I just penned a quick article to my web site on my observation from towing my travel trailer over 3000 miles with my new Ram 6.4L gasser. I monitored 13 tanks of fuel using various octanes and tran...

"So…..The Diesel returned roughly 20% better MPG……but diesel fuel costs roughly 20% more…..so cost wise, it’s a wash."
Is not correct. 20% of two different numbers are not the same.
You did say your diesel was always 12-13 mpg no matter what. So lets say 12.5 mpg which if you deduct 20% brings you to 10 mpg. You state that your average was 9.34 mpg on your trip which is 25% less than 12.5.
You didn't state how much regular fuel was but according to gasbuddy it is around $2.90 in that region. That makes diesel $.58 cents higher at 20% which comes to $3.48. I very seriously doubt that it was this much of a difference especially since gas buddy shows $3.20 for diesel, but we will run with it.
So using these numbers with your diesel being at 12.5 mpg and your 6.4L at 9.34 mpg and gas being $2.90 with diesel being $.58 cents higher (again, I doubt this) at $3.48, the diesel would still come out cheaper over the course of your 2,700 mile trip by over $85 which is about the cost of another full-up. If you use the $3.20 cost for diesel that gas buddy states, then it would be a $147 difference.
Since you went there, don’t forget the cost difference of the Diesel engine over the gasser!
