Having worked for several dealerships and running a brake specialist shop. I can tell you that $115 for labor is about the average depending on where you're at. Remember that the mechanic, that parts guy, the service writer, the parts manager, and the service manager (& assistant if they have one) all make a commission off of that $200+ bill. Most techs get paid an hourly rate of "book time" if they do it faster they make more money. If they do it slower, they lose money. Not to mention they own their soul to the SnapOn or Mac tools guy. The parts department marks up parts by up to 300%. But some things are reasonably priced if they have a lot of competition in the area. That said, yes you can do it yourself with redline, amsoil, or royal purple and saved at least half. But what is your time worth. Jacking it up, crawling back out to the tool box at least twice, getting diff oil all over your hands (and that smell if horrible and takes forever to fade lol), cleaning the surfaces before you put sealer on em, and cleaning everything including the drops of oil on the driveway. If the dealer does it and it leaks again, they fix it for free. If you do it no such luck. I personally do most of my own stuff, but I don't change fluids on my truck or car. It's too easy and cheap to have someone else do it. Just my $.02
