Valvoline synthetic will be fine as long as it's the proper weight. What I would be concerned about at a quick lube place is if they're going to under/over tighten the drain plug, or not even put it back in. It sounds rediculous, but it happens more often than you woul think. I remember a few people posting on here about how they left the oil change place and their engine locked up, only to find that they service guy never put the drain plug back in after draining the oil.
From what I can gather most dealerships will use whatever they have their hands on and is cheap.. they'll tell you it's whatever you ask for, but that doesn't mean that's what actually ends up in the car.
