Since c85 requires more fuel to hit stoich, my bet is its just e90-e98. Not going to be less corrosive unless perhaps they put in some sort of additive. E98 could explain the better cooling effect that they proclaim. Could make a little more power. Probably way overpriced.

Mr. Fred-
In the recent DSport magazine article that was mentioned earlier, the testers found that the C85 sample that was used was measured at 80% ethanol as compared to the nominal 85% ethanol from their control sample (Propel brand pump IIRC).
Not sure what accounted for the increased power or fueling requirement. Check the article out for more info.

Interesting. Maybe VP was suggesting that since most e85 at the pump is more like e75, their 80% ethanol would require a bit more fuel for stoich. New new guess is that instead of being mixed with regular gasoline like pump e85, its mixed with either premium or their race gas.

Im about to switch from Sunoco E85 to VP's C85 so interested to hear what people say on this thread, and when I have some dyno figures (early next year) I will report back

There is no pump c85 it came out for a while then disappeared so we have to buy tinned from either VP or sumoco (ango american oil)

I thought the big claim is consistency from the VP fuel. I test every batch of E85 I get from the pump. It always goes into cans/jugs before the car, so I can easily sample and test it. My station during the summer is always 85% ethanol. Never bought in winter... because racecar.
For me, I don't see a need to spend 3-4x on fuel when I can do my on QC and be confident in what I am running.
