- pretty impressive MPG number, especially with 5 people and 750 lbs in the bed! Guessing you may have been close to your payload limit...
I don't drive mine long enough distances to notice the DEF level fluctuating -- it gets filled every oil change at 5K intervals regardless of level.
(our resident biofuel expert) or others can chime in on local vs highway driving DEF usage to answer you question...
Thanks for reporting in with your MPG and owner experience.
