36 Gallon Fuel Tank

[fordtruckman2003]

I learned something new with this thread. So 0 miles is like 2-3gal left, meaning that 800+ miles of range us closer to around 900 in a 2.7. I've never let it get below even half a tank, but I haven't had the chance to road trip yet.

I dunno sometimes it races very quickly to 0 and makes me doubt how much fuel I have left. Never put more than 34 gallons in with a little drive past 0. It's cold out now so I can probably squeeze in 34 easier than my usual 32.

There's a youtube video of a guy that intentionally ran his F-150 out of gas he had a 5 gallon can with him. He made it 50 miles past 0 dte before the truck died!

I think I've gone 10 miles past 0 DTE to get to gas station I wanted. I remember thinking I'll be the one dumbass that actually runs out of gas doing that.

I thought the same thing the first time I went past 0 as well.

Ford has had the same tank forever.
Older generation had issues parked on hill low fuel couldn't pick it up.
Ford fix was software change leave larger reserve never be in situation where your truck can't pick up the fuel.

You can drive well past 0 miles to empty. Just don't park on any hills.

I routinely hit 0 and put in 32 gallons, many of us do. It's a well known feature on this generation.

Still better than the smaller tank offered even with the wasted space.

As Spock said “ or the 1”…that would be me! I’ve only ran 1 tank of gas to the little needle being below the E and that was to see just how far down it would go. And I was still scared to death I’d be on the side of the road. Mom always “threatened” but in a loving way about not running out of gas. So we always fill up at 1/4 tank.

I always fill mine when it gets close to 1/4 mark. It doesn’t matter to me what the mileage is. I bought the truck to drive it how I want. I am not going to drive 60mph on the interstate just to get over 20 mpg.
I had a ram diesel would get over 25 running 75 mph but then oil changes cost much more and diesel is higher. It’s all mindset. I have the 3.5 EB but next truck will have the 5.0.

Living out of town, I don't like letting the tank get below 1/2. Also, I hate having to get a loan to fill my tank from empty....lol.

Probably another thing to consider, the 36 gal may be a nominal number.
maybe some bigger, some smaller.
I think about this as my square body Chevys used the same tank on both sides.
16 gallon tanks in my short ones were lucky to hold 15 even af running dry.
my long bed with advertised 20 gallon tanks was also a bit off.
left side would hold 21.5 and right side 19.5 after running dry.
I would always empty one tank before switching, so at every fill up a different tank was dry, and over 30 years of this those numbers are still etched in my head.
Again, same tank on both sides.
Just Put a 24 gallon tank into my old ElCamino—23 gallons from dry to leaking from upper vent
20 gallon in my ranchero is only 19 from dry.
Doesnt really bother me as I fill all the single tank cars at about 1/4.

I have a neighborhood question for a 36 gallon tank, 2023 F150 XLT 5.0. Despite driving it down to low "miles left" (as in 38 today), I can only fill to a max of 30 gallons. 100% of the time. Never 31 gallons. No matter how hard I try. This includes the slowest tank hand feeding after it clicks off at 30 gallons. It eventually runs over despite how slow the fuel is delivered, but never exceeds the 30 gallon range.

When I get in to drive off it shows a new range of, for example, 621 miles today, which works out to 17.25 mpg when divided by 36 gallons. I average 18.2 on the dash.

So, by throwing dog vomit on the wall my 30 gallon fill seems to be in the neighborhood of 17.5 mpg using 36 gallon capacity. My average is 18.2 on the dash. So I think the 17.5 mpg is a reasonable number, after examining the dog vomit.

I have never encountered this on a vehicle. I have probably owned 20 or more in my 71 years. If it said a 22 gallon tank, that is what it held, etc.

To sum, 621 range miles divided by 36 gallon capacity averages 17.5 mpg. I am averaging 18.2 according to to the dash. But still cannot get more than 30 gallons in refill.

621 miles divided by 30 gallons is 20.7 mpg, which is nowhere near the real world 18.2.

So, what am I missing? I haven't asked the dealer since I doubt I would get a knowledgeable answer. I am not even sure how to frame the question yet.

So far I have never filled at the same gas station so there appears to be some consistency in the numbers. No one is charging me for 30 gallons but delivering 35 gallons.

Is this making sense to anyone? It's giving me a headache, as is having to read dog vomit on the wall.

Otherwise it does not appear to affect me much. Just bumfuzzled.

Just did a 5400 mile trip over Christmas, 30.6 fuel tank ('23 PB), usually never let it go below half since we were in the mountains plus cold weather. My lie-o-meter indicated 21.5 for the entire trip. Stayed within speed limits the entire trip. Afterward, I added all the fuel receipts and divided total miles by total gallons used and it was 22.5. Now I did round to the nearest tenth on gallons, not 100th's. Either way with that fudge factor, I would still be over 22 mpg. Now that's lower than advertised but we all know those advertised numbers are B-S, but overall, very happy and was totally comfortable in this land yacht the entire trip.

I saw it said here but never rely on Fords MPG in the dash it’s never correct usually optimistic 1-1.5 mpg
If I ever have concerns about when any new vehicle will run out of gas just bring some in can and find out
I bought new 79 Ford Granada on 1st trip with it I ran out in Ohio 3 miles from exit withfuel gauge @1/8 tank
Just one of the many defects of a USA made vehicle of this era

Forget the high tech baloney, reset trip 1 after a complete fill, on the next full fill divide the gallons purchased into the miles driven. Do this 5 times to get a honest average.

Now you have a honest hand calculated MPG.

Look at it this way if Ford calculated Empty to exact Empty there are enough yahoos today on the road trying to drive to the very last drop in the tank that the roads would be filled with these yahoos who thought they could go just a little further.

Or you can join the above crowd and wing it at empty to find the missing last 6 gallons by trying to drive 103.5 more miles.

I have been tracking fuel consumption since day 1....my truck is averaging 13.674 liters per 100 km.... or 20.66 mpg Cdn or 17.2 mpg US

 

[PowerBoostSoCal]

I regularly drive it to zero and beyond ... most ever put in was 34 gallons. At zero it is about 32 gallons.

 

[Vin]

Time to go from my OEM rake, to a squat : )

Haha. For sure.

Seriously though. My truck is leveled and I'll bet it helps me "get more" in the tank. Also:

Disclaimer - I'm a flatlander and I wouldn't screw around with driving miles past "empty" in the hills.

20.66 mpg Cdn

?

0.86 to 1 honest to God real gallon
