This is a west coast in general problem from what I know... here in AZ I can only find 91 octane. Question time:
1) Anyone in the Phoenix area know where to find 93+ octance gas?
2) What would be alternative options? Could I buy race/plane fuel (don't know if they offer unleaded plane fuel, but I would imagine they do), which is 100 - 110 octane, and then add the proper volume to come up with standardized ~ 93 octane? This sounds like a pain in the butt...
3) Does octane boost work effectively, particularly in our CS? I've read in the past mixed opinions on the usage of octane booster.
The reason I ask, is I think the dealer had it filled with 93 octane. After a few tanks, it seems like the performance is a little lower. I would attribute this to the anti-knock reducing the timing/compression to account for the lower octane. I don't know how sensitivethe car in reality is to ~ 2 octane less. If it is, I then my thoughts are founded, if not, it could just be in my heador related to the outside temps and other variables.
I'm told there are a few sources for 93 here in So. Cal. but I've never seen one. If you think the dealer used 93, why don't you ask him where he got it?
Good idea, but they are also 20+ miles away and I am never up there. I would assume big dealers have their own supply of gas on premisetofill their cars, right?I don't think their supplier would drop me 50gal drums on the side of my house, lol. I'll drop them a line, but something tells me that a viable solution will be gleaned from someone on here.
I did do an extensive search for places to buy 93 in Phoenix and could not find any info.
azcay - all dealers that I know of don't keep a their own supply of gas - all that that I've seen take the cars down the street and put gas in them, you need a lot of permits to keep gas on the premises... get on the Union 76 Web site and see if any of the stations in your area sell racing gas at their stations - they have a list on their Web site. You might also go out to Phoenix int'l or Firehaek racetracks and see if they sell racing gas to the public... it's usually 96 or 100 octane unleaded, and betwen $5-7 a gallon, an expensive proposition fo everyday use.
Don't use octane boosters - you'll scew up the car...

This is a FAQ on rennlist for Rocket Fuel... Buy a jug of Toluene from Sherman Willians or your hardware store and from what everyone says you will not have to worry about timing retard
One last tidbit, if you want to blend 91 octane with 100 octane race fuel to get a little over 93 octane, you'll be adding ~11 gallons 91 and ~4 gallons 100.
I have never heard this before until stumbling upon in my search for octane info. From what I gather, it does not increase octane, but does increase engine performance and mileageand is one of the additives used in 'Fuel Enhances' Got Acetone? http://www.pureenergysystems.com/new...00069_Acetone/
Ok, to extreme joy, I found out there is a Mobil 1 not far from me that sell Trick 101 at the pump. If anyone else in AZ is interested, if you want a 94 octane blend, which is what I found some local NA p-cars prefer, not based on numbers 'magic octane numbers'but on real perforamance, here's the math.
Take the number of 91 oct gals, and multiply by 0.43.
I usually fill up around 1/4 left, so I would pump 10gals 91. and then 4.3 gals of Trick 101.
Sure, it probably will turn out to cost around $6 -7 more than filling straight 91, but 1 redbull vodka drink at the bar can cost that much, I don't drive the CS as a daily driver, so an extra $7/week is not even a talking point to ensure that anti-knock doesn't reduce my timing one degree when I want to play.
hehe, yea, I found those shortly after my last post. I'm just happy I can try some 101 blend. If it came down to it, I was going try Toluene since it seems be pretty accepted amongst people with track cars and high performance street cars.
Still, on a side note, anyone have any experience with Acetone? From all reading of done on it, it does not appear to snake oil and lots people stand by it, even those with high line cars.
I ran on 40% toluene for over a year with one of my previous turbo cars with no problems and you can buy it fairly easily from paint stores for around $4/gallon which at the time seemed crazy but with gas prices over $3 it starts to sound better.
You can buy 54gal drums of VP street blue 100 for around 4.50/gallon and illegally store it in your garage which my or may not be safe in arizona.

BTW across Wyoming the 'premium' gas was 89 octane, it was 85/87/89 ! Needless to say we moved on until we found higher octane, luckily we weren't near empty.
Really doesn't make much sense to buy a car if you can't fuel it correctly within your area[img]/fckeditor/editor/images/smiley/MWPX/confused_smile.gif[/img]

89 octane at that elevation (I assume you were around 5000 ft) will be the functional equivalent of 91 octane at sea level. As you know, gasoline sold in our area runs two octane points below what you get at sea level, yet it doesn't cause problems.
The exception is when you fill a jerry can with 85 octane fuel in Denver and dump it in your truck when you are at low elevation.
The 91 octane here behaves like 93 at your location. I'm surprised that you found some 89 out here being passed off as premium. Usually it is 85, 87, and 91 here, where at sea level I see 87, 89, and 91.
