[Milsurplus] Bird Termaline oil

[Mark Foltarz]

 I am cleaning up a Bird Termaline 8890 in preparation for working on my GPT 10K and I realize it most likely needs some oil.I reach out to Bird and ask for  a modern equivalent to the part # indicated in the manualThey cheerfully send me to a link ( Bird RPK8890-3, Coolant Kit | Bird RF Online Store (btgstore.com) )  for the oil.The kit only costs $1300 for 3 gallons of oil - and a gasket.I couldn't believe it. Anyone have any advice about a lower cost replacement for the oil ?I was thinking of using the MFJ transformer oil for loads.
