I have a 2021 gv80 2.5 turbo prestige. It has about 14,000 miles. I used regular gas until December. Around Thanksgiving 2022 I got a message that there was an engine misfire. I took to the dealership and they reviewed the engine and said things were fine. Three week later the engine misfired again. Went back to dealer and they changed the coil on the misfiring cylinder to another cylinder and asked about the gas I was using. Since that incident happened in December I have used only premium gas and have not had a problem. Just wanted to let you know my experience. Absolutely love the car.
