lovin Cali's 91, :ack: darn green people...and it's still expensive compared to other states 93,94, it's all the other additives, we will soon switch to our summer blend of gas so prices will increase a few cents more. :thumbs:

All Sunoco station sin Maryland carry 93 octane

Is there no other in Olathe, I've been using this station for my car but a bit of a drive unless I'm eating at Jalapenos. Were can we get race gas/ is ther a stationin the KC metro that sells it?

Southern Illinois:
I-57 & IL Route 149 (West Frankfort) - BP,
IL Route 13 just east of Carbondale city limits - Shell
IL Route 13 east side of Carbondale - BP

DO NOT USE AVGAS IN A MODERN CAR. Using 100LL AVGAS in the fuel will kill the catalytic convertor and oxygen sensor(s) in newer vehicles.

Another thing to keep in mind about aviation fuel in an automotive engine is that it's very vapor resistant. That is because aircraft fly through not only temperature changes but also dramatically lower barametric pressure as altitude increases. Avgas does make it harder to tune the car for street driving on a cold morning.

BINGO, we have a winner.:thumbs:
Haven't read to the end of this thread to see if anyone else has picked up on this seemingly little known fact.:cheers:

Add Hi Octane Fuel Xpress in Fayetteville, Arkansas to the list. 94 and 104 ethanol free Sunoco unleaded.

It's all over the northeast.

I wish...:ack:

Up here in the higher elevations (Lubbock, Amarillo, and west) 90 octane is about all you'll find. As mentioned before, altitude has an effect on it..

The gas's octane is the same no matter what the altitude. Engines don't need as high an octane gas at the higher altitudes, so the gas stations purchase lower octane gas. The pipelines move gasoline of many different octane ratings.

Have updated the recent stations plus the fact that 91 octane at the higher elevation is the same as the 93 octane. thanks all:cheers:

Just wait until we are subjected to Obama Administration mandated 15% ethanol added gas.

Also there was a mention to 93 octane gas becoming a thing of the past - anyone heard of this?

How is CHANGE doing you now?

I've heard a rumor there's 93 octane at a station at Speedway Blvd. and Alvernon here in Tucson but for all practical purposes it's 91 octane only in Arizona. Thanks to the government Overlord's at the EPA our fuel is oxygenated or cut with 10% ethanol during the winter months. There are, however, a very few stations that sell 100+ octane racing fuel. The Love's off I-10 and Wild Horse Pass Road (near Firebird Raceway) comes to mind. My engine is setup to run on 91 octane so I wouldn't buy 93 even if it was widely available.

Sadly, as a byproduct of their onerous regulations the EPA has targeted our entire economy for death.

93 Octane
 

Kentucky - nearly everywhere I have been has 93 Octane

anybody find anything above 91 left in South Dakota... Rapid City in particular?

i just moved out here & am tuned for 93 on 11psi with a stock LS1. (by the way - there's only one 93 station in Abilene, TX: the Valero by the mall on Buffalo Gap Rd) no problems in TX but i don't want to chance the altitude thing up here

I wish 93 was common in Kansas City. Kinda miss living in NJ where it's at every gas station

An easy way to find gas prices in your travels, those of you with smartphones, you can get the "YP" app. (Yellow pages) It's free. It will show you any gas stations in the area along with the grades of gas and current prices. Good for restaurants in your area too.
