[s-cars] S6 Mileage

[Steve Marinello]

You're right, Tom.  The bulk of the mileage decrease also occurred after the
move to Houston, home to smog control and ethanol.

After seeing Steve M's figure for mileage I came to the realization that I'd
forgotten the slow introduction of, but now, nearly, ever present dread
Ethanol into our fuel supply. I know that my vehicles get noticeably better
fuel mileage WO Ethanol. There are only two Ethanol free gas stations extant
in my general driving area, in Penn Yan & Utica NY. Both offer  89 Oct only
so I usually try to  have some 93 Oct in the tank for mixing. BTW If not
pushing the engine into full boost very often is 89 Oct OK w/MRC 2 or a
strict No-no? I've run it a few times and haven't heard any detonation but
my hearing is not the best!
