Guys I know DYI oil changes are nice and all, but if the dealer actually goes through the multipoint inspection, I think that in itself is worth paying someone else to do it.
At least for me its not easy for me to jack up the car safely without spending a little bit of time since i am on a gravel road. due to the age our cars its a good idea for every 6 months or year someone to do a quick check under the car on the lift for leaks or play in suspension (especially ball joints) . call me crazy but letting someone figure out ways to charge you could be a good thing providing you are there for service already...
I ended up doing the oil change myself, but a few months ago asked the dealer across the street how much they would charge if I brought in my own oil and filter, they said 25. not really the end of the world i guess.
I say this in the ideal world. I had a dealer do my oil change a while ago, (since it was nearly the same cost if I did it myself) they ended up overfilling it a bit. So I guess for us anal people keep doing it yourself, but jack up your car and check for play with a crow bar if you do decide to do your own oil.
one last thing. I called up another local toyota, their synthetic oil change service special was not toyota fluid (nor mobil1), so if the oil change price is low, verify you are getting oem filter and fluid or just go to walmart buy your own fluid and call it a day. I don't think there is a wrong answer here.
edit: to answer OP. I bought 2 gal of mobil 1 EP for 12 dollars each after rebate, and box of 5 oem filters for 25.
so about 30 bucks.
