I am averaging 13.3 MPG, this a combined city & commuting to work (lots of stop & go in Austin, TX), my best was 16 MPG for easy freeway driving 65-75 MPH, my worse was 12.6 MPG, the current millage is 1,850, so it should get better after3,000-6,000 miles.
I drove it very easy during the 1st 1,000 miles, mostly under 2,500 RPMs, after 500 miles I started doing 3,500 RPM power shifts, after 800 miles I did some 4,500 RPM shifts, I have not been over 4,500 RPM yet !.
I think is going to be difficult to get the rated 15-19 MPG.

Hello members, my first tank averaged 10miles mainly city driving. Hoping this will get better. Power is unbelievable. Hard to resist not gasing it! 2001 SC 5.4L
