Through the SC development there's been a lot of discussion of the availability of high octane fuel. I thought it might be interesting to see who has what available. I did a quick google search and did not find anything comprehensive. I'd be willing to develop a compendium based on what you experience locally. I might even put it on Wikipedia [img]style_emoticons/<#EMO_DIR#>/smile.gif[/img].

Anyway, you can PM me or post here and I'll see what we get in about a week.

Recently drove through a number of states so I'll start with what I found. This was the maximum octane available at commercial fuel stations. I am obviously not including race fuel.

OH - 91
IN - 91
MO - 91
KS - 91
CO - 91
NM - 91
AZ - 91
CA - 91

Would also be instructive to include whether ethanol is being added to the mix. I did not pay any attention to that aspect on my trip so I don't know what ethanol content might be in the above states.

Please include your data from Canada, Netherlands, UK, SA, AU, and every other locality represented here. Be sure to include the rating method (US uses (RON+MON)/2).

SC 93 with up to 10% ethanol. You can also find some stations selling 89 without ethanol.

this will be the trend over the next few years - as production cars all move to 91 to qualify for import to the US, the need for 93 is diminishing - there is a phase out plan in place - it won't be too long before we see 91 as the maximum everywhere for standard pump gas, with anything higher than that being "race gas", like the 100 available at a number of stations here in california

Seems like around here if the high octane go aways the stills will be coming back so we can start running on corn liquor again. With all the "street legal" drag trucks and cars driving around here there a high demand for octane. There are no emissions or inspections in this state so if you want to run a full on race motor with a drag bars your free to. It's kind of fun to see some of the cars running around here and the ones that show up at car shows on the weekend.

highest octane (sans race fuel) available legally in the tri-state area (New York, New Jersey, Conn.) is 93. Not long ago, 94 Octane was available here.

PA is 93 I think - and that is only a couple of brands, Sunoco being one of them. Like Dino said- you used to be able to get 94 at Sunoco, but that is now gone I believe.

Philly area for the record.

this one is going to be hard on many of us - with the new overlapping federal laws, which will bring emissions requirements to areas that do not currently have them, the fuel will also become an issue - the new laws allow the federal government to test air quality in any area, and determine whether or not to implement the emissions testing - unfortunately, as more people move into any area, the air quality decreases, and the emissions laws get more strict

so, for those who are running cars with higher octane needs, this is a two fold problem - not only will the fuel be harder to get, but the testing will preclude many from running at all

i have been trying to find a state by state octane listing, but it seems that it is more regional than that, with some areas of some states still carrying higher octane fuel, but other areas of the same state not

Over here in the UK, 95 is the norm for standard unleaded, and 99 is what I feed my 968 when the pay cheque has just cleared! , its currently at £1.25 per litre ($1.82 per litre at today's exchange)

Euro Octane ratings (like MPG & HP ratings) are measured differently then in the U.S.

correct - 95 there is 90 here - 98 there is 93 here

Loves truckstop, off the I-10 towards Tucson exit #162, has 110 octane unleaded. 7.50/gallon last I went.

Shoot I was there last week "Loves truckstop, off the I-10 towards Tucson exit #162, has 110 octane unleaded. 7.50/gallon last I went."

Could have filled up the Van [img]style_emoticons/<#EMO_DIR#>/wink.gif[/img] Wouldn't have mattered much I suppose - the thing is govererned at 117 (ask me how I know).

higher octane won't help you unless the engine is tuned for it - ours maxes out at 93 - anything over that, on a factory chip, is a waste, and only seems to make it run hotter - there are a couple of chips that can take advantage of a bit more octane, because they have a lot of timing advance up top, but i wonder about what else would be going on if allowed to run up there with a lot of advance - i never saw any problems, but i don't know how safe it would be on a tired motor

Yeah I have a higher boost map in my 951. Put in 110, select 20 psi map on my ebc, and go!! I never use it. Put a half tank through once. plenty of power in the 91 map. Still havent even had it tuned it for power yet. Just safety.

93 still readily available here in cenral Texas. Wonder how long, though...

Here in BC there is 91 every where and 93/94 at every Chevron station.

93 in Georgia, but up to 10% ethanol. There are a few stations (Shell comes to mind, I think) that have 93 with no ethanol, but you have to look hard for them.

Here in South Africa, 91 and 95 in Johannesburg (5700ft above Sea Level) and I think 98 at the coasts. No Emmisions issues to contend with.

that's probably RON - it's very important when talking about octane to specify which measuring method is used, as the numbers are VERY different

RON.. yip.. we're more Eurocentric/UK oriented in our stuff
