Another thing to consider is a light motor oil, perhaps a 5W20. Because it's less viscous, it reduces internal engine frictional losses from the cold start and luke-warm running. I concur with the block heater idea. Put it on a timer to come on one to two hours before your commute (depending on how fast it can warm the engine) so you won't waste grid juice keeping it hot all night.

My ultimate goal is not necessarily the highest mpg but to make my trucks more efficient configured as I need them.
