My classics would love that stuff. Iron headed high compression big blocks... Ping!
Sunoco now offers 94 Octane

I used to run Ultra 94 in my dirt bikes/four wheelers when I was younger. Haven't seen it around forever.

We have had 94 octane in Canada for a very long time. When we had Sunoco they brought it out back around the mid 1990s. Then when Sunoco left here and was taken over by Petro Canada they kept selling Ultra 94 ever since

My VW could use it no doubt
Well they have almost made it back to premium octane. When I work on a Pipeline years ago it had to be 95 everything 92 or lower was regular.
93 AKI is recommended for a lot of high performance cars these days. Some street-legal cars can even take advantage of up to 100. The first time I'd heard of it was when looking through the owners manual for my 2004 WRX. 91 was recommended for mine, but it listed a recommendation for 93 for the STi.
100 AKI can be found. 92 is typical premium in most states and gets closer. Not sure why 94 other than they can (typically at a premium. Apparently 93 is the typical premium in some states or some gas stations.
The only time I've ever seen 94 was at a Sunoco station while I was in vacation in Florida back in 2006.
I know about 93. I was asking why 94.

Many newer (for example GM LS engines) your engine will have knock sensors or similar style of ECU strategy.... in short the computer is constantly trying to run as much ignition timing as possible. It does this by periodically bumping the timing up until the sensors detect ping. Even a bit more than 93 octane will allow the computer to run more timing in a stock engine in most situations (if your engine uses this strategy, early LS engines certainly do. I have seen it while datalogging and DIY tuning my 2004 Tahoe with the 5.3.)I know about 93. I was asking why 94.
Basically the computer doesn't know the octane level of the fuel, and it doesn't care about the real number......it's just trying to run as much timing as possible all the time. Whatever octane and conditions allow is what you get. A bit more octane will always help if your motor uses this strategy.
In NJ, Sunoco always had 94 and it was called Ultra 94. I used to get it once in a while in my S4. When I would head up 95 from VA, there would be a Sunoco that had Ultra 93 as the highest. Now, in NJ the local Sunoco station also says Ultra 93 with an option for 94. Weird how things changed.

I have no idea. The strange thing is that one of the few places I knew that had anything higher than 91 had 94/96/98/100. Any of it was blended on the spot with 100 AKI racing fuel. So they could have rigged it for 93 to reduce the cost.
Weird because I am also from NJ. Sunoco Ultra has been 93. They just recently updated their own website regarding 94 octane.
Maybe it was just the Sunocos by me? I'm up in Northern NJ in Morris county. The 2 closest always had it with the one also having some 10x octane race gas. I can't remember exactly what it was though, maybe 101, 103, 105????
I remember back when you could get Sunoco 260 using the custom blending pump....
You are correct about the racing gas that Sunoco offers. However, that is only at designated locations. The 94 Octane is now or soon to be offered everywhere at Sunoco locations.
Weird man. I used to get 94 all the time in Denville. My S4 is a 2001 to give you a time frame.
After eating, you have to wait half an hour before driving into Canada.
Not doubting you. But Sunoco just recently implementing it on their own website so it is now official.
