Yep. Last couple of times I checked my highway mileage it was right at 31 mpg's running 70-72 mph. Got a couple 200 mile round trips this weekend so I'll probably check it again.
Fwiw. My average mileage (checked every fill up) has been 26-27 since the car was new.

 

Has anyone read this thread?
It started out wondering what was normal and how the cooling system is supposed to work.
Somehow it turned into one of those crazy hyper-miling thing where they want to overheat the engine thinking that hotter temps give better MPG.

 

Cat Man- I don't really know which tune SSFan has, been too long. But I remember that.

Don- does seem this thread has broken loose from it's mooring.

 

But it's interesting reading.

 

Ok, time to gently close the cover on this, we can compare fuel mileage and temperatures for days!!
