Not sure where to post this, BUT where in the US is the highest octane pump gas available??????? I see 93 here in the Houston area...Anyone know of higher??? ....Just curious.Thanks, Tom

I've been to a lot of states and never seen over 93 (that I recall). Usually the higher the altitude the lower the octane ratings available (because you don't need them at higher altitudes).

A lot of places will sell 100 or 103 octane unleaded right at the pump.

Out here in SoCal its $6.50 a gallon... I usually blend 3 gallons of 100 octane with 2 gallons of 91 octane and make 96.4 octane.

when i lived in florida... i saw one station and i mean one station only sellin 103 oct.. i couldnt believe it... i know alot of you will think im lying and i cant blame you... and when i lived down there i didn see a couple stations selling 97

wow.. i shoulda read the guys post right before me sry bout that dude

We have a local station that sells 103 for 3.87 gal currently it's great stuff

Varies per area and goes off of 1) altitude 2) supply and demand, I cannot wait for E85 to be readily available at the pump, supposed to be equivalent to 105 octane, but you use more of it, I'm not building an economy car either.

I know of 1 station in these parts that sells higher octane fuel, I think it's 110, it's purple in color.
There is also a racing store that used to sell leaded race gas, not sure if they still do.

I've seen 103 and 110 in a few places around here.

There is a station 10 min from where i live that sells 100, they call it "racing fuel" its about 5.50 a gallon

my friend's dad built a stroker 383 for his 68 stingray to run on E85(we have it readily available in MN, about 1 in 3 gas stations here sells it) and he's making something like 430HP (cant remember exact numbers) at the rear wheels. he said he gets something like 12-16 mpg average, and on longer highway trips its closer to 20mpg

you can't put E85 in a standard engine can you? I think they have to be specifically built to run that.

my grandfather sells 100 octane low lead in miami. It was good enough for a lamborghini countach, its good enough for a firebird


btw this was in 98.. note the 2.04 for 100ll

I read sonewhere higher octane gas causes carbon buildup. I run midgrade.

Here in Ottawa Ontario Canada, the regular pumps have 87, then 89 then 91 octane, however Sunoco sells 94octane at the pump as well. Havent seen any higher sold to the general public at a pump.

What about the Houston, Texas area?????????????? Thanks, Tom

Tom, you're going to have to do your own homework here, buddy. Call up local gas stations, and ask them where to get 100 octane gas. Or visit the three websites I posted up in reply #3 and see what they have. Lastly, call up your local racetrack, Houston Raceway Park, and ask them where to get it. Here's their website to help you: http://www.houstonraceway.com/

with alcohol you have to nearly double your jet size (if using a carb-ed engine) you also have to change your fuel lines, and gaskets, alcohol likes to break up deposits and eat away at and rubber and plastics.

you probably could get your car running on E-85 with little or no modification...but i cant promise it would run very long.

also, although E-85 is a equivalent to higher octane gasoline, it has less stored energy than Gasoline. E85 is 81,000 BTU/gal where as Typical US-blend gasoline is around 112,000 BTU/gal. That gives E85 72.3% the energy content of gasoline.

Highest I've seen here in Vancouver is 94. Didn't know you could get much higher. I dont know why so many people are so gung ho about ethanol. The only benefit it will bring in its current state is slightly less dependence on foreign oil. Its not the environmentally friendly thing that the govenment and everyone else is making it out to be, at least not until they fine tune the refinnement process. I takes alot of energy and fuel to turn corn into ethanol.

we have 110 like a mile from my house in West Columbia SC

Have any of you ever pulled up behind someone doing ethanol/alchohol injection? Made my eyes burn not only in joy but damn that **** hurt. Thought I was gonna get an eye infection...

You must be talking about the station on the right when you enter Goose Creek from North Charleston! I live in the Creek. This gas works great in motorcycles too.

if your talking to me im talking about a shell station right off the west columbia exit of I-20...about 1.5hours from goose creek

Here in Ocala, Florida there is a Sunoco station that offers 100 and 110 octane fuel. 'The Ocala Pit Stop' is the name of it and its on SR40 and SR475A

Sunoco in lakeland Florida has 100 octane unleaded.

Really, got any specifics on where? I havent seen anywhere with higher than 91, and the local sunoco has only 3 tanks, and according to the color code on em 2 are 87 and one is 89, so they are lieing about 91 and 94 on the pump.

Just goto your local small airport and get some 110 aviation gas.

i don't know why you're concerned about getting high octane fuel, generally most cars aren't going to need anything over 90. in fact it can hydrocarbon build up in the pistons, heads and valves.

I get pump fuel at 103 and 110.

one place is down the street from the local speedway.

the other is the local small airport. small air craft run on 110.

Sorry, I was responding to Raiderfan

Camarounion, Just cuz..............Its great at the track, cuz you can run somemore timing....i really was'nt worried, but curious what was around the Houston are......Just thought some other people might know about some places I didnt.Thanks to all, Tom

There is one on 17a and Dorchester Rd.

The other is Buchlon <--sp? they sell the leaded gas, Remount and North Rhett area.

REMEMBER OCTANE IS THE EFFICIENCY IN WHICH THE GAS BURNS.

20% KEROSENE ADDED TO THE FUEL WILL UP YOUR OCTANE RATING 10+ POINTS. MORE KEROSENE MORE OCTANE.

REMEMBER THIS THOUGH, THE HIGHER THE OCTANE THE HOTTER THE STUFF BURNS AND IN TURN AT HIGHER OCTANE RATINGS YOUR TRADITIONAL ENGINE OF ANY KIND CAN BE DAMAGED.

Try ur local speed shop.If i can find the blue and red gas(105 and 110 oct I think)in jackson,MS you`ve got to have it somewhere around houston.I run 93 because of my chip and comp ratio that should be more than enough for you unless you want a little more power at the track

The local Marithon sells 100 I run a few gallons through from time to time. Also another local station sells 110 my room mate always runs his srt4 on it not sure what station..... Northern Il

we got 110 leaded and unleaded at pumps around here for "off road use only"

Well I dont think it burns hotter, it does burn slower, and I dont see how you could have engine damage from higher octane...Never heard that before...

I think he was referring to adding kerosene to your gas... which I dont think would be a good idea...as was stated most people wont ever need over 91-93 octane.

Doesnt burn hotter. You run higher octaine gas for higher compression motors. The compression creates the heat. Running anything over 93 octaine gas in a stock motor is pointless and a waste of money

highest i have seen around central Indiana is 94, and of course we have a few e85 stations that i know of, which is around 105 to 110 octane.

You know I just ask what was available in my area....I didnt want a motor lesson, or a chemical anylisis of gasoline, but thanks to all who replied to my origninal question....Tom

sorry dude, you just asked if anywhere was higher, took it as you wanted to know around the u.s. well at least you got your answer.

100 octane is available in limited places around here,

104 is the highest unleaded ive seen from sunoco racing fuels......its called gt104+ i think

honestly though, do you guys really need 100 octane+ fuel? my car is massively supercharged and it runs on 93

Thats because your engine has low compression....

The MAX you can run on 93 octain is 10:1/ 10.5:1

wow......you need to go back to school junior......thats one of the most ridiculous statements i've ever read....where did you get that from?

my engine was 11.5:1 when it was naturally aspirated and it ran mint on 93 octane for 4 years with zero signs of detonation.....pistons were like brand new when i took them out.

people have been as high as 13:1 on pump gas, with excellent results with well dialed in fuel injection, and the right cam grind. Lots of overlap in a cam pattern leads to less dynamic compression at lower RPM, and reduces your effective ratio and prevents any sort of detonation.........and thats how that works.

my engine is low compression.......at idle.......at 20+psi of boost, your effective compression ratio is WELL above 11:1, still doesnt detonate on pump gas.....why??? efficient heads, fuel system, good tune, and careful attention to timing retard referenced from boost pressure.

that being said, there is NO steadfast formula or number of static compression ratio which is the rule in determining what will run on what octane.

You dont have to be so defensive you piece of ****.

im not being defensive, im just pointing out that you made a ridiculous and incorrect statement.....theres nothing i hate more around here than the spread of bad/false information.

Ironic.

So much for the thread...

well the point was, you can get the fuel depending on where you are.......but what do you need it for???

granted if 100 octane was available at every station, id be tempted to use alot more timing on the street haha

I didnt ask whether I needed it or not, i was just asking a simple question about what is available in my area....It is my money, if I want to throw it away....I dont mean to be rude to anyone, but it was just a question out of curiosity....Once again thanks to all for the info..Oh yes BTW I love lottsa timing.....LOL......Tom

oh the joy of watching the good old octane talk go down the craper.......


Happens every time!
