Hopefully your dealer knows how to change oil but no guarantees.I went in to the dealer's shop with my first free oil change and was satisfied with the tech. I still take my Vette there but supply my own Mobil 1 oil. They supply the filter, check levels, tire pressure, multi-point inspection and top up windshield washer... Total cost less than $35.00...As long as I'm happy with their service, no way I will do it myself at that price. JMO
