And the magic number is..............

 

Sorry about that, I get an average of 8.2 pulling at 70. I pulled my Airstream over 7,000 miles from Idaho to Tallahassee then back through Arizona and Utah with a side trip to California. Still averaged 8.2-8.5 on most tanks. I kept a diary of all gas prices, station/gas and mileage from tank to tank. I am using the 5-Star with the 89 Tow, but on the long trip I had a Diablosport Predator on the 91 performance mode. I like the shifting/tow/haul on Mike's much better.
