what gas to use?
http://www.toptiergas.com/retailers.html
93 octane is abudant almost in every state except California
. Most gas stations around here offer up to 91 except for very few that offer 100 octane, so I end up mixing 4 gallons of 100 with 91 to get around 93 octane.

P.s. Don't even think about using regular on a car that requires min 91.
I filled my tank with Chevron 94 last night for 1.50/lit. It'll only cost you 4 or 5 bucks more than 91 octane not even per tank full.

2nd day, and i already had to add 56 dollars worth of gas (filled up at half way). chevron 94 at 158 today..
but good news is..
the engine sound will magically put a grin on your face afterwards
Latest Shell Tanker strike today caused prices to go to £1.99ppl/$3.94ppl
Pure Greed by forecourt owners!
was all about?

Excerpt from Porcshe Club of America (PCA)
"The rule of thumb for octane sensitivity in relation to altitude is as follows:
"The octane requirement (octane appetite) of an engine is reduced by one octane number for every 1000 feet increase in altitude.
"So, going from a sea level location to Denver [or in your case, Albuquerque] will reduce the engine octane requirement by approximately five numbers. This is for normally aspirated engines only. Turbo engines can be different depending on whether there is boost control.
"The octane versus elevation information is from Tim Wusz, Tosco/Union 76."
However, you also have a warm climate, which will cause the engine computer to back off the power. It will retard the ignition timing when the intake air temperature is very warm. This is for engine safety, and it also reduces power. Unfortunately this process begins at 25 C / 77 F, and the timing is reduced further depending on how hot the intake air becomes. This is because warmer air will increase the tendency to knock, and therefore, the octane requirement.
