For 9 months out of the year my starting temp is 90 Deg F or 32 Deg C I usually don't need to worry about warm up or cruise temps. However come late Nov, Dec, Jan, & Early Feb it becomes a problem. It gets into the 50s, 40s, and way down into the 30s. I don't understand how anyone north of the Red River survive! It's too Damned cold up north. FYI the Red River is the border between Texas & Oklahoma, anything North of the Red River is way the devil up North.
