Why would you not consider allowing the local Hyundai dealer do it vs Walmart?
I never owned a Hyundai but I have owned many or most brands and have had NIGHTMARE quick lube experiences but except for a few isolated experiences my Ford, Honda, Subaru, Ram. Dodge, Volvo dealers are rock solid doing oil changes and most if not ALL are less expensive than Jiffy Lube!
Heck, My local Ford dealer offers me a coupon for 1/2 off to come to my house with Fords Mobil Service and a oil change, multi point inspection, tire rotation AND new wiper blades in my drive as I sit on the front porch and watch, all for under $100 with coupon.
