According to this logic you should not follow the iOLM with Mobil-1 EP without a UOA to establish oil life at different mileages.
OP VWB will serve your needs well.
But you know that M1 EP is guaranteed for 15,000 miles don't you? Conventional oil is not to be trusted on most oil life monitors if you ask me. Conventional oils are pretty shot by 7,500 miles in normal driving. Of course this depends on your conditions & engine but this is just from the general consensus of UOAs I have read. If I didn't care about my engines, I'd run an OLM oil change interval on one of them & get a UOA for you. No way I am going to blindly trust a conventional oil to 10,000 miles & I think most would agree. We all already know synthetics handle this easily so why would we do anything else?
