Tank size

I ran my truck for about 12 miles after the miles to empty reached 0. Anybody know how many gallons of diesel it would take to fill the tank? I have a meter on my diesel storage tank that told me it took 31.92 gallons before the automatic nozzle clicked off but I’d like to know whether it is calibrated closely or not. Year make and model is ‘2021 F350 160 inch wheel base diesel. Specs say tank is 34 gallons but is that from run out and engine stalls to full to overflowing?

Edit: I topped the fuel off the next morning without driving the truck. So total fuel measured using the meter on my transfer pump was 33 US gallons. If I burned 1/2 gallon from the time 0 miles to empty came up until I filled the tank, I would have had 1.5 gallons in the tank when the DTE first showed 0 miles to empty. This seems reasonable .... is it? The reason I'm asking is that I calibrated my transfer pump meter using a 20 litre jerry can so I don't have a high level of confidence in its accuracy.

Ford says the “advertised capacity” is the difference between a full tank and running out of fuel.

Our truck also has a 34 gallon tank, and I have the DTE calculation set to “Towing”, which is a shorter history interval. When DTE reaches zero, I can pump 30 - 31 gallons in to fill it.

HTH,
Jim / crewzer

Thanks. Is that till the nozzle clicks off the first time or can a person squeeze another couple gallons in if you wait for the foam to settle?

Maybe the extra capacity is to keep a reserve so that the fuel pump doesn't suck air and implode itself due to lack of lubrication?

Ford says to stop fueling after the nozzle automatically shuts off the second time. I assume this is Ford’s definition of “full”.

Ford says the stated capacity includes an unspecified reserve.

I filled mine up to the tip top edge, sloooowly, to see how close I could get to the 700 DTE I got when it was new. Best I can get now is about 600. I guess after engine break-in, they don't get that good a mileage anymore? Because I can't reproduce it.

The “normal” DTE calculation is based on a relatively long operating history. If you averaged 20 mpg on the previous tank, then the DTE after a fill-up may well indicate 600 miles.

The “towing” DTE calculation is based on a relatively short history. I use this one exclusively because it appears to update regularly while driving. DTE is only mildly important to me when I fill up. However, DTE is quite important when I’m down to my last quarter tank, especially when I’m carrying our truck camper.

Cool, I never knew, but that makes sense. To use towing DTE, to you just put it in tow/haul mode to check it?

IMO, I would not run a diesel truck that low on fuel. High pressure pump needs fuel for lubrication and considering the poor design of the CP4 pumps to begin with I wouldn't take a chance of fuel / lubrication starvation by running the tank low. I've got a 48 gallon tank so I don't need to use all 47 gallons before I need to refill.

On your Platinum, the DTE selection is made in the Information Display “Settings” menu.
