I'd like to know both the conventional wisdom about, and the common practices you guys use, starting your Explorer after it has been sitting outside all night in 40-60 degree temps.
Some of my friends start it and drive away immediately. Another buddy lets it idle for 5 full minutes before moving. I have tended to wait until I detected a slight uptick in the temp gauge needle, but sometimes I'm in a hurry and only wait 30-60 seconds.
Everything I've read on the topic is non-quantitative, meaning the wording is "briefly" or "for a little while" etc.
Thanks.
