the STC to bump our O-540 to 250HP does not allow auto fuel
autofuel is not allowed in any STC'd aircraft if the autofuel contains
ethanol
there is not much autofuel that does not contain ethanol

Tetra-Ethyl Lead

If I had an aircraft that required 100LL, I would read every report from
Innospec, the only manufacturer of tetra-ethyl lead (TEL). Here is a quote
from their 2007 third quarter report, available on their Web site:

"In Octane Additives, operating income for the third quarter was $2.3
million, compared with $10.3 million a year ago. The gross profit margin
was
50.6 percent, compared with 55.7 percent a year ago. Revenues of $16.2
million were down 49 percent from a year ago. The reduced results in
Octane
Additives primarily reflect a shift in certain shipments from the third to
the fourth quarter, as well as the continuing longer-term decline in the
tetra ethyl lead business."

The report also shows that Octane Additives sales were $16.2 million out
of
a total revenue of $143 million, about 11 percent.

Given the declining sales, declining profit margin and the large costs to
decommission a [TEL] manufacturing facility, if you were in charge, how
long
would you continue production?

What's the alternate fuel situation for Pawnee's?

Bill Daniels

Hi Bill;

There is an autogas TC for the Pawnees. However, we stopped using it
when CA replaced MTBE with alcohol.

If they went out of business, there woulds be 80% of GA affected. I
would not worry about it, or perhaps just use our winch!
