Outshiner owns several businesses in the East Lansing and Okemos area. In Okemos, on Jolly Road they own a Quick Lube store where you can get your oil changed or wash your car (self-serve car wash).
Outshiner Quick Lube is great because I have yet to see a line or had to wait to get serviced. What's more, if you have multiple cars and you bring them in for an oil change on the same day, you get 50% off the second car (equal or lessor value, of course).
When I lived in Okemos, we would do this every 3000 miles, and never had to wait once.
