Thanks everyone - the question was intended as more of a general/philosophical inquiry which is why I didn’t tell you the make, model etc that some of you requested.I guess I should have made that clearer - sorry.
I appreciate everyone’s comments - Caddyman, I didn’t know there was such a thing as “break-in oil!” I assure you I’ve read the owner’s manual cover to coverand will abide by it, although old habits do die hard as dagosa observed.
jayhawkroy - this is my third Subaru too - sold the old Outback wagon and bought a new Legacy sedan.
