I’m reading about 5.3L octane, RVP, octane tables, etc. I’m wondering if anyone has enough experience, or read enough around here, to comment on whether me putting last tank of 93 octane in and going back to 87 could cause an issue. I wonder how long the octane tables take to reset. Also curious if this kind of minor hesitation is common with newer 5.3 and especially on winter gas. I think I’ll pull the battery ground off tonight and see if resetting the ECU helps. Sounds desperate right? lol
