(weather permitting)

I drive 250 miles every Friday from Page, AZ to Show Low, AZ. It is supposed to be just over freezing when I pass through Flagstaff. I spend a surprising amount of that drive with my temperature gauge reading cold.

If I speed up, it will warm up, right? A warm engine gets better fuel economy than a cold engine, right?

I am not asking about speeding, sillies!

Ninety-one miles of my route is the I-40, with a 75 MPH speed limit.

I only drive 65. Some semis pass me, but others only drive around 55.

What do you guys think?

I wish my OBD-II reader were working within specified parameters. Input! Input!
