Shell reveals unleaded avgas
New formula 10 years in the making
SHELL AVIATION, a subsidiary of the multinational oil giant Royal Dutch Shell,
announced that its 10-year effort in the laboratory has produced a fuel that may put a
long-sought goal-once thought to be unattainable-within reach: a lead-free "performance drop-in" replacement for 100LL that could power any aircraft in the piston fleet.
"That's our definite goal," said Michael Sargeant, avgas commercial aviation manager
for Shell Aviation. "We've tested it and had some exciting and successful tests."
The lead-free formulation has a motor octane number (MON) above 100, a critical factor in formulating a fleetwide fuel that could power high-compression engines.
(Octane prevents premature ignition known as detonation, and is measured by more
than one scale.) Shell's new lead-free formula has passed preliminary tests in Lycoming engines on the ground, and a Piper Saratoga recently flew for about an hour on the
fuel-the first of many tests that will be required for certification.
The FAA has a goal of deploying a lead-free piston aviation fuel by 2018, although
Sargeant said the company may be able to achieve required approvals and start distribution sooner. "We believe two to three years might be possible," Sargeant said. "That's the
timeframe that we would love to work towards. The details need to be developed."
Sargeant said another design goal is to keep the retail price similar to avgas, although
it is too early to know exactly what the new fuel would sell for. Shell has only just begun
conversations with the various regulatory agencies involved. The fuel will be submitted
for approval from the FAA, ASTM, and the European Aviation Safety Agency.
Shell is now among three companies that have announced unleaded formulations that
could replace avgas in piston aircraft in a matter of just a few years, pending additional
testing and regulatory approval. Shell is by far the largest of the companies known to be
developing unleaded aviation gasoline. Shell's research team has been focused on finding a single fuel that can work for all, rather than a multi-fuel approach with different
formulations to meet varying engine requirements.
"The industry doesn't need bifurcation," Sargeant said, noting that the company envisions making it possible by licensing or other means for other petroleum producers to
manufacture and distribute the formula, which is made from existing components and
will not require major changes to the production and distribution infrastructure.
"We think the secret going forward is really working with as many experts as possible," Sargeant said.
