The only eth free fuel (premium) I know of is nearby to me, but it's $1.30 more than regular. At first glance I thought it was only 30 cents more...

I might give it a try one day just for kicks. The Acura specifies something like 90 octane, which regular is 87, mid is 89, and premium is 92. I've been putting regular in because mid grade is a ripoff (cheaper to just buy regular and then premium and let it mix in the tank.
