San Antonio is a far cry from Fargo in regards to gettin cold.
Its late May in TExas, just how hot does it have to get before I can get the full 85% eth?

You say its no big deal,
but my black rubber parts disagree... they didnt like the amount of gas in the E85 I had last fall,
and the plan is to mix it down to end up with a little gas left in it as we can get away with.
So starting with twice as much is a pain.

Like Kero said,
I plan to mix up some E85 16% castor, which ran the engine last fall,
and blend that with regular glow fuel at 1:1 or maybe 2 (E85/16oil) + 1 (Glow10/18).
The less gas content I start with, the less gas my rubber parts have to put up with
