One last question.... since your 2009 is Flex fuel are you running regular unleaded or E85? If you are running E85 then that is where your mileage is going.... E85 nets less mileage than regular unleaded fuel.

Yes, that was 90% highway mileage. I do very little in the city. I use Premium Unleaded Fuel - NOT E85.

I guess one of the keys is slowing down, but that ain't gunna happen anytime soon.
