Interesting tales. Fortunately I have no such excitement! SAE 40 all the
year round.

Yes, its possible that there is a short somewhere that is getting hot,
but not in the right place to function as a block heater. I would
suspect that something else is going on, like maybe the oil viscosity
is too high. This would make it very difficult to start in cold
weather.

wife's car. I was thinking maybe the heater element could defective -
only part of it shorted out, but not enough to cause it to draw too much
current & blow a fuse.
It could test good while not providing sufficient heat to get the job
done.

If its much lower resistance than normal, then there will be something
very hot somewhere. Would probably end the short via blowing it,
leaving it now with an open circuit.

Power (heat) = V^2/R, so inversely proportional to resistance and

or a even just a smal boost in voltage will produce more power
(heat).
Of course, if the low resistance is caused by an internal short you
probably aren't going to benefit.
