Stay out of full boost. Drive car easy down to half tank and fill up with 93 or 91. You’ll be fine as long as you don’t hammer it. If you really feel concerned you can go to harbor freight and buy a cheap syphon. Might get 9-10 gallons out with it then fill upI did the same thing accidentally to my 2018 Giulia with E85, all I seen was octane I didn't see the other numbers and ran it through the system before realizing something was wrong after the engine service light came on although the car still runs does anybody have any suggestions?
