You must use any required fluids recommended in your warranty or equivalent. Emphasis on equivalent.
You do not however have to by law have your vehicle maintained by the dealership.

Only way to void engine warranty is if you use an oil that is not equivalent to manufacturers specs.
If your vehicle is a 2011 or newer, your vehicle requires Dexos2 synthetic blend oil.
It's in the owners manual that's in your glove box.
