I ran into the issue of "paraffin oil" in the book on the Hungarian
HG I translated for Balázs Nagy. It turned out that similar
ambiguities existed in Hungarian as well, not just in English. What
we finally decided is that the stuff Balázs was referring to was what
we call mineral oil in the U.S., and that he wanted it to be distinct
from any sort of motor oil or other such substance that could damage
plastics over time... But paraffin oil or liquid paraffin are bad
terms because they can actually refer, as Colin points out, to petrol/
gasoline, mineral oil, liquified candle wax, refined petroleum
distillates used as lubricants, and kerosene. Even within the U.K.,
the terms are ambiguous, and when you include other English-speaking
countries, it gets only worse.

Funny, we had a discussion on the Northumbrian pipers list some
time ago
regarding liquid paraffin as an oil for the chanters and the
confusion that
causes - everything from petrol (gasoline) to candle wax.
