On a new GM car/truck do you have to have a GM Certified Tech change your oil/oil filter OR the engine warranty is voided??? My friend was just saying that they have to take their 2018 Buick SUV to the dealer to have the oil changed. I asked why. He said they said it has to be done by a GM "Certified" tech OR it voids the engine warranty.
I say BS. It's just a scam/out right lie to get you into the shop to up sell you something.
Right? Wrong?
