For the Pennzoil Platinum users out there, just exactly what are we talking about with the various reports of the oil staying clean thru a normal length OCI?
Is this "clean" description used for hot oil on a dipstick, or is it also for warm drain oil in a clean drain pan?
I'm tempted to run an interval of PP in my GMC Sierra 5.3L, just to see this "oil abnomally" firsthand, if the reports are valid!
