Gas Mileage
I have a Chevrolet 3500 6.0 gas to tow our fifth wheel. Has anyone tried using Premium gasoline to see if your gas mileage would change? Just curious. Thanks

Some of the higher octane fuel in my neck of the woods is fortified with ethanol to boost the octane. In the grand scheme of things it will probably reduce the mpg.
