Yeah I think you're right about the location of the thermostat. My brainwave was off a bit I guess:)

I'm not sure the thermostat is stuck open or not. It's pretty new FWIW (~2 years old) and OEM as I recall.

I'm trying to get some better gas mileage out of this old girl and I'm trying to hunt down everything I can that could be contributing to the problem.

I'm pretty sure I opted either for the 92C t-stat because I wanted a hot cabin (as explained earlier) or a 90C t-stat because it was OEM. I can't remember.

Either way I'm pretty convinced I should switch to the 87C t-stat, I'm just trying to figure out if my mileage is going to improve from this move or not.

FYI in-town mileage right now is about 14.5-16mpg. The car is an AWD but the prop shaft is removed (for summer - will soon be re-installed).
