Ecoboost 3.5 Towing MPG Sucks

This is an incomplete equation, so bear with me. Assuming $2.75/gallon for diesel and $2.19/gallon for regular gas (current local prices at Costco), and assuming a diesel would get 15mpg towing and the 3.5L Egoboost would get 10 mpg towing, the price per mile for fuel would be $.183/mile and $.219, respectively. That’s a difference of 3.6 cents per mile. On a 500 mile towing trip, the difference is $17.50 (cheaper for the diesel). In my humble opinion, it’s not worth the difference. I hate smelling like diesel after fueling the work rig, and the exhaust stinks. Add in the annoyance of DEF and a tougher ride when not towing, and better mpg’s for the gasser when not towing, I’m happy with the gasser.
