Fuel/Water, Bearing/Rust

[Dwayne & Nancy]

Bob, Joe said that blaming water in the fuel as the cause of bearing
rust was a “folk tale”.  The cause was the fuel decomposing into acetic
acid (vinegar).  The decomposition is caused by the catalytic effect of
the brass components inside the fuel tank.  Joe tried leaving bearings
in several brands of fuel for four months without any rust forming.  You
should read the magazine more carefully.  You can’t tell when something
valuable with show up.  <VBG>  Dwayne

Okay - Matt - since my MA already found it's way to the shredder....

The diatribe of the last week or so on this list has been, shall we say,
rather........ interesting, (except for the news about Kirk Gray, that's
plain sad). It's time for something new. 

In this month's Model Aviation, Joe Wagner talks about experiments he
has run with a trusty old engine. He ran baseline performance data with
his regular fuel and then he added water in his fuel to see how badly
performance would be affected. His results where very interesting. Shall
we say that he made chopped meat out of that "sacred cow".

He also briefly touches on what really is the root cause of bearing
rust. Even the uninitiated should find that interesting. Could a
solution to all of your OS bearing woes be this simple?

There, that ought to whet your whistle.
