Grease Monkey, located in a handful of places around Seattle, is a great place to have an oil change-or any other fairly simple auto maintenance. Customer service here is very good. The professionals at Grease Monkey have, as yet, not lied to me about the state of my car. Also, if I don't have their current coupon they will give me the discount anyway. Grease Monkey does oil changes, transmission fluid, trans axle fluid, and numerous other maintenance jobs for your car. I have compared prices in the area and have found Grease Monkey's prices to be the same or lower than other comparable businesses in the area.
