I'm sure everyone will appreciate your feedback, no worries about bumping this thread.
I will question when you made your last oil change. You state that the M1 0W-40 runs cooler than the last oil you ran, but I have a very hard time believing that the ambient temps are the same now as they were then. It's October now, so that would mena you changed the oil last in June or July. Not really an apples to apples comparisson in regards to oil temps since the average temp in July in Georgia is about 1 million and it's 75 in October.
