OK maybe I'm nuts... but it's an idea I've been tossing around... Is there anyone else out there running 100 octane unleaded in their street cars? I'm getting pretty frustrated w/ my turbo setup and I can't get the power I want out of it. I live about a mile away from a Unocal that has 100 octane (about $4.29/gal... same price normal premium unleaded is in Europe!)... I'm tempted!
