I filled up in Hopkinsville, Kentucky and jumped on Pennyrlle Parkway and I did NOT use my cruise control ( I find the cruise control makes the engine downshift more than by driving with your foot. When going up a hill, I can gently ease off the gas pedal to where it will stay in overdrive and not downshift)

Anyways, I kept it at 55mph and those of you who has a 08 with the new 6 speed tranny will know at 55mph the engine is at a VERY relaxed rpm range.

Anyways.......I went to Evansville, Indiana. Then I returned back to the same gas station in Hokpinsville, Kentucky ( I went back down Pennyrlle Parkway again and kept it at 55mph with the pedal and not the cruise control)

Its good.........but not great, and I tell you the # 1 KEY REASON why it wont get better. Thats because the goverment has mandated all this stupid ethonal in gas (which makes it burn faster) so I dont care what kinda car you have, its gonna get less mpg due to the ethonal. The goverment added that in the fuel to help there own self, stop a think.......the more gallons we use, the more they make because they get taxes on every gallon of gas we purchase.

I can remember when the 2007 Escaldes came out with the 6.2 Liter. Gas did not have 10% ethanol in it, and I used The Escalde as a demo and by driving it like a egg was under the pedal, I got 24 miles per gallon with it.
