A couple of years ago I could count out getting a dealer shop to change the oil in my Chevrolet truck. The mystery shopping company which handled those shops no longer has them, and I don't see that another company has picked them up. Does another company handle them now or has the program for shopping oil changes for Chevy dealers gone away? I have an inherent distrust for Jiffy Lube and don't care to take my truck there for an oil change no matter who is paying. Thanks!
