Hey, this seems like a good thread to bring this up. This weekend at the DRagon I filled up twice at Deals Gap (93 octane was something like $4.35 a gallon).

Anyway, his 87 octane was 'up to 10%' ethanol. But his 93 was 'up to 3.5%' ethanol.

Is this normal? Is all 93 that low in ethanol? I am thinking so, might be why pumps say "up to 10%"???

Just wondering.
