373, I average ~21mpg, always 93 octane.

Be glad it doesn't run out when it says 0mi til empty. When my 05 said that, you might make it another block before you were walking.

+1 here. At least on mine the gallons used seems pretty close - if it says 15.1 used, about 14.9 or 15 will fill it up. I pretty much ignore the light - they have it set very conservative.

They set it that way so that your fuel pump will still be submerged in gas. They leave 1-2 gallons uncompensated for so that the pump will not over heat and prematurely fail. The miles to e is a guesstimate by the comp anyways. Hope this helped

I call BS on the time of day you fill up because once you open up the fuel tank the pressure is equal

The time of day thing doesn't matter anymore... the tanks are all below ground and temperature doesn't play a factor... it used to when the gas pumps had the tanks above ground and visible
