Gas tank warning
 
Hello all. How many gallons is left in an e450 ford tank when the low gasoline warning light comes on.

Enough to get to gass station hopefully lol

Fill up as soon as the light comes on, then subtract the amount dispensed from your tank capacity.

I would like to know also, but just to know. I start looking for a station at 1/2 tank, it has taken me to about 1/4 to find one before. No way am I waiting for the warning light to come on. :)

It appears to be around 5 gallons.

"GasBuddy" is a good app for locating gas close to you. They give prices, and will go to Google maps to get you there.

I always carry a full extra 5gal gas can but will start looking for a station around 1/2 a tank. I only carry the gas can because I have come across quite a few stations I couldn't get into because of high drive entry areas. I would bottom out getting in or they have low overhangs.

If I recall, when I filled up in early July I am pretty sure the low fuel light had come on. It took 47 gallons which theoretically would mean that 8 gallons were left.

Every vehicle is different.
The average is about 5 gallons.

The fuel gauge is a much better indicator of when to be filling up.
If your low fuel warning light comes on, you are waiting too long.

There's a low gas light? I wasn't aware of that there was one on my 2017 E450 chassis.

Gumpster808 09-03-2017 09:05 AM

Good to know there is one but at 7.9 mpg last time I checked I better not wait for it to come on. X whatever in starting to look around 1/2 tank

Just a note to those who may not know.....your fuel pump resides in the bottom of the fuel tank. It uses the fuel sloshing around to keep it cool. Running your tank low allows the pump to get hotter, thus shortening the life of the pump. You should always try to keep 1/4 or more in the tank whenever possible. To replace the pump, tank has to be drained to drop it out of the vehicle.

Also, in humid areas, you could get water condensation in the tank. It adds up.
As usual, your results may vary!

Had a fellow Class C owner on Ford chassis tell me the same as he had to replace his fuel pump twice a number of years apart. Long tow from high in the sierras the first time. Second time, he was banging away underneath in the center of the fuel tank while his wife tried to start it. It worked! Then it drove it to the dealer for the fix. They enlightened him on keeping fuel level up as the gas cools the pump.

Reserve tank capacity around 7 Gal / 28 litre
 
I discovered the fuel warning light on our E450 for the first time last week. We were on the home stretch, and the first time I've run below 1/4 tank. So, to provide metrics to your question:

Apologies for using litres and US gallons interchangeably. I work and live in metric country, so ...

I get 24 - 26 litre/100km (9.0 - 9.8 MPG) on our Forester 3051S (2015) using a light gas foot. The advertised E450 tank capacity is 55 USgal (208 litres).

Warning light came on at around 720 kms and I drove gingerly to the next discount fuel station 20 kms further along, refuelled at 740 kms. The refuel, with as much top-up as I could squeeze into the tank, took 184.3 litres (48.8 USgals). Allowing for the 20 kms between warning light onset and refuel, means the reserve in tank at warning onset, would be around 28 litres (7.4 US Gallon).

Unfortunately (or fortunately, reading about fuel pump overheating in the thread), I can only offer a sample of one, for the experience. I have never filled an empty tank so cannot vouch for the accuracy of the Ford E450 capacity of 55 USGal

I was driving to the gas station on the way to the storage lot tonight and the light popped on. I drove about 8ish miles to the local Kroger gas station & put 46.627 gallons in so that left 3.373 gallons in the tank. This would mean the light went on with about 5 gallons left on my 2017 E-450-based Forester 3011.

For you southerners - if you do this during winter up north, you risk a fuel line freeze up... :eek: :crying:

Was wondering the same thing yesterday when my low fuel light came on. I had run the generator a couple of hot nights so I could have the A/C on and it got below 1/4 tank. I drove 9 miles and put 49.4 gallons in my supposedly 55 gallon tank, so 5.6 gallons left after nine miles at 65mph highway. I stopped filling the tank when it automatically shut off.

Gas tank warning
 
You guys like to live dangerously. I cannot remember the last time I saw that on any vehicle. I always fill at 1/2. What if the light comes on and you are stuck in traffic for the next hour?
