Diesels increase in fuel economy down to about -10C 15°f as compared to -40°f/c the common winter temps hear at the top of the contanintal divide (even ancient low compression monsters). When you heat the air you just reject more combustion energy to the cooling system instead of moving you down the road. at a rate fo 1% per 10°fabove 60°fYou also create more NOx above 2500°f cylinder temperature |
This is why I'm suggesting to alow fresh-40°f air mix with preheated air. Not to hot and not to cold.

What do you expect to happen to my FE win I droop 30°f below the thermostat closing temperature (165°f)3 times per 200mi round trip?
