The E85 movement, which is based on an alternate fuel consisting of
85% ethanol and 15% gasoline, is getting an additional boost thanks to
a recent decision by General Motors to expand its existing line up
from 9 models to 14. This increase will mean that General Motors,
which already has nearly 2 million E85 vehicles on the road, will be
able to produce as many as 400,000 E85 vehicles per year. For
proponents of alternate fuel sources, the decision by General Motors
is certainly a welcome one. Let's take a look at GM's expanding E85
fleet and what this could mean for you, the fuel conscious motorist.
E85 has been around for well over a decade now, but has only recently
has it been the focus of such widespread attention. Credit gas prices
exceeding $3 per gallon for interest in E85 and you can see why
General Motors is continuing to expand its line up to meet the demand
for alternate fuel sources.
The Current Line Up
GM's current fleet of E85 vehicles now numbers nine. GM's Silverado,
Tahoe, Impala, Monte Carlo, Avalanche, Sierra, Suburban, Yukon, and
Yukon XL currently make up the entire fleet of E85 capable vehicles
produced by the automaker. The bulk of GM's E85 sales have come since
2000, however the automaker had been building E85 capable vehicles for
many years prior to the turn of the millennium. DaimlerChrysler and
Ford also build tens of thousands of E85 vehicles per year....

We rented an E85 capable Suburban in the Dakotas last year. I only
found a couple stations that sold it and the E85 reduced the already
dismal 16mpg to somewhere around 10. It was the same price as the 10%
ethanol gas they sell up there.- Hide quoted text -

It's tough to beat the btu in a gallon of gas.

With propane the simplist, cheapest mixing valve will work as well as
the best fuel injection. Stuff is 100 octane, as well.
The stuff _is_ available many places. Slightly more BTU per pound
due to the slightly higher proportion of hydrogen. I had propane heat
at my previous address, and adding a fitting or two and a hose to the
1 000 gallon tank would have been easy. If I had had a 100 octane hot
rod I would have done it. Gas does have higher energy density but that
may not necessarily matter. It does with planes, more so than cars and
boats.

Gas still has way more btu per gallon which is a lot more energy density.
Propane is one of the lowest with only 92,000 btu per gallon. Gas is
123,000 btu per gallon. Octane only helps you run a higher compression
which you could argue lets you make better use of the fuel. But in that,
diesel can run pretty high compression and it is the one fuel with even more
btu per gallon than gas, 138,000 btu per gallon.

BTU per pound is considered more useful. Never seen a published figure
for energy content that wasn't by weight. Per pound, propane is
slightly better, although in practice the heavier tank would cancel
that. The pilots have always figured gas at six pounds per gallon,
while propane is about four.

Every October it starts again. The oxygenated gas hits the pumps in the
Wash DC area, My city mileage goes from 15 MPG to 13 MPG and my highway
mileage goes from 20 MPG to 17 MPG. I pay the same per gallon of "gas"
or whatever it is that is coming out of the pump. But, I'm still putting
the same amount of crude into the atmosphere.
