anyone ever use Sunoco GT100 gasoline?
Discussion
While Sunoco does sell the GT-100 under the CAM2 label, they specifically call it "CAM2 GT 100". The original CAM2 was 110-octane, highly leaded and was purple in color. It's still available under the CAM2 label or GT-100 as "Standard Leaded". I found a few links as well which includes a locator for GT-100. Below is a good one.

They also state that the GT-100 is designed for modern high-performance cars including exotics, etc. and will not harm catalytic convertors or Oxygen sensors so it should be safe in the Lotus.
They do have a source nearby (for me) at Moroso Speedway in Palm Beach County (Florida) so I might be tempted to check it out.

Once through my full tank of Sunoco 94 I am going to give it a try. Will post the results on this forum with a week or so.
Spoke with Sunoco race fuels today about the GT100 gas and they say there is no harmful metallic compounds. I specifically asked about MMT as well and they said it contained none. MMT is an ingredient in some octane boosters that apparantly can foul sparkplugs, sensors and the catalytic converter with some kind of red oxide. I also asked, and received, the name and number for the local distributor in my area. Just as a further check I made sure he sold the gas to the station. I again asked about the metallic compounds (I am a bit compulsive) and got the same story twice. The CAM2 GT100 gas is available here in New York City from a station called Sonomax (Greenpoint, Brooklyn). Never heard of the company. Told the local distributor about my reservations using an unknown gas station with my expensive new car. Said I had nothing to worry about, but that it is not impossible, that an unscrupulous station owner could blend it with a lower octane fuel. In any case, the car would not be at risk in this circumstance. Said that if I was still worried, the way to make sure it is the real deal is to bring a clear jar to test the color. The color is "crytal clear, like water".

It would appear that Sunoco is moving into Palm Beach county (Florida) at a high rate now. Where I've never seen one in more than 15 years, they seem to be moving in. There must be a dozen up and running or in the build process right now. I checked and they only have 93 octane, no 94 (boo, hiss....). But Moroso Speedway has the GT-100 fuel. I should call and get a price. I might try a tank of this after the next service where I'll be replacing spark plugs, air-filters, all fluids, etc. and resetting the ECM as well. If you try the GT-100 please post your findings.

Well, I tried the 100 Octane fuel. Gone through about half a tank so far. Why has it taken me so long to post my findings you say? The car seems to run considerably leaner with the fuel and the colder weather, and as a result, running through half a tank has taken awhile longer than expected.
The setting is an seriously industrial neighborhood with warehouses, factories and old cobblestone streets. It is almost dark out. The largest sewage treatment plant in the Northwestern US is located directly across the street. The gas station is absolutely huge and primarily used by the 18 wheelers the pull in after dropping off their trailers. Coming here has taken a little courage, but it is the nearest and only location I know of that sells the stuff. Making me more self-conscience about where I am, I realize that I had just polished my jet black 2003 Esprit with some riduculously glossy show car polish (Zaino's - if you have used it you know what I am talking about). The only sign the fuel is made by Sunoco is on the pump handle itself where it is marked "Sunoco Race Fuels - GT100". After putting in my credit card, it dawns on me that this gas costs $5.50 a gallon. Is this possible, do they mean 2 gallons? I soon spend about $50 and the pump stops as it is the maximum the pump will charge to a card at any one time. To my embarrassment, at least 2 gas station attendants and a truck driver come to my aid, as at this point I couldn't figure out why it stopped pumping. The gas station attendants can't speak a lick of english. Conversational english was not a job requirement apparantly. I wondered silently whether they were the benefactors of nepotism of the very large Indian station owner peering out from the store. After the truck driver explains, I spend another $20 topping off the tank. My wife who is still sitting in the car cannot beleive I just spent $70 to fill the car or why it is has taken so long.
After making a spectacle of myself, I turn the ignition and the engine sounds different right from the start, it sounds a little less barking-mad than before. This immediately concerns me; after all, how could it sound less aggressive with $5.50 gas in the tank? Driving up the street, I notice that the engine, contrary to my expectation, is not more edgy at all, although it seems to pull a little harder. After driving several weekends now with the car, I can say this was not the wrong impression. More power feels present but not in the way I expected. Power is there throughout the revs and at all points delivered in a velvety punch. The engine seems to be a bit more free revving as well. Lastly, if you don't like hearing your engine pop and burble as you lift off the throttle and decelerate, don't use it. It does this frequently. This is caused by the engine running leaner (hot as hell in the exhuast pipes) and the raw fuel being dumped by lifting off the throttle (which ignites easier than regular fuel) igniting in the pipes. If it weren't for the muffler I am sure flames would shoot out the tailpipes like a race car.
Luckily, I like it.

Way to go, looks like you may have to invest in a small tanker of the 100 Octane for the back yard fill-ups
Closest I am running to you is BP 98 Octane Ultima Fuel, which I put in last weekend for a track day. Makes it slightly more peppy but didn't notice a massive difference in performance. I have been told you can see flames in my exhaust when I am really booting it, but had pops and crackle sounds running 96 which is my regular fuel anyway.
I have been told running aviation fuel will cause corrosion in our fuel lines eventually??

You should be safe with the aviation fuel Kylie if it handles the 96.
The 96 in NZ is among the most aggresive on fuel lines in the world. There were a lot of vehicles with dissolved fuel lines and carbs when it was introduced with 58% aromatics (toluene, benzine etc) Now it is below 50% so not so bad. The fuel lines in my sisters VW dissolved, fortunately I noticed the fuel dripping under the fuel tank.

Does the avgas in New Zealand contain lead? The 100LL (low lead) avgas hear in the U.S. would not be suitable for cars with catalytic converters as any amount of lead will poison the catalyst.
By the way, in the mid-west some Conoco stations carry 93 octane. That's the highest I've found in Oklahoma, Texas and Missouri so far.

Have you ever thought about this stuff?

I believe they have a location in Fort Lauderdale. I have just heard about it and haven't looked into it really. Supposed to be quite safe...

Well, I've not tried any of the higher octance fuels in the Esprit yet. Moroso is listed as a distributor for the Sunoco GT-100 and they're not too far away, but at $5+ a gallon, that's a rip... IMHO. I used the 100LL Av-gas for years when I did a lot of motocross riding as the octane is high enough so that the 2-stroke lube (you gotta mix it manually) doesn't drop the octane so badly. It also allows for better performance (re-jetting) and keeps the engine burning much cleaner.
I still would not use 100LL is any vehicle with Catalysts as the amount of lead there would still cause damage to them (cats). I'll have to look into the link you attached and take a run down and check out the pricing, etc. Come to think of it, the lotus club has the Poker Run to the keys on December 6th-7th and we'll be meeting at Foreign Toys in Ft. Lauderdale. If I can get there, I'll let you know what I find out.

Well have been running 98 now for well over a week after a track day and after several hours of long driving. I am finding that the engine is running smooth but more fuel is being dumped and igniting in the exhaust when I button off the pedal, people driving near me must get a fright 
. My car is tuned to 96 Octane according to my Lotus mechanic and will run 98 and 100 no probs, but not any higher >100. I just checked in my exhaust and its gone from a sooty black to a charcoal grey colour, so must be running better. Am very tempted to splurge out and put 100 in it on the next fill for that light pale grey colour.
