I always run mine down to single digits and then fill up. I have hit 0 a couple of times, but never ran over a couple of miles after that. I don't buy into the "It hurts the fuel pump" theory either. My truck has 156K on it and I've done that from day 1, just as I did with the Dodge (256K) before it, and numerous others before that. I've never had a fuel pump failure in my 57 years.

 

I have a 2000 buick that i use for in town (parkades and such) and the fuel gauge broke one spring. So my wife told me don't bother fixing its too expensive. So come winter I had her filling it up every other day as the trip meter doesn't take into account idling. She made it almost a month and then the new fuel pump wasn't too expensive.

 

How many times have you actually run out of fuel?

Not sure which engine you have, but if you happen to have a 2008-present diesel engine make sure your bank account is full before you try it out.

 

The truck said 0 miles but when I did fill it after driving about 5 more miles it only took 31.7 gallons of a 35 gallon tank.

 

5.4L and I've never run out.

 

My wife thinks E means "Enough".

Anyway I had a question for ya, I just got a 2015 F350 6.2 Lariat and was wondering why my LCD display does not show the gears. Is it different on all or do you have to select something?

 

I know that in the past, running out of gas was mainly bad because the pump was cooled by being immersed in the fuel. Is that still the main concern?

With all the other crap that can shut the truck off (DEF, etc) you'd think they would shut it off to protect things.

 

CAPTFX4, I hit the switch on the gear selector and it appeared. If I select up passed 6th gear it goes off the LED. Hope this helps.

 

To the Op,

It sounds like you aren't getting the full 35 gallons in the tank.

I am on my phone so I can see if you have a truck listed in your sig. If it is a diesel are you just waiting for the pump to click off and calling it full or do you wait for the foam to go down and dribble in a few extra/ another five gallons?

My 2000 with an unmodded vent in the tank will shut off when the tank gets around 31/32 gallons in it. It is rated at 38 and I can easily dribble in close to 40 total if I fell like standing there for a while.

 

5 Miles to Empty - 35.72 gallons to fill it, listed as a 37.5 gallon tank, so less than 2 gallons in reserve.

 

Boy have i heard that one!

 

Based on my google searches, I can see that diesel foams much more than gasoline, so I can understand the concern now.

However, I have been told not to top of the tank in general, for a variety of reasons. Does this not hold true for diesels? I can fill gas up to the neck of my 1974 nova, but it won't have anywhere to go, so the biggest risk is expansion. I thought on modern day vehicles you risk the fuel going into bad places if you fill it to the neck.
