octane levels
I was filling up the Dart at CostCo with 93 octane and had a conversation with the attendant about how much cheaper their 93 was compared to 94 at Sunoco. Everywhere in Michigan the gas has 10%ethanol. He mentioned that the ethanol increases the octane but they don't advertise it. So I looked this up on line and found out this to be true. So how much increase in octane is there I wonder. Jysnflem
