As a 2018 Hyundai Kona AWD 1.6T owner who had ONE LSPI event on the factory fill and 87 octane, now I run 91/93 most of the time with some 89 here and there. You may want to get an oil that has 1,200 PPM of calcium or less. Some of these 5w-40's can have 2700 to 3000+ Ca. I think your car gets full boost 17psi at 1,400 rpm like mine does. You may want to keep your oil change in the 3,500 range since I found I had some soot. I have gone through different oils, but I think I will be now running 3 liters of Delo XSP 5w-40 and 1 qt of Redline Euro 5w-30. To get some more zinc and ester. I dump at 3,500, I am on boost more then most. In the upper midwest winters and my short tripping (-10 to 0 F) I get fuel dilution over 5% ( Polaris Labs) so I dump at 3,000 In the winters, I will be running Delo XSP 5w-30 and a qt of Redline Euro 5w-30 in the winters. I will be doing a UOA on the next oil change since I still have residue from the Amsoil SS 0w-40 that I wanted flushed out before doing a UOA.
