BMW M3 Forum (E90 E92) - View Single Post - M3 tuned to 92 oct but refilling with 91...good/bad/no worries?

Route 16 · 01-05-2018, 05:52 PM

I just drove 2200+ miles on 93 flash for 6 days, starting with 92 octane on 2 tanks, 4 tanks of 91, 2 tanks of 92. All in all, no problem whatsoever, didn't experience hiccups, SES light, delay in power. But I will be uploading a 92 flash.
