Average DEF usage is around 900 miles/gallon
Average distance between regens is around 830 miles
Average hwy fuel economy is 19.5-20 mpg
Lifetime fuel economy is 18.4 (about 80% hwy and/or rural roads; towing probably <10% of the time)
Best fuel economy (whole tank) is 20.4 mpg
All fuel economy numbers are hand calculated
