As promised that I'd share my UOA result. This oil lasted from way back last August (2011) to February (2012) so this has seen quite severe operation +110F desert temps to below 20F temps of winter. It has seen a good share of mountain driving time. I'd blame the oil consumption on mountain engine braking. 7500 mile OCI seems like it's easily attainable. You guys can see a good trend since I sampled midway through the OCI.
I used the OEM blue Subaru oil filter during this OCI.
