Well, at around 4,600 miles a big rectangular sign lit up on my display and told me something about an oil change/service needed soon. In five days I'll be going to a "New Toyota Owner" appreciation event at the dealership so I guess I'll get there a little early and have the oil changed and tires rotated too. I have a free oil change coming from the dealership and they toss in a coupon for a free oil change for attendees of the event. This dealership sounds like they have a good service department (award winning, etc.) so I doubt there will be any issues regarding the oil type or overfilling, but should I check the oil level after they're done? (I'll DEFINITELY wash it before I take it in and make sure to tell them to NOT wash it for me.) I'm REALLY hoping I score some swag at the event like a Toyota baseball cap or something! Hey, anyone ever seen a Prius baseball cap?
