Sorry for the delay I've been at the lake all weekend, quite a thread for my question lol.
So I did take this to the dealer when the CEL was on, they had it for 3-4 days, couldn't figure out what was wrong with it. They kept saying bad fuel, too much alcohol. They changed the plugs, put 87 octane in and it shut off. After a few fill-ups with 93 octane it came on again, and the next fill I used 87 octane and it shut off.
The reason I'm putting 93 octane in - it's cheaper here than 87, and if my car performs the same or even has a hint of better performance I'm happy to use the cheaper. My wife has an infinti q50 3.0t - we fill it with the same fuel have for a couple years, no issues. My mother has a Kia Soul or whatever those hamster mobiles are, she fills with it too - no issues (she doesn't have the turbo though, I believe the 2.0).
Not sure what to do - I will try another station with higher octane fuel and see what happens
