Anyway, I averaged 69.2MPH and if the indicator is right, got 29.1 MPG.

Now, for a car that isn't even broken in, traveling right at 70MPH, with the AC going, that's pretty darn good!

I bet with a little break in here, a change to synthetic there, and maybe an upgraded intake (Stillen I suppose) this thing could make 30MPG on the highway.

Not too shabby.
