I am in Sedona altitude about 4500 ft
and drive to Phx about sea level or 1000 feet

In following the speed limit both directions
on two trips I was amazed at how much gasoline
I had left after the second trip.

I drive at least once a month to PHX
and sometimes once a week.

This was the first time I bought
that gasoline and the first time I had
so much left over.

If others here are noticing a difference
in BRANDS then I'm going to start paying
much closer attention!
