bagel -> RE: Toluene as an octane booster...? (2/21/2008 2:17:15 PM)

93 octane is on the east coast because of the elevation level. In michigan they have 87, 89, 93...I'm pretty sure all gas stations on the east coast do. I was petrified at the fact that Utah uses an 85 octane as their base unleaded. I use 91 in my Jetta as much as I can
