Hey all,
I have a 2024 F-250 with the 6.7L HO engine. On a road trip I just finished, the “low DEF” warning popped up saying I was under 500 miles til empty. So I grabbed a couple of 2.5 gallon Blue DEFs and tossed them in the tank when I was down to about 280 miles to go. However, it now says I have only 498 miles until empty… After adding 5 gallons!
Any idea why it’s not resetting? I know it’s a 7.4 gallon tank but the 5 gallons being added would mean I have roughly 2/3rds of a tank.
Any insights would be appreciated!
