The SSEi is fed a minimum of 93 octane, with the occasional 94 octane fill-up. The GTP gets 94 octane most of the time, 93 octane only on long trips when 94 is not available, and it gets between 100 and 104 at the track.

As for the other cars:

'48 GMC w/'70 350 SBC: 94 Octane ONLY
1990 Grand Prix Turbo: 92 Octane
1993 Oldsmobile 88: 87 Octane
1995 Chevrolet Beretta: 87 Octane

I'm only allowed 91 or 93 in the Aurora

I regularly run 93.

89. i get a little better milage

I run 91, 92, or 93 which ever happens to be at the station I pull into.
I tried the 89 once I had to fill back up like 2 days later and it was normal driving not long distance or heavy stop and go, I think I got some where right around 200mi on that tank.

I try to stick with the 91, which is the highest my favorite gas station has. Been tinking about popping in some octane booster to see if it does anything for me.

89 is the same price as 87 here in mankato, so that'* prob why seth does it, and Why buy 87 then!?!?! Anywho i fill up on 89 here all the time, maybe i'll do 91 if i see a good price, or i'm doing some STP. Otherwise if it'* high, and i'm in the cities, i'll just throw in 87, it'* not dirty, it just burns different thats it.

is fleetfarm gas good or is it ****...cuz fleet farm by my college has premium for like 1.62...but accross the street at amoco(sp) its like 170...is there a difference?

Cosidering Fleet Farm doesn't make the gas, it'* hard to say. The couple of times I've gotten gas at a Fleet Farm I didn't notice any problems.

I didn't notice a diff between it and regular gas. I only had $5 one time, and i needed some gas, and it was LOW in my nova, so i went there. It'* always cheaper, but i don't go there anyways....
