After watching scary news programs that showed CA lube shops charging for services not rendered, I have never trusted those cheap shops to perform any service but changing my oil. Even then, I verify that it was done correctly by observing that new fluid was put in, and that the proper level was maintained.

I don't even trust the shops on my nicer vehicles that don't already burn oil. So, I change the oil myself once per year, regardless if it needs it or not.

Grease monkeys don't get paid enough to care if the job was done right, or if the drain plug was torqued to the correct spec.
