Observations regarding ambient temperature and MPG.

I shared this on the FTE forum and thought it might be of interest to owners of trucks powered by relatively stock 4.9L/300s.

I've noticed the same thing in my daily drivers (4.0L EFI Jeeps).

Yes here in Nebraska, winter time... When it stays in the teens or colder. Everything I drive loses 2-4 mpg :? Been known to cheat abit. Run a tank type/ heater hose, Engine heater :thumbup: It does help, and its nice to have a warm cab sooner... No doubt the winter blend gasoline burns up faster too.

Nope those are getting rare around here in the rust belt.

Mos of the ones with the least rust I see are 2WD versions. Of course they a piece of cake to convert.
