Jim -

I wrote an article on winter operation that was published in the Dec
1986 issue of Sport Aviation. In it I posted a chart of the approx
max dissolved water in PPM in aromatics and non-aromatic fuels. It
was based on some sketchy data I got from Amoco.

The amount of dissolved water increases with temperature. The point
that I was trying to make in the article was that severe chilling will
cause some of the water to precipitate out of solution as snow, which
can quickly and effectively clog the fuel screens.


Now if you used mogas with 10% Alcohol that wouldn't be a problem. Of
course there are a few inconvenient side effects from the Alcohol.

It seems to me if they can make the car engines stand up (more
specifically the gaskets and O-rings) then they could do the same in
aircraft systems.

Which brings to mind the question: How does anyone in Michigan use a
Mogas STC? Our gas is not labeled as to whether it contains Alcohol
or not. The pump sticker only states, "Meets Michigan fuel standard
(something or other) call this 800 number for specifics or
complaints", or something to that effect.
