    UOA 2011 WRX 3,813 Miles M1 EP SN/GF-5

    Hey guys I just thought that I share my 3rd UOA result. I think the new SN formula is holding up well. So far it looks good as wear has been reduced to almost average. Also please ignore the extra sodium as that is from me flushing the engine with Mobil Super 5000 5w-30 SN/GF-5 before this fill.

    The a concern I have is that the insolubles has increased a little bit. I'm still running on this oil and shooting for Subaru's 7500 mile OCI's. I'm hoping that the insolubles settle out at this level. Do you guys think I should be concerned by the viscosity? My wear number look good so I feel like it shouldn't be an issue. I'll sample again once I hit 7500 miles on this oil with both TBN and TAN.
