This is no doubt the truth, and goes a long way toward confirming basic
engine theory, which in an over simplified view says that an engine is a
furnace and the more heat (energy) you can transfer to the crankshaft
the better. The kinda sad part of all this is that even with EFI/DI,
exotic coatings, coolant tricks, any practical fuel, and great pains
taken to minimize any other losses along the way, the majority of the
energy in the fuel still goes out the tailpipe, radiator, and where ever
else to heat the great outdoors.

the way to the next gas station ;)
