You want the real answer? Here it is in short form.

California sold 92 octane for a long time, but used a blend of oxygenates in order to hit that octane while still meeting the state gov'ts ban on other, more toxic octane improving chemicals. Well, the formula for that blend was owned by one of the gas companies, and they wanted to get paid for it by all the other companies (all your gas comes through one pipe, which is why they all had it in the first place -- it's not until it gets on the trucks that it gets "tailored" to the brand).

Well, the other companies didn't want to pay. So, rather than back down, they didn't allow anyone to use the formula and the octane rating dropped to 91. I have even heard that some testing has show it's not even really 91. :-( Toluene is your friend...

 

arizona has one station that sales 101 for 6.23 gallon...

 

We have 101 at local pumps for $4.65. It makes the evo happy.

I have one gas station that's local ( in Pasadena CA that's 10 miles away at the most ) that sells 100 octane for $6.30 a gallon

 

We only get 91oct here in vegas. I drove across the states in my evo a few years back and I noticed that 93 fell to 91 somewhere in the middle.

 

I live in British Columbia and we have 94 octane at most stations.

 

dont forget about the 100 at some of the Rebel stations.
I too saw about half way across the country the 93 stopped, which in turn made me get worse gas milage!!

 

Oregon sucks with 92 that is oxagenated in the summer. Good luck finding race fuel..

 

Reno sucks. $3.33 for 91 oct. today

 

haha next they will be trying push the flex fuel 85 into the evo's

 

Clark is absolutely right on this 1 & for those in AZ the 101 octane gas at the pump IS ALSO oxygenated as well. my '03 ran alot richer than non-oxy blended Sunoco 104 unleaded.

from what i understand, ADOT believes that the southwest/west coast needs lower octane gas to help "performance cars" pass emissions which is retarded cuz cars that run higher octane gas perform better/run smoother hence passing emissions. they also figure it would cut down on speeders since 1 would have to fill up more at a higher per gallon price. CA alone has more Porsches than the rest of the country, so they're out to get anyone whose vehicle doesn't look like a baby shoe (SUV) or a sandal (TRUCK)!!!

& AZ drivers need 2 watch their backs cuz of all the CA residents they now have. in due time they will bring their laws over also. they already got Homeowner's Associations (invented by rich CA residents to keep low income housing away) & all the houses look alike...

 

yeah sounds like az will sux soon... already expensive out here houses are getting way to much ...

 

uhh, no. there are at least 3 high octane stations in the phx area & a few performance shops that carry the happy juice. Union gas on 56th & bell (101) $5.99, In the zone on 44th st & chandler (101) $5.99, & a 76 station @ Scottsdale Pavillions (110 leaded) $8.00, & a well known EVO shop in Mesa sells Sunoco GT Plus 104 unleaded for around $8.00. Dont forget the tracks (Firebird & Speedworld) sell race fuel as well...

 

Also if anyone want s to see what octane they are "REALLY" getting at the pump, call the 1-800# on the pump u r using 2 reach the dept of Weights & Measures...

uhhh, thnxs
