The gas price thread is a good one about everyone's attitude about the price, but it got me to thinking (dangerous, I know)-
Where else do you buy the higher octane fuel besides at the track?
What fuel are you running- 98 unleaded, 100 or 110 leaded?
What race gas prices are you seeing where?

I run a 50/50 mix of 110 leaded and high-test pump gas.
I live near NY City, and am having a harder time finding race gas suppliers these days. I usually just buy at the track, but one of our local tracks (Pocono) doesn't supply race gas at track days, so I have to buy beforehand when I go there. I used to be able to find service stations located near my route to Pocono, but they all seem to have closed. There are suppliers around -- it's just not as convenient as it used to be.
You can find suppliers at www.racegas.com (Sunoco race fuel) and www.vpracingfuels.com (VP race fuel). Note that VP is quite expensive.

110 octane here. Ran Sunoco in the past but switched to VP as it is more consistent according to those "in the know". The respective websites will list distributors.

My engine is a race engine that has a highly optimized combustion area. I'm in the process of going up to 13.5:1 and will also run 93 octane fuel. Obviously it would make more power on 100 unleaded, but it currenly makes the same as a PMNA slide valve engine on 112 octane.

I've heard the same about VP compared to sunoco, but it was from a VP dealer, so...

Yes. I'm not an expert but from what a number of the formula car guys say is that it's not as good as track gas. A couple of HP and you really should tune your car to it to extract the best out of it. Also there are the legal grey areas about it with regards to non-aircraft use. While they say it is low lead (LL) it is still very high in lead content.
I know number of guys who run it and have no problem with it in their FF and FC cars.

Leaded fuel will clog up an O2 sensor and it will eventually go bad. I proactively replace them annually on cars that run leaded fuel.
Av Gas is no good for race cars. It is designed for cooler temperatures, steady state RPM, and other factors not encountered in a race car.

Do you want to tell me all the brands of wide band sensors that you don't use, so I can know which brand you do use?
