When I refurbished my Heathkit HN31 "Cantenna", I refilled with 
FREE transformer oil from my power company's transformer 
shop. The trick was getting ONLY one gallon. I suggest 
calling your electric utility and asking.
Also, according to the info supplied by HK, for best performance, use transformer oil (http://www.tinyurl.com/wa7prc-cantenna). 
Actually, I no longer use my HK load for more than 100W (the 
resistor is rated only 90W). Instead, for > 100W, I use a 
homebrew air-cooled load that can take 1500W (at 100% D/C) 
all day: http://www.tinyurl.com/wa7prc-dummy.
