but he sees HIGHER mpg the higher the temps. that kills the AC thing.

I am just curious why I see almost NO difference and he sees such a HUGE difference over the SAME temperature changes.

now granted maybe I will also see a change now that I have a tiny car but as noted I have driven this metro in 80' temps and in 20' temps with NO apparent change in mpg beyond noise.

whats different between us? I live in PA (outside philly) and my commute is between 19057 (home) and 08215 (work)

I will have to start logging the temps as I drive.

how do you factor in the temp changes over the period of a tank? ie I fill upo every 3 or 4 days usually (multiple cars) do I just average the temps over the 4 days?
