Hi kontiki,

They have always done this. Gasoline in MN needs to be different
from that in AZ.
and WHY? This is NOT necessary, it is pure politics and costs us all
money and wasted time and overhead. Thank you again Mr. Negative.

It IS neccessary. Just to name an example, evaporation proporties need
to be adjusted to climatic conditions. Try and fill your car in AZ,
preferably at a high altitude location, then drive it to one of the
northern states without refueling (probably won't work with the mileage
you get on current US cars..:-)) and try to start it in the morning at
below freezing temperatures. You will be surprised.

regards,
Friedrich
