DEF in a 2012 Ford 6.7l

[fireman1317]

So I have had my truck for just shy of 2 months and have put on just shy of 2,000 miles. I have filled the truck 3 and 1/2 times now and have the 37gal tank. Assuming the DEF tank was full when I bought it, should it not be getting close to needing to add DEF? I have not seen a dummy light come on yet. Just unsure.

I have a 2011 F250 longbed RWD diesel and I don't have to refill the DEF unless I tow a lot. I use 2 and one half gallons per 8,000 miles unless towing most of the time and then about 2 and 1/2 gallons per 4,000 miles.

The average interval on the newer trucks is about 5K miles per tank. You will get a warning when it is low. No big deal at all to top off.

Top off at the pump at a truck stop. It's a lot cheaper.
$15 for 2.5 gal at Autozone.
I filled up at Pilot 4.5 gals for 11.72.

[Skyliner]

I'm putting in 2.5 gallons every 2,500 to 3,000 miles.

I'm using nothing but the best, Supertech DEF for $7.88 for 2.5 gallons available from Walfart.

I push the "setup" button on the steering wheel and it goes thru it's paces.
Shows oil ok, etc, and shows DEF level ok. Wish it would show 1/4, 1/2, 3/4 level for the DEF. Guess it would give a message when you need to add DEF.
Haven't experienced it yet.

Wait until it says you have about 250 miles to empty. It doesn't like to be filled when it is not almost empty. I like to go to truck stops and use the DEF pump. That way, you can fill it without over filling.

Consumption depends on driving habits and towing..

I haven't had to fill my DEF tank yet. Just turned 91,000 miles on the clock. 😉

Only trhe Dodge has a nice DEF gauge.

I use my Edge CTS digital gauges and it shows me % on the DEF tank whoch is much better then the "ok" crap I get until it is at 20% or a miles countdown.

[I Simpson]

Ford's probably cheating. My TDI. Never needs DEF

[mike.t]

Ram comes with a DE gauge no more wondering for me

Our 2015 F350 has a warning come up on screen at 500 miles left on DEF. have gotten in habit of filling it about every 5 or 6 tanks when I pull into Pilot / Flying J if under toe, takes maybe a gallon. Just never really keep check on it one of those things you got do just like buying fuel.

Refilling the DEF tank will depend upon whether you have selected Normal or Towing. You will go through DEF quicker if you are towing your RV than if you are driving under "Normal" conditions. In the Ford F-350, you will get warnings starting at 500 miles to go. Once you get down to empty, the truck will go into what some refer to as the "limp" mode (< 55 MPH). I recently was faced with a failed DEF Sensor C. I decided to have the entire DEF system removed and done away with. No more messing with DEF, no more warnings, or other such problems. There is an expense involved with this type of modification, but no longer have to worry about filling or paying for it. A good Diesel shop can do the modification in a day.

Wonderful however most of us don't tow with a Yugo.

Great I am sure your grand children will thank you for the clean air you left for them and theirs!!

Towing will cause for the more consumption of the DEF fluid as the exhaust filter will need to be cleaned more for fuel requirements due to load. Also you can look at menu to see how much fluid you have. Don't run it out! Will cause loss of reduced power and then tennis shoe mode.
