Autogas in winter makes starting much easier due to its higher vapor
pressure.


I have heard a lot of arguments about vapor lock, but I do not understand
how vapor lock could ever be a problem in a Cessna 182.

With the high wing configuration, the carberator will always have a positive
fuel pressure due to hydrostaic pressure. How can vapor lock *EVER* happen
in a Skylane? As an engineer, I don't see it happening.

Now, on the other hand, if you have a low wing airplane with a fuel pump,
then vapor lock is a very real problem.

But vapor lock in a high wing carberated engine.... not possible.
