Winter blend for E85. Essentially E85 will never truly be E85. It's more like E70-75 during the summer time.

Yep I agree, you will never know unless you test using Fuel-It Test Kit before though.
Since July i've tested from E80 to E90 (Valero, CITGO, OmegaFuels, Shamrock, and others)
OmegaFuels pump is the more consistent

I agree that testing with an in-line sensor is the only way to get an accurate measure of the in-tank blend. My question then becomes, how do you start to formulate an idea around the "octane" available for a blend when you have mixed 93 (at 10% e) with some variant of E (also mixed).

Maybe I am making this more complicated than it is but if we assume true E85 is 105 octane and yet we know we are likely never getting straight E85 from the pump, how can you then compute the blended octane?

For me this is more about being able to document and track how the car runs with varying degrees or E blend (octane) at specified boost/timing levels.

They are in his signature. I actually found it awhile ago just searching the Play Store.

Cjindna, yeah the in line fuel sensor is nice so you know what you're actually running but it's still hard to get the right mix you want when you don't know what is coming out of the two pumps, premium and E85. It would be nice if you actually got 10% and 85% ethanol respectively. I know Fuel-It sells a test kit but I can't imagine standing at the pumps testing fuel each time I fill up.

My feeling exactly. Plus the one time I did test it I made a big mess. So now I let Rob test it and go to the station that he tells me is best.

Problem with that one is that it doesn't take into account whats already in the tank.
