This morning with 302 miles on the odo i filled up with fuel, took a bit over 26 gallons
dte read 672 when i restarted
drove 36 miles to home at 65 to 70 and it now reads 552 to emtpy with a 100% fuel load
that's a freaking huge drop in dte of 120 miles
dpf was at 50 and now 45 as i pulled into the communtity
i know only 300 miles on the odo, i should not pay attention yet
but seeing the dte drop like a rock on the fuel gauge gave me some concern
no fuel on ground or smells
Yeah. Completely Normal.
For instance when I filled up a couple weeks ago, I had been doing errands around town for the week before the fill up and all the way full it said just under 500 miles.
Went on a 120 mile round trip cruising about 50-60 (low rpm and steady) after the trip the fuel gauge was just barley under full and read 498 miles to empty.
DTE is based on the previous tanks MPG, but accuracy doesn't come into play until at least 3-4 tanks are through it. The key to getting them right is to always follow a set rule when topping off the tank. After the first click off, wait 30 seconds for the fluid to settle, then turn it back on at the same setting until it clicks off. Thats it, do no more unless for some reason it clicked off early the first time and you added a few more gallons, then wait another 30 seconds and top it off. Usually it will add about a half gallon and be consistent on every fill.
DTE is a factor of fuel level, distance driven, MPG at fill and continuing MPG read. I have actually had DTE go up after a fill after doing some towing.

i usually let it click off , wait a period then slowly run it up till i see foam, stop, wait and repeat until foam is no longer and i can just see fuel
do the same in the motorhome and it holds a 100 gallons, but there must be 4 in the fuel hose down to the tank
it really threw me off loosing over 120 miles in a short 36 mile run home
especially when instant was higher than 18 almost the entire time
my 2021 6.7 was stuck at 18 plus ...and on highway it would eventually climb into the 22, 23 range which set me at over 700 miles dte
i could run my house to daphne al and not stop for fuel
i double checked at home, no fuel smells or evidence of leak so we shall let her run and break in of sorts

I stopped topping off like that when a rollover vent valve failed and spewed diesel all over the place. They sit in a cavity at the very top of the tank and supposed to have a small air bubble to allow air to enter the tank ans fuel is used and seal up when rolling over to prevent fuel from spilling. Topping off to the neck of the pump can also fill that cavity and cause fuel to come out the vent.
Those brass looking things are the vents.

epa allows open air venting
I had no idea.
Thought it vented via some port in the system
thanks

Diesel doesnt vaporize like gas does. Gas turns to an explosive vapor, hence the use of the vapor recovery system, it prevents the cars from going BOOM on a hot day, but diesel doesn't form explosive vapors nor puts any fumes in the air, so it is allowed to vent to atmosphere.
