E85 question???
I'm in Eastern N.C. and we have Sheetz gas stations. A year or so ago they started selling E85. I usually buy shell gas for my vehicles. I rode through sheetz tonight and its not called E85 anymore. It's called Flex fuel 51%-83%. Is this the same gas you guys are using as E85 or is this something different?

I guess they call it flex because you never know just the mix you end up getting so a flex fuel system will compensate for the variance nature of fuel mix they are bringing in.
E85 even at 40% is as good or better than must other fuel test comparison considered for high performance street use take a look at the tests conducted by the school of tuning Bob Morreale.

It's something different.
E85 must contain at least 70% ethanol and 85% at most.

Lowest i seem in my area is 84% and as high 98 % and my cars favorite out here in the lower south east.
I like the Holley kit cause is a flat bottom so will stand & brings a clear protector tube.

Yup legally E85 has to be at least 70%, i'm assuming you're tuned for flex fuel? You car will run whatever but just run differently according to what mixture you put in. I drove around town and tested different stations, I have one that is very consistent. Luckily its the station close to my house.

Current ASTM D5798-11 Standard Specification for Ethanol Fuel Blends for Flexible-Fuel Automotive Spark-Ignition Engine allows 51% for the minimum ethanol content of E85. It's been that way since 2011 or 2012. It's NEVER 85% ethanol.

I've been trying to research this as well. It seems from reading on this forum that many individual states have laws allowing different amounts of E.
From Light reading I've read in California where they're allowing the E content to go lower, so they can use it in colder climates. That means more hydrocarbons equals colder temperature starting. .
My concern is the hydrocarbons they blend with e are normally straight-run naphtha with real crappy octane. Any cheap, sweet naphtha stock unreformed that's just had the sulfur and nitrogen removed is used as blend stock.
I was thinking about starting a thread where we could collect results from various people testing the E content to build up some data.
Unreal has posted before where Arizona allows E85 to be as low as 40% e
