Well at least oil is a known screwup.
Ethanol from corn seems to be screwing things up in a new way which isn't
any better. Somehow affecting hunger. You think folks will get pissed if
they have $5 gasoline, wait until they are hungry or paying $5.00 for a can
of corn or $20/lb for hamberger because the corn to feed the cows is too
So now we are being screwed by oil and by ethanol.
What's next? Biomass sourced ethanol sounds better but it is a long time
off. The corn farmers will fight it tooth and nail.
I guess I misinterpreted Dad when he said it didn't miss a lick but
okay, thanks for correcting me. Your further explanation (omitted
above) about the performance of ethanol makes sense to me tho I have
no facts or experience to back it up. Even in my present cars I can't
notice any performance sacrifice but that's only because I don't drive
them hard anyway so I probably can't notice it therefore.
Thanks for your info and correcting my errors (and to Dad too).
It's worse than just that. Since the ethanol is oxygen bearing, the
O2 sensor will detect its presense as a lean condition and the ECM
will richen the mixture. Thus, you use more fuel and pollute worse.
I live right on the edge of the rural/city boundary and have been able
to choose to buy "city gas" with 10% ethanol or normal fuel at home.
All my vehicles get noticeably worse mileage on ethanol mix.
Plus, while running ethanol fuel, I lost a drag race to a Subaru
Impreza WRX so it must cut the C5's power by at least half ;).
But I am not a chemist.
Can't speak to the C6 but I do have some C4 &
C5 experience that tells me we are hunkering
down a dumb path. Excess amounts of this
stuff causes brain damage.
First off: I favor occasional, small amounts
of ethanol -- from an Oak barrel, aged 8-12
years. Also OK in malt beverages or in a
glass of wine. Also good for sterilizing the
skin prior to a blood draw. Don't care for
Everclear or for putting it in my gas tank.
As a Californian, I pay a good share of the
tax hit to support the current 'Ethanol
Party.' It's a sort of charity since the
stuff doesn't transport well enough to add to
the California fuel supply. We use just
enough to replace the MTBE that we lost a
couple of years ago. (6-7% Ethanol blend is
typical here). For this we take a 5% hit on
mileage in comparison to when we used MTBE.
BP is working on ethanol from Calif.
sugarbeets which will probably put the screws
to our beef industry. In exchange for this
"good deal", BP and Shell want to drop the
refining capacity in this state by 10% --
another good deal at the pump.
In addition to federal taxes, I also pay at
the pump since total gasoline consumption is
higher and our cost of gas augmented with 6%
ethanol is about 10% a gallon higher than
what most of the U.S. pays. So, there's not
much to be said for the goodness of Ethanol
out here. Oh yeah, the air is dirtier since
we started using this stuff. (and the Feds
have been yelling at us for a couple of years
over that problem.)
I think that -rev's 50% hit on C5 performance
may be a bit high but, I notice a definite
performance hit on desert hill climbs with
the C5. The enrichment that -rev is talking
about is significant and probably saves the
engine. On a hard climb, using Calif. fuel,
I occasionally hear that single ping as the
retard takes effect. Never have that happen
coming back home with Nevada or Utah fuel
even though the return trip is usually more
"heat soaked" with higher loads on the engine
As rev says, "it gets worse..."
Our Ethanol-drunk politicos have cut off the
major research dollars for an MTBE
replacement. Such a replacement would have
given us cleaner air than ethanol, better
fuel economy and for the C5, better
hot-weather, uphill performance.
Get a good read at:
Halvorson does a good job differentiating
between pre-L98, L98, LT1/4 and LSn cylinder
heads and sound fuel choices for each.
No BS, just Halvorson's opinions based on
sound science and experience.
