I now have run a couple of trips and have achieved 60 MPGs. It is now easy to maintain over 60 MPGs for long distances and even hold it between 80 & 120.

I suspect the break in period had more to do than anything. Even with a regular engine, there is a break in period where the gas mileage is reduced for the first couple of tanks. I've heard the period can be as long as 500 miles.
What happened when you went back to the lower octane?
