E85 @ 105 Octane (25% @ $2.85) + 'Premium' 93 Octane gas (which at most pumps is actually E10) (75% @ $3.85)
It works out to an effective Octane rating of 96.
I've done this twice now, when in the area to get E85 - both times, post fill up, for about 5 minutes / miles, my 96 LT1 drove poorly, idled rough, and actually stalled once! But, after the PCM compensated, it was fine.
Took about a 1.4 MPG 'hit' too.
(I've decided that the best place for E85 is in my Meth tank!)
