will low octane gas trigger a check engine light?

sometimes it will trigger the knock sensor, triggering the check engine light. use high octane only.

95% of time it won't trigger KS. ur car will just run like sh*t and killing your engine invisibly.

stop being cheap 2-3 bucks extra for full tank won't kill you, but it might kill your sensors and your motor. Check the CEL maybe your O2 sensors and KS sensor crapped on you already.

This could be the explanation for my cell magicly disapearing. I changed my knock sensor but still had o2 sensor codes, after putin 91+ gas for about 2 and now weeks my cell is gone. (havnet check for codes tho cause i dont want the light coming abck up.
