Pretty simple, did the flat foot crank to build oil pressure before starting it up. Plug did not seem to have a crush washer on it from factory, so I’ll have to keep an eye on it for leaks. Took pictures with the date and products just to verify in case of warranty work later. Took about 25 minutes total. Also, you can enter your maintenance into the my Subaru app, but the dealer doesn’t connect the dots automatically.
