As I waited 50 minutes longer than the "claimed 10 minute" service, I saw them tinker with two other cars. They were both smoking from the exhaust like they were about to blow up. The "technicians" revved the engines like they were in a Nascar race. Needless to say, they kept smoking. I was worried. Sure enough, as they finished my car, IT started smoking from the exhaust and under the hood! I asked what happened, but their limited technical skills couldn't tell me anything beyond, "we may have overfilled it." I am disgusted with their service. Go somewhere else!
