No matter which type of Genesis model you drive, we suggest using premium fuel for your vehicle, especially if you drive a 2021 Genesis G70 Sedan. To get a better understanding of your Genesis G80 or G90 luxury car, it's important to read your owner's manual. You can also chat with the Genesis of Arlington team to discuss which type of fuel is best for your Genesis GV80. The certified Genesis technicians at our Genesis dealer near Boston, MA, will gladly explain why premium fuel is the most optimal option.
