[TowerTalk] Oil for Dummy Load

[Joe Subich, W4TV]

Check the properties of peanut oil before you use it.  I can't quickly
find the breakdown voltage for peanut oil ... dielectric constant is
slightly higher (3 vs. 2.2) and dissipation factory almost 10 times that 
of mineral oil but it may not be an issue in this application.

Some of the literature seems to suggest Canola oil but Soy oil seems to
be the base of choice as "eco friendly" replacements for mineral oils
(e.g. Envirotemp FR4).
