Diesel Exhaust Fluid

[Turnem]

How many miles are those of you with 6.7's getting when DEF gauge reads full? Mine seems to jump all over. Initially 4000 miles and now 1900 when filled. Seems to drop 400-500 miles when only traveling 100 miles. Weird!

so when i first got it .. it said 6k miles and after 1k miles it said 6500 mile until empty when i towed a trailer ... truck and trailer and gear was 16k lbs and the def lasted 4k miles total and when i was in the mountain using the exhaust brake it last 500 miles for half a tank ....
i would watch the video from this post helps explain high usage of def

Ford Tech talk DPF Regeneration video

New to the 6.7L and I did not know much about regen and found this video on DPF regen and thought I would post up. I am thinking this info is still fairly accurate for the 2020’s. So much for swapping out exhaust tips. Maybe moderators can start a sticky post for forum members quick access to...

Mine all over the place. seems to burn more with heavy towing and long sustained hwy speeds.
On my trip I filled it up at the truck stops. Seems to be the best and cheapest way to go.

I let mine get down to 1/2-1/4 tank before refilling. I have almost 7,000 miles on mine and seems like this truck drinks this shit like i drink whiskey when visiting the in-laws. filled it up twice. Been drunk more at the in-laws truth be told....

I used to get about 7.5k on my 2015, with a 5 gal DEF tank. On this new truck I’m getting about 5k with the 7.5 gal tank. I don’t stress about the fluid level and just wait until the 500 mile til empty warning pops up, then I stop at one of the gas stations with a Diesel island and fill up at the pump. I’ve got a few to choose from so I’m never that far from available DEF.

I have put 2000 miles on since ford topped it off and I am about 75-80 Percent full. in 10500 miles I have used 2-2.5 tanks
