I doubt the diesels are going to burn half the fuel of the gas engines

difference in the cost of gasoline vs. diesel. There used to be, though.

Half as much, maybe less. Don't forget that the diesels have a lot
more low end torque and run at lower RPMs. The numbers that I quoted
are actuals from a guy who made the switch from gas to diesel on a
Bertram 33. He was getting more speed at half the fuel.
