Is this the first "Oil Thread" of the MO v2.0 era?
One of my more anal-retentive buddies runs the Harley synthetic in all three "bags", engine, primary and transmission (I think) on his dresser. He buys it by the box online to save money. He has never had any oil-related problems. IIRC, he changes oil at 5K.
He runs synthetic in his Duramax's (C5500 Kodiak, 2500HD), which are both on an Oil Management (analysis) program. He changes oil once a blue moon on them. Which is good, since they take almost four gallons each.
