2012 Subaru Legacy 2.5i Premium oil change interval

Hey VDCdriver- I’m pretty sure that this community page is so that people who have questions can ask and people who can assist, do. If you feel my questions are ridiculous, don’t waste your time answering. Maybe you can talk to the people in your life in that condescending tone, but don’t for a second think it’s okay in the general population.
Clearly the manual says something different than the dealer or I wouldn’t be asking, though I’m not sure why I feel I need to justify myself to you. Please do not respond to any future post I may have.
