Here's my latest report. Ran 7600 miles on M1 5w30, I have about 26k on the WRX now. I used a Proline (generic Purolator) oil filter, and an Amsoil air filter.
The numbers look great, I will probably be running my current fill of Amsoil ASL 5w30 to 10k miles.
My last analysis: Oil Analysis: 7,247mi on Mobil1 5w30 (WRX)
