In my last column, Unleaded avgas: You’d have to be insane to try to develop it (June 22 issue), I discussed the downside to the proposed lead phase out for aircraft piston engine fuels. But, like most things in life, there’s also a positive side to the issue.
I received numerous comments about my recent article on the bonehead editorial in another magazine that called for the removal of brain-dumbing lead from avgas (Misguided public opinion could end avgas, April 20 issue). One of the notes was from a Dr. Lyons concerning the futility of trying to replace leaded avgas. He also pointed out that the EPA is considering reintroducing lead in auto gas.
Jerry Quint of California, part owner of an aircraft with a Jabiru engine, wonders how to go about finding auto fuel that does not contain alcohol. He also wonders how to be sure that the fuel is alcohol free.
I recently received an e-mail from a gentleman who has an O-235 Lycoming and was experiencing a slight miss under some load conditions. He went on to describe all of the work he had done on the engine and yet the engine continued to miss under the same conditions. I gave the owner some suggestions on what to check, then sent the note to my good friend Paul McBride to get his expert opinion.
I recently received an email from Gordon Bowers concerning smoke oil for aerobatic aircraft. He was wondering what kind of oil to use and where to get it.
In my column in the March 23 issue, “”And then there were 10: As oil refineries stop producing avgas, what’s the future hold for us?””, I expressed my opinion of the future of aviation gasoline, noting “”there is concern that once the government starts imposing new regulations, it will go after anything that even sounds bad.””
James Missler of Bellevue, Ohio, is in the process of breaking in a Jabiru 2200 engine in his Kitfox. But he has a problem.
As oil refineries stopproducing avgas, what’sthe future hold for us?
In my last column, “”Multi-grade vs. single-grade oils: The debate continues”” (Feb. 16 issue), I recommend single-grade engine oil over multi-grade oils for use in large radial engines (over 1,800 cubic inches displacement). I am hoping that you all did not read that and conclude that if multi-grades are not as good in large radials, they probably won’t work in a 152 either. This is not the case.
n recent months I have had several conversations with the people at Precision Engines in Everett, Wash., about the use of multi-grade oils in large radial engines.
