Neat link Kero
Summer Blend: Class 1 (min 79% ethanol)
Spring/Fall Blend: Class 2 (min 74% ethanol)
Winter Blend: Class 3 (min 70% ethanol)
I stopped by the station and asked what was actually in the tank, 70 or 85 or what.
We all expect the twinkie at the counter to not know, thats ok,
and she took the correct action when I asked
... she yelled over her shoulder to get somebody that might know.
When we explained that the E85 has different seasonal blends
the manager type person tried to figure it out
but quickly realized she had no idea what I was talking about.
So she then did the reasonable thing, and called a hard workin guy over.
That is where the story heads south.
The workin guy didnt know,
but he wasnt going to let that stop him from making me accept his BS on the matter.
He just kept repeating that E85 is 70% or better,
and depleted his vocabulary finding new ways to say 70% or better,
regardless of me mentioning the summer and winter blends.
So in the end, I had to leave the station being told that E85 is ALWAYS "70% Or Better",
and nobody in Texas gets anything different.

note:
the link Kero gave lists south Texas as NEVER should get the winter 70% blend [&:]
