Your typical OCI, the % remaining according to the OLM when you usually change the oil, and the type of oil used would be very interesting. I'm no fan of the OLM, but threads like this are of interest to me.
Edit: I see you answered while I was posting. I'd get a UOA @ 6K miles and tweak the OCI accordingly. Or if I didn't want to pony up for a UOA I'd cut the OCI to 6K.
Is the way to go in my opinion.
And I would think Jetronic could very well be right about his thoughts on the circumstances.
