Hi,

If you don't have your owners manuals, you should be able to find some
info at www.subaru.com as well as Haynes, Chilton's or other manuals.
Don't remember how it was set up last time I visited, but on the Subie
site you're looking for a section on owners/maintenance or something
similar where you plug in your specific car's info. With the miles on
the '96 you may want to lean toward the heavier end of the viscosity
chart if it's using oil, running lower than normal oil pressure or you
live in a hot climate.

I'm sure this will rattle someone's cage and make me wish I'd donned the
flame suit before typing it, but all you REALLY need to be concerned
with is service grade and viscosity. Brand is a matter of preference I
won't even bother to address (we all have our favorites for whatever
reasons), and you can view the dino/synthetic wars on any car forum on
the Net!
