Where to find 100 octane?

[XYRCNCP]

Hey, I went to the Sunoco accross from my house last night (first night with the celi moving since the "incident" 2 1/2 weeks ago), and filled it up with 94 octane and went on a "test drive", it feels pretty good but it's only the first day. I know 76 gas stations sell 100 octane but there are none in VA, anywhere else? any suggestions? And, no I'm not going to the airport to fill up....hehe someone brought that up at the RTC meet, I think it was Jake....

Thanks

n e one?

I'm looking around for a link. I used to have one that had a station locator and the type of gas they sold. I remember some people saying that a few Sunoco's in MD had 100. Haven't seen it myself though.

Why do you want 100?

Because you can fill up with 93 or 94 then dump in 2-3 gallons of 100 and get like 97. Better performance and the engine runs alot better. I really think that the Celica (at least with mods) need more than even 93 can provide.

It's certainly your decision but have seen nothing to support any increase in performance from upping the octane.

I dont think that it will boost performance but I do believe the engine runs smoother with higher octane. With the high compression ratio a higher octane would help to prevent problems with running lean with an intake.

How would it do that?

You won't get much if any benefit from running a higher octane. I believe the octane makes the engine run hotter which can burn off some of the crud inside your engine. Other than that, I don't think you'll see a bit of improved performance, especially for the cost. Heck, at Sunoco it costs what .08 more for 94 octane vs 93? That's not even worth it. I can see maybe running 94 sometimes, but 100 is a stretch.

And don't put airplane fuel in your car! If you want super high octane go buy gas at a track where they have high octane for cars. You'll pay dearly though.

I don't claim it to increase performance, I just believe the engine runs lean with an intake and other mods. It just makes an engine run smoother, you should try it.

its because I like to do different stuff.....I certainly dont know if it improves performance or not, or if it has been proven or not, I just want to do it, just because.

I know my little Civic ran better on 89 than 87. Actually after using 89 for a couple months it ran better and better. That wasn't in my head, that was real. But I think there's a certain point where you're just dumping in extra octane and extra money and it become a moot point, and not worth it.

The GT-S and my Lightning both REQUIRE high octane. Yours due to the high compression ratio, mine because of the supercharger I presume. I don't know if I would get any additional performance out of it if I put higher octane in it. I know it wouldn't happen on one tank. I'd have to put it in every time over the course of weeks or months.

Another quirky side-note. My '88 MR2 Supercharged had a button in it depending on what gas I used. It had a "regular" and "premium" setting. The owners manual recommended premium fuel for best performance. It also said if you went from regular octane to premium to not use the "premium" setting until you had put several tanks full of premium gas thru the car. I'd imagine it must've worked with the ECU and adjusted timing or air/fuel ratios or something.
