Im getting my car tuned saturday. I have Simple Digital Sytems, so I can completely control the ignition timing and fuel curve. Is it safe to run 10lbs on 110 ocatane? This would be just for the track. Completely stock h22a1

 

this should be no problem what so ever with race fuel and proper tuning

 

It'll be fine

 

could hurt the o2 sensor but I doubt it, I think 112+ octane starts getting hairy for o2 sensors

 

Fuel octane does not affect O2 sensors.

O2 sensors do not like leaded fuel. 110 octane is not necessarily leaded.
