You're right... I just did another half-tank mileage check, and my mpg actually dropped. This was with cold weather, and my tires were down at 30 psi.
Same driving style as before, but as I don't have a ScanGauge, I haven't been really "watching" my mpg. We'll see how the 40 psi tire pressure affects my mileage when I use another half-tank.
