Dealership oil change techs get paid 9 to 12 per hour to start out.

Or they are paid .3 @ 18-20 per hour to change your oil. Either way, he's making between 5 and 12 bucks before taxes to change your oil. The list of things required to check and service during an "oil change" has grown to a list of 40 items, but you expect a "technician" to look over all those items carefully in 12 minutes?

It's just not possible. If you want good service, stop using the quick lube at the stealership. Only go there for warranty service, and find a local Toyota focused garage to service your vehicle. You WILL pay more than the Quick Lube at the Stealership, but you won't get ripped off in the end.
