Seriously? Wow. Do you trust your CPA or Doctor? Good grief. It would take more effort to get somebody else's used oil out of a drain bucket to put in the sample bottle and anyone with half a brain could tell if the oil in the sample bottle was new or used. Why would that even be a consideration even for the biggest hack when they were already standing there draining the oil?
I said what I said based on what I've personally seen at dealer service departments and on what you read about them the vast majority of the time on here, especially about the newer GM stuff and all the shady tricks they're pulling. I summarized it by saying "I ask because I, personally, have no reason to trust any GM dealership sales or service departments". I was accusing no one. This was before the OP revealed that he has a good personal relationship with the dealer. Also, I never said anything about them using someone else's used oil.
