33G Gas Tank - Range Issue?

[Derek916]

Hi all, I have the 33G gas tank and on my first day of driving the truck I noticed my truck said I had 90 miles left of range. So I assume this means I had about 5-6 gallons of gas left(assuming 15mpg). I went to the gas station, and the tank only accepted 23 gallons, which is 5gallons short of what I was expecting. After this, my range updated to about 400 miles. Assuming I am getting 15MPG, shouldn't the range be around 500 with 33 gallons of gas? I've also noticed after driving 100 miles that my range is still about 370, so its not decreasing proportionally to the actual miles I am driving.

Welcome to modern day trip computer math. Even when your range shows 0 Mike's to empty, you will still have 2-3 gallons left in tank. This prevents idiots from running out of fuel. As for the range displayed after filling up, that number is based off the average fuel mileage over the previous 50 miles of driving.

Double check your range after filling depending on your dealership it could have spent along time idling, 9-10 mpg would not surprise me at all. Traffic and that fun right pedal also crush range

My dealer as told me its the same reader in the tank regardless of upgraded tank size... my truck with 33 gallon tank with low fuel light on never takes more than 26.5 gallons. So there is always 6-7 gallons in reserve.

 

[TNRamGuy]

Yeah I have the 26, normally have 5-6 left when I get the 'light ' depending on how much fun I have been having

I have a 26 gallon as well, if I fill up when the light turns on, I top off at about 19-20 gallons, so about 7-6 gallons, similar to RIRamGuy.

If I drive it to near zero, there is about 2 gallons left.

OMG! You guys have trucks that can handle 60 extra pounds of payload? I did not think this was possible. I would have sworn you needed a 3500 for that much weight. How do you manage?

But the injustice of a 33 gallon tank! It is SO MUCH PAYLOAD!

Take out the back seat, just make sure the dog called shotgun

Once the truck was broken in beyond 3K miles and acclimated to my driving, I have run the fuel level down low enough once or twice to have the “range” down to about 10 miles. Tank took just over 30 gallons to fill. My range goes up to ~570 miles with full tank. On long hwy trips cruising between 70-80 mph, it will certainly make or surpass that range. I have sometimes seen the sum of “miles driven” and “range” equal close to 590, however that is when I am intentionally trying to get max mileage by babying the throttle and leaving the MDS activated

If my trip involves going through Baton Rouge, LA… all bets are off

Bad juju starts to happen to modern diesels if you run the tank dry.

I have the 33 gallon tank as well. The one time I saw the low fuel light come on was literally as I pulled into the gas station on the roadtrip home from the dealership. It took about 29.5 gallons and I really squeezed that amount in there.

Guess by your screen name you could be sensitive to "go juice" loss

It takes time for the computer to figure out the range..keep driving and you'll notice the range will slowly come up as your fuel mileage does.

Was 15 MPG the actual mpg indicated? Or are you just assuming a mileage? The range estimate adjusts to the current mpg, so if you were actually getting 10-11 MPG at the time the estimate would make sense

Just another reason to avoid the 33 gallon tank.

Still waiting for the first valid reason.

You're not going to hit 2k lbs payload with that attitude.
