RV Fuel Issues & Prices - Post 'Em Here!

So, if I understand you, diesel bought on a gallon basis still contains a lot more usable energy than gasoline bought on a gallon basis. A dollars worth of diesel will get you further down the road than a dollars worth of gas. (on average). On a gallon by gallon basis, diesel is still a better buy even at the higher price. I think you would also have to calculate in the higher initial cost of the engine and also higher maintenance costs. Then again, diesels have a longer life time and depreciate less. Not sure how to figure that. I think when many people were making their gas diesel purchase decisions they were based on the lower cost of diesel.
