100 Octane Pump Gas

[danbike]

We just moved up to a far northern suburb of Chicago. Went in with the Marauder to fill up at the local Clark station. I did a double take. They have 100 octane gas at one pump.

Just don't ask the price. $4.40/gallon.:)

100 octane? That's a new one on me, and I'm not sure I'd have pumped it into the MM.

At $4.40 per, it must be some very special stuff.

I understand, though, as you get closer to the Wisconsin Dells, prices will naturally go up.

[CRUZTAKER]

There are lots of stations with pump 100 all over the nation. Most folks never notice them as they sit off by themselves and give the appearance of diesel or kerosene pumps.

We have several in our area, and I know of quite a few in the greater Detroit area. Most of the unleaded 100 CAM-2 pumps are at Speedway gas stations. That particular fuel is provided by Sunoco. I f one goes to THIS SITE (http://www.racegas.com/gt100locals/), you can find a location near you.

This 100 will not hurt your Marauder in any way. If you have a tune for race fuel, it can improve your performance on the street and track drastically by taking advantage of advance timing and the HP increase that results from that tune. Without the tune, you will likely only get better gas milage, and definately the exhuast smell from this gas is 'sweet delight'. :cool:

Those running Nitrous applications take advantage of the 100 as it presents little possibility of engine knock when spraying.

As far as price, it has always been $3.99 a gallon since I started using it 3 years back. Considering that 94 is now a whopping $3.85 around here...it's nice to see the 100 has increased so little.

No locations in TX. :rolleyes:

I agree with you Barry, If I'm gonna spend so much for gas, it might as well be 100 octane! :burnout:

[Joe Walsh]

Not to hijack this thread, but all of the Sunoco stations in my area (Maryland) seem to have dropped their Sunoco super 94 octane....
Is Sunoco 94 still available elsewhere???
What gives?
Any 'CAM'mers run into this??

[SergntMac]

Sunoco? What kind of crap gas it that?















J/K, I fondly recall the Sunoco 260 high octane from my younger years. Not many stations left around here.

[BillyGman]

Cruztaker is correct. Sunoco makes 100 octane unleaded gasoline. but just because they make it doesn't mean that most stations will carry it. I see it in a couple stations around here too, although in my homestate, no Sunoco stations offer the 94 octane anymore. Like cruztaker stated, 100 octane will not help your car, nor make it any faster, unless you have a specific race gas engine tune like some guys here have on their Marauders. if you do have a multi-position chip or a handheld tuner that includes a race gas engine tune, then you have to use atleast 100 octane gas in order to use that tune. As for me, I only use the 93 octane, both on and off the track.

[Jolly Roger]

Ahh yes,
Remember I do the old Sunoco 260.
Back when you could pull into the station and gas up the race car and the tow car from the same pump nozzle.
Those were the good old days.:)

Those were the good old days.:) Yep, I remember that "260" stuff too. If my memmory serves me correctly, the old Sunoco 260 was either 95 octane, or 97. I don't remember it ever being 100 octane, and it definately wasn't unleaded like their 100 octane is now.

[wsmylie]

Just saw a 100 octane pump a few days back near Chicago during my travels. It was at a Mobil station in the southside burb of Alsip, on west side of Cicero. Although the standard pump units at the station were labled Mobil, the high octane one (kinda hidden back near the kerosene pumps etc), was flying the Union 76 banner :confused: . Price was $4.99.9

Does 100 octane clog up your cats?

[Rkammer]

Yep, I remember that "260" stuff too. If my memmory serves me correctly, the old Sunoco 260 was either 95 octane, or 97. I don't remember it ever being 100 octane, and it definately wasn't unleaded like their 100 octane is now.I used to use Sunoco 260 all the time and there were 7 grades from 200 up to the 260. The 200 was either 98 or 99 octane but I remember the 260 well. It was 105 octane!!

We have the 100 octane pumps here in Orlando too. I have a race tune in my Xcal2 but haven't used it yet. Saving that for a cool night this fall or winter when I'll fill up with the 100 and take her to our local track. By the way, we can also buy 104 octane unleaded at several of the speed shops in Central Florida.

And, no, the high octane unleaded won't hurt your MM in any way. It's unleaded, that's all that matters. It just won't help it any if you're not tuned for the additional octane. :banana2:

[BillyGman]

Does 100 octane clog up your cats?I've heard that it's the lead in some race gasolines that can damage the cats, so if that's true, then the 100 octane gas that's unleaded, wouldn't do that. Just going by what I've heard on that though. I know that some high octane gasolines actually rely on the lead to obtain the extreme octane levels.

[SergntMac]

Does 100 octane clog up your cats?Only if it's leaded.

[Joe Walsh]

Can/Do they even sell LEADED gas anymore???

I know that they converted over aviation fuel to unleaded some time ago...
so the era of running up to the airport and having your buddy fill 'er up with some high octane leaded is gone too....

Oh hell yeah!

I find more pump 105, 110, 114 leaded race fuel than unleaded for the most part.

Alot of Citgos and Marathons carry pump leaded fuel. And every race track has leaded that varies in octane up to 118!

Why, just last week, Barb bought an off brand, ...:cat: Pus'nBoots, or some such, and our Seal point Himalayan, Hobbes, went on a hunger strike. :rofl:

[StevenJ]

Speaking of which, lots of stations don't carry 91. Today, I was lucky enough to find one and saved myself seven cents per gallon. The car is tuned for 91 stock right?

[Warpath]

You can actually lose power if you use too high of an octane gas. A friend of mine has a high compression bored and stroked small block Ford. He gained something around 20 hp by decreasing the octane of his gas. I don't remember what the octane numbers were. The higher the octane, the harder it is to ignite - hence why its used to prevent detonation.

You can also buy higher octane fuels including leaded versions here:

[SergntMac]

I remember Sunoco 260 in it's original formula from the mid '60s as 116 octane, leaded. Sunoco developed it for Roger Penske, who was developing a new engine for Chevrolet, the L-88. By the time the engine went into production, Sunoco 260 was available at the pumps. BTW, 260 got it's name from the temperature it would boil at, 260 degrees. Though I don't remember exactly why, back in those days, boiling points were as important to racing, as octane is to us today. Must have been a characteristic of racing fuel systems popular at that time.

[Bradley G]

Filled up with half 110 & half 93.
110 was $4.29 a gallon 93 was $3.25
already sounds different.
Any predictions how many miles I get on this tank? :P

I only see 94 on the NJ turnpike. Not around Harford County. But Barrys link shows 100 in the area:

This place has 98 octane not 100(is there much difference i dunno)and its at $6.19 a gal..
Also while i'm at it if i use 98 do i still put in the program for 100 octane fuel?

[HwyCruiser]

For the KC guys, the only 100 octane unleaded I've found around is at the Citgo in Shawnee on Johnson Drive, 2 blocks east of Lamar. $5.05 / gal :eek:. The cost has been keeping pace with the other grades.

I so wish we had Sunoco Ultra 94 around here. :cry: Best we can get is 92 octane BP/Amoco Gold.

[MikesMerc]

Does 100 octane clog up your cats?

If its the unleaded 100 octane that's being referred to, then no, absolutely not. CAM-II unleaded is as safe for your emissions legal car as is 93, 89,87, or any other unleaded gas.

Turbo Blue seems to be the "famous" leaded stuff Citgo carries. Its 110 octane and leaded...for race use only...and not for emissions legal vehicles.

That said, I know a plenty of folks that burn a tank or two of it from time to time even with cats in place. A tank or two does little harm. Repeated use will destroy cats quickly.

In Detroit CAM II unleaded 100 is still running $3.99. I use it exclusively now. Once you've picked up the 50 rwhp and 60 rwtq with the blower, its hard to go back. I do have a 4 position chip that allows for 93...but, with the perfectly emissions friendly 100 unleaded, I just can't get myself to use the 93 setting:)

[mpearce]

My 100 CAM2 is still $3.99. Interesting how that price stays solid, while others rise out of control. Unfortunately, Heathers Buick runs on VP, C-16...which I believe is 117 octane, and leaded. This race fuel has risen to $10.00 a gallon, and can only be purchased at a VP dealer (which we have plenty of in Cleveland).

[JRed04]

If anybody in chicago is looking for high octane stuff it is all over the south side. Gas cities carry Rocket brand unleaded 100, speedways have multiple levels of octane in leaded and unleaded. Like someone said they are usually in the back or in a seperate section.

[BillyGman]

Though I don't remember exactly why, back in those days, boiling points were as important to racing, as octane is to us today. Must have been a characteristic of racing fuel systems popular at that time.My guess would be because everybody ran carburetors and mechanical fuel pumps back then, and because of that, vapor lock occuring in the gas lines posed a greater potential for problems back then. It's my understanding that the potential for vapor lock in gas lines is far less with electric fuel pumps.

[Warpath]

...That said, I know a plenty of folks that burn a tank or two of it from time to time even with cats in place. A tank or two does little harm. Repeated use will destroy cats quickly...

My internal cumbustion engines professor in undergrad told us that it would be OK to run leaded with cats once in a while. The cats would eventually rid themselves of the lead. He didn't say how long or how often is OK.

That seems to make sense since mecanical pumps are on the engine meaning the fuel is sucked through the lines. The fuel would be at a low pressure increasing the chance of vapor lock. Electric pumps are usually in the tank or next to the tank and the fuel line is pressurized decreasing the chance of vapor lock.

[jakdad]

Ahh yes,

Back when you could pull into the station and gas up the race car and the tow car from the same pump nozzle.
Those were the good old days.:) Yep, we could get 102 & 103 at the pumps of any major service station. And yes, our tow cars or trucks required the same fuel as our stock car. However, some weeks we only had enough money to gas up the racecar.:D The upside is that if we put the car into the wall we could siphon gas out of the racecar and put it in the tow truck. Great life while it lasted!

:D :D

in california/////san jsoe we have a 76 station that provides 100 octain andits 7.99 a gallon are 91 oct ain is 3.50 a gallon thas cheap 4.99

I hate to resurrect old threads, but I didn't want to start a new thread since this thread already covers some of my discussion.

We CAMmers do not have the luxury I saw while in I was in Detroit for MV3...High octane UNLEADED Race gas available everywhere.

There are a few Sunoco stations that sell Unleaded GT100 (only 98 octane actually) for $6.50/gallon.:eek:

I just drove by a station that had CAM2 110 octane Leaded for $4.49/gallon.

I usually add 5 gallons of Sunoco GT100/98 octane to about 5 gallons of 93 octane in my tank before drag racing as a measure against any detonation...

I know that you are not supposed to run leaded gas through your Cats, but I could buy 3 gallons of CAM2 110 leaded for a lot less than 5 gallons of GT100 unleaded
AND get more of an octane boost as well.

Would the diluted leaded fuel still waste my Cats?...toast my 02 Sensors??

Any petroleum chemical engineers out there?

[Leadfoot281]

Lead is the last thing I'd want in my tank. It will deffinately plug up catalytic converters and foul out O2 sensors. Burning up exhast valves due to plugged up cats doesn't sound like fun to me either.

Why not run E85? That stuff is 105 octane. You'd probably need bigger injectors and/or a different "tune" but I don't see why it can't be done.

There is an article in the February '07 Car Craft magazine featuring a 8.6:1CR 35O Chevy with Vortech heads and a mini blower.

They got 601 hp @5700rpm's and 631lb/ft @3800 rpm on E-85!

They used a Quick Fuel E-85 carb, flat tappat cam, and a Magnuson 122 blower. Total cost? $6340.38.

[Motorhead350]

See a pump like that is what caused me to accidently go to the kerosene!
