Since nobody has answered your question, i'll try to help. Since I dont own an Accord, I'm not sure whats included in the 57K mile service, but I wouldnt lose any sleep over it. You have to understand that service intervals are pretty rough estimates, and dont let dealer mechanics fool you, when they try to assure you that maintaining your car to the absolute timetable is a do or die situation.

Your car will not blow up or anything. But I do appreciate your concern considering that many people buy a car and dont even change the oil for like 3 years. yeah, it does happen.

I would recommend that you do some research and find out what is included in these service intevals and just try to follow them yourself 'do without' the dealership. I can bet that $450 you're about to pay at the dealer might cost less than $150 at a privately owned shop. Dealerships literaly butt-rape many customers who dont have much knowledge about cars.
