Dropped this OCI a bit because I have been driving ~1.5 miles between home and school since the last oil change. The engine almost never gets warm so I changed a bit early. I used Mobil Super 5000 5W30 SN again, and looks like things stayed very consistent. Good thing, because I think I bought over 100 quarts of the stuff from Autozone/O'Reilly for their $10 oil/filter deal. Returned the STP/Microgard filters for store credit and bought more oil. Anyone see anything wrong with extending back out to 8k+ (maybe 10k) with a quart make up and maybe a filter change in the middle? My powertrain warranty is up now.
