@Terrificli -- that may be case at those "quick lube" shops, but the lube technicians at dealerships do tend to go into more depth when they have a car in for an oil change.
Regardless, even the "quick lube" techs can tell you if there is a major problem with your car, problems with tires and etc. They may not change tires and such, but they can alert a customer if there is a problem. That's a fairly routine part of the job, really. Quite often, the lube technician is on the front lines when it comes to maintaining your vehicle -- they may not work as mechanics, but they can tell you if you need to see one to avoid problems.
