Another Ethanol Free gas thread where is the 93 octane anymore?

With a volt I am stuck buying gas that costs about $0.50-$0.75 a gallon more but I am aware of various sources stating the volt quits pulling timing around 96 octane.

Back in the good old days I could actually buy 96+ octane unleaded NON-OXYGENATED (all gas is oxygenated regardless of if it is ethanol free) gas at a couple of local pumps.

I can't find that stuff anywhere but did find LEADED 110 Octane fuel, useless.

So I am setting my sites lower, DO ANY WISCONSIN STATIONS SELL REAL 93 OCTANE?

I can only find it in 10% variety and oddly a wash or cheaper than 91 octane.

I did find 92 octane at one walmart but it doesn't state anything about may contain up to 10% ethanol but likewise doesn't say it doesn't either.

Any ideas? Folks are saying my low volt gas MPG is because I run 90ish octane with 10% eth, I want to run a few tests but can't find any stations selling real Super Premium.

Odd goes mid grade -> Super Premium 91 (odd that used to just be premium, super was 93)

Cheers
RYan

Check airports and boat harbors in your area. I found a small local airport with 93 octance unleaded about 20 miles away.

I am aware of that but boats this time of year is a no go and the airport pumps are behind a fence, will have to see what happens if I ask the stupid question.

Probably get a stupid answer.

Look for a blender pump to get E30 93 ocatane, or blend your own 1 part E70 2 parts E10/87. Others are running E50-60 in volts without problems.

Looked on E85prices and couldn't find many blender pumps in WI so going to have to blend your own.

I ran E60 and the fe went down, ran e30 FE went down.

The trouble with ethanol in this area is that it is the same price as normal gas and it doesn't positively affect fuel cost in the winter.

I will try it again this summer, I am thinking a WAI is really needed on the volt.

Ah well.

We had blender pumps in 2006, but a few years later Utica? Unica? got bought out by some GB firm and all the cheap mid grade ethanol blends went along with it.

How did $/mile go? E85/70 price swings so much vs E10 it changes quickly. My FFV 20% seems to be a good point, but maybe a car requesting premium it's lower?
