That is where you are wrong. The energy balance and the economy differences of the engines calculates out that diesel would need to be 75 cents per gallon MORE than gasoline in order for them to just be equal.
Yea, it blows that we are getting screwed on a cheaper fuel that is easier to refine... But when compared against the design flaws of a gas engine... We still win.
Gasser working hard but running hot? Just piss away more fuel (REALLY drops the mpg) to cool the cylinders. Diesel working hard and running hot? Inject LESS fuel to cool the cylinders and EGT... OR just increase the boost / airflow. Has the same effect, but you still get the same power (work) from the engine. With proper gearing, increasing the RPM by dropping one gear also can do the same thing, reducing the demand for fuel and increasing the airflow which cools the cylinders.
Enviro-Nazis say diesel is dirtier than gas, because you can "see" the exhaust. Of course, they ignore the human-breathing-scientists that have said that tiny particles (less than 2-3 micron) are what causes asthma and emphysema in people by getting deep into the lungs and past the body's natural ~5-micron filters. Diesel particulates are normally 10-15 microns... So it would be like trying to inhale a basketball. The same scientists talked about the length of "hang time" of the particles in the air, and that the smaller ones from gas engines (B/c they have such little mass) can stay airborne for DAYS if not longer. Diesel however, fall to ground in only minutes, because of their much larger and heavier size.
Any way you slice it... Diesel wins.
Don't forget to pile onto our Politicians of both Parties who slapped on a extra Tax on Diesel fuel years ago because we were getting out of paying the Road Tax do to better fuel economy. I got a one time tax break of some pittance that does not make up for the ~ $0.10 gal surcharge I pay. Some states have reduced/eliminated the discrepancy, but Blago Land has not. I am waiting for a tax on farts next because farts contain methane that could provide untaxed fuel that could be sucked into the engine.
Anybody think the Electric Cars will keep getting out of Paying the Road Tax? Not me.
I would love to see a Prius get a ticket for not paying road tax by having a Solar Panel on the roof, Oh wait, Gov Quinn is working on that right now.

They need the money.
