Regardless, I did my first oil change at two days ago 1700 miles, using Amsoil OE 0W20 and a Subaru oil filter (the correct "160" P/N filter). I also installed a Fumoto valve.

Oh, and I love my new jack, which reaches the lift points deep under the car very nicely (and yes, I did use jack stands before sliding myself under the car):

I replaced the thin rubber pad in the jack's saddle with a hockey puck, which provides lots of cushioning.
