Paul and Mike,

I routinely get between 28 and 32 measured MPG dependant upon conditions,
town/highway, AC on/off, light foot,thin wallet, working on bottom quarter
of tank (full tank weighs 145lbs).  Big mileage boosters are alignment, near
zero toe and camber, and tire pressure, stock 215-60s at 40 psi cold.
