Maintenance/oil change in Portland, OR?

Hi! I'm new the forums as you can see. I really wanted to ask where I should go for maintenance stuff in the Portland, OR area. I live and work in Portland proper so something in town would be preferable but if you have a strong recommendation in the 'burbs I'll take a look and see if they'll work with my schedule. I mainly need an oil change but the car recently hit 100K and I haven't been keeping as close of an eye on it as I should (yeah yeah I know, naughty) so I want to go somewhere good so that I know they'll catch anything important without making stuff up. Thanks for any ideas you guys have!
