What kind of gas

[soltwede@privateI.com (Night Shadow)]

Very observative Kareem

You will find, that lower rated octane gasolines are used at high
altitude.

For example, I live at 5000ft (Denver, CO), the highest rated gasoline
around here is 91.  Where, in CA at sea level 93 octane is everywhere.

Our lowest octane around here that I have seen (up in the mountains) was
83.
