100LL
Posted: Sun Feb 19, 2012 6:15 pm
Our USA tree huggers are suing to eliminate lead. It is also a market reality as there is only only one tetraethyl lead supplier left to my knowlege. At the same time there is considerable research on no lead avgas replacement fuel. In fact, there is already a turbine fuel replacement being tested by the military. A 100LL replacement is available in small (test) quantities and so far no drawbacks for most of the fleet. The sticky applications are turbocharged and radial engines.
Personally, I'd not worry about the fuel. Ben Visser (ret. from Shell) says that after 300 hours on 100LL they can be operated to normal TBO on auto fuel. There are to many stakeholders to phase out 100LL without a replacement. I like the Rotax engine (especially with the new 2000 hour TBO) and we have an O-360 in our long building Elite. Pick the engine that prrovides the performance you want and get on with building.
