We have a 300 watt oil pan heater and the engine starts much better and
oil
temperature comes up faster than when we used the FBO's dragon. The size
and weight of a portable generator that would power one of these is
similar
to the size and weight of a dragon. Why not buy the generator which would
have all sorts of other uses?

It's much easier on the fiberglass cowling, too. (I actually bubbled the
paint on a rental bird, using one of those "stick it in the cowling" jet
engine heaters...)

However, it doesn't warm the cylinders at all.

I wonder if a portable generator could power the cylinder warmers, too?
We've got the oil pan and cylinder warmers, and the oil is usually warmer
when we start up in winter (verified with our digital oil temperature gauge)
than it is in spring and fall.
