Re: excess DEF consumption
There is no way you burned through 2 gallons of DEF in less than 400 miles. My guess is that your jeep sat for awhile (before you bought it), and somehow the DEF crystalized enough to hold the reading at 100%. Then with movement, enough DEF sloshed around the tank to de-crystalize the DEF and now you have a true reading. Go to the dealer, and have them refill it for no charge - (if they say no, have them call the Jeep rep - he will authorize a free fill, and if they still refuse, refer them to the PDI sheet, and that they should have added at least 6 additional gallons on delivery). After this, my guess is that you will be on par for 8 gallons/10,000 miles.
