Challenger SRT 392
You can powerbrake a little, now not crazy, I'm talking 800-900 rpm and that won't hurt a thing, even moving it in the garage back and forth will help get it warmed up. Probably will take a good 20-25 minutes to get the oil up to temp, oil temp now, don't look at the coolant temp.So what's the secret to getting the oil up to temp without driving?? Heck, I can barely get it warmed up a lot of times when driving, without going up a somewhat steep and long grade.
Unless by "operating temperature" you mean the relatively meaningless coolant temp.
And run your a/c compressor every time you start it like Dodge says.
