Hello all. I got my 2017 CCSB on July 4th. (God Bless America) I have been looking into he best way to warm up this engine. I have been reading very different opinions on what is good or not. I just want to know which is worse for this stock engine. Let it idle till it reaches 140 coolant and 120 oil temps roughly or driving it cold? By cold I mean 100 degree range(no cold weather here). I live in an area with a lot of hills and don't have the option to baby it until it reaches operating temps. Any info would be much appreciated. Thank you in advance.
