In my 2012 Forester, (130K) I have found the PP to burn about 1qt(+/-) per 7500 OCI. I switched to Valvoline, went to about 1/2 qt (mostly +) burn, same OCI. Now on M1 EP 15K stuff, so far at 5K no loss. I know the Foz has had some issues with eating oil, but we shall see.
Just my own observations, hope it helps.
