Fuel warming for fuel economy 2

[Blob97]

The radiator that I am currently running is set up to also function as a tranny cooler. Because I have a manual tranny I have no need for this function. Would there be any fuel economy benefit to running the fuel through this core in the radiator?

The vehicle is a 1996 Dodge Neon
198K Miles

LordMalak - Actually diesels have a cylinder pressure of typically 600 psi just before combustion initiates

When I was in college, I had a '72 Chevy that had a 307" motor w/a two barrel carb. I made an aluminum block that went between the carb and intake manifold, and this block was drilled to circulate coolant in series w/the heater core. I also drilled a passage for gas to go through between the pump and carb. It gave me 2 mpg increase in the winter. I believe it effectively leaned the mixture a bit to do this. Nowadays, with O2 sensors keeping the mixture stoich, it would probably have no effect on mileage, but hurt summer drivability.

I think heated manifolds have been around for about 100 years. Exhaust heat is actually quicker for reducing enrichment required for cold starts in cold climate.

The impact of also warming fuel will be minimal as there is nearly 15 times as much air as there is fuel.
