Consider BSFC for a bit, that is HP/HR/Lb of fuel consumed. BY WEIGHT, diesel and gas are closely matched. Not by gallon though.

E-85, can match modern diesel BSFC in specially designed engines. In other words, overall thermal efficiency can be excellent surpassing 45%.

But, the bottom line is and has always remained the same. Gasoline is very hard to beat for overall use.
You make three statements that disprove your fourth. Explain a bit more.
