All,
The real deal insulating oil is always the best bet and a lot of us used to use is Shell Diala AX. One of the reasons folks are now having a hard time finding it it because it has been discontinued and replaced with a "better" and less expensive oil:
SHELL DIALA OIL S2 ZX A
This insulating oil is available in most communities just find the Shell Jobber or wholesale lubricant distributor in your area and see if they have it in 5-gal pails. If you are in a small town you might even be able to get a few gallons from the local electrical utility personnel.
This oil has also been used in lapidary operations as well as a substitute for cutting oil.
Regards,
BrianB

However, I noticed something just the other day and I thought I would throw it our here to the impressive collective knowledge of this list. I was pouring some bar and chain oil that I happened to have for my chainsaw lube into the lube reservoir of my newly acquired drill press when I noticed that this oil has the same light yellowish color as well as low viscosity and identical odor to the oil that I usually run into when opening up pole pigs and x-ray trannies. I realize that since it's not labeled as "dielectric" or "transformer" oil, it probably doesn't have the same stringent no moisture standards as the Shell Diala and such, but I was just wondering if this would be a suitable substitute for the "real McCoy" if one found a minimum 55 gallon drum (or even a 5 gallon bucket)
