Fuel gauge question

How accurate are the fuel gauges? Yesterday I was on empty, dash read out said I had 30 miles till empty but when I filled up I was only able to get 25 gallons in. I have the 35 gallon tank. thanks, Mike

Depends on how full you fill your tank. I use my dasdaq to read my fuel level percentage. And its actually pretty accurate after you get under the full line because if you fill your tank like I do which is topping it off it stays at 99.997 for awhile. As far as your miles to empty it all depends on what your lie-o-meter is saying so I wouldn't gauge my distance on that.

The fuel level percentage gauge work like the fuel indicator telling you how much is left? I'll have to try it. My trucks gauge has been way off sense new.

I always just take an average of my miles to the tank....mine being 29 gallons and topping it off to the neck I normally get 490-500 miles per tank...so I just set the trip every time a I fill up and gauge it that way

I don't let it get below 1/4 tank. I don't like walking.

I'm with Grease...walking sucks. I would trust the gauge over the dash display. I'm sure the display, not the Dashdaq, tries to calculate driving habits..heavy in the pedal.

I have been fighting with FORD about this issue since I bought my truck 2+ years ago. 30.5 gallon tank, gauge reads empty and display reads 0 miles to empty and the most I can get in the tank is 24-25 gallons. I have taken the truck in 3 times for this issue and everytime they tell me nothing is wrong, but can't explain why I can't get more fuel in it. The last time their reason was that the tank is so long that that with 3-4 gallons of fuel laying in the bottom of the tank it would be spread out and probably not registering on the gauges. I have given up, but may get a 5 gallon can of fuel and drive the truck til it starts acting like it is out of fuel just to see how much farther I can go past the 0 miles to empty message.

Same here. I took mine in once, and they said nothing is wrong with it. Pulled out a tech bulletin where Ford is saying that they put about a 5-gallon buffer in that reading. But, like you, I don't like walking, so I always fill it up after I get below 50 MTE.
