I make much more money myself too, and it is not for the dollar amount.... but I will never trust anyone to change the engine oil in my vehicles, especially toyota dealerships. It is matter of getting it done right or having to worry "was my oil change done correctly, hmmm, did they put the correct oil grade or amount, did they use the correct torque setting to tighten the oil drain plug????" nooo way, I also perform tire rotation and never had an issue for over 15 years now and everything gets done with the correct torque setting.

Last time I had my TCH in to toyota dealership to recode the valve transmitter code into the ECU it took them two times to get it right and the end result was a dent around 4 inches wide in the passenger door and told them what happpened and kept apologizing and promised me they will fix it and told them I will think about it and although I made an appt I cancelled it for obvious reason(s). My point is, if you know you can fix it yourself right and you are willing, then do it.
