I have a supercharged LS1. I know I can run 100 octane un-leaded but i was wondering if I can run 110 leaded? Will the lead in the feul mess up my O2 sensors? I have no cats and the rear O2 sensors are deleted. Just wondering if anyone done it or what will happen... thanks alot!!

The lead will foul your sensors, but they don't just suddenly quit working. They start reading incorrect and drift farther from an accurate reading, as they accumulate lead.

there are a few companies that make o2 sensors for leaded fuel. i can't remember who off the top of my head, but i know there are a few.
