Bio-diesel, Unleaded & Ethanol is the key

Apparently I'm not
the only one blending "bio-diesel" and gas.

To bad they don't know the correct
oxygenated carrier(s) to boost it another 15%....

FUEL ECONOMY STUDY: (E10AK)
Unleaded with 10% ethanol denatured with iso-pentane and bio-diesel "The three
vehicles averaged 1.5% lower mileage with E10, 2.2% lower mileage with E20, 5.1%
lower mileage with E30, and miles per gallon actually increased by an average of
1.7% when using E10AK made with the specially denatured ethanol. E10AK was the
highest mileage fuel in two of three cars."

Read and study all that you want...

However, the added BTU boost that Bio-diesel gives Ethanol makes it somewhat
competitive.

“On Headline News’ on CNN, one of the bits of advice for fuel efficiency was to
not buy gasoline with ethanol,“ Jennings said, speaking to the group at its
first program day on Aug. 17. “We’ve got to get the word out and the facts
straight.“

Kasperson compared results with five fuel regimens, showing lower average gasoline mileage, compared with unleaded:

E10--1.5 percent poorer mileage
^{(compared with unleaded).}

E20, 2.2 percent lower; ^{(compared
with unleaded).}

E30-- 5.1 percent lower; ^{(compared
with unleaded).}

10AK (10 percent ethanol denatured with iso-pentane and biodiesel).

Average results were:

unleaded, 7.08 cents per mile;

E10, 7.0 cents per mile;

E20, 6.85 cents per mile;

E30, 6.88 cents per mile;

and
E10AK, 6.79 percent per mile.

Put another way, $20 in fuel would allow driving 282 miles using unleaded;
288 miles with E10; 292 miles with E20, 291 with E30 and 295 with E10AK.

--2005 Chevrolet Impala with a 3.4 liter engine:
Showed just over 1 percent lower mpg on E10 and E20, but actually gained over 5 percent on the E10AK blend.
