Also got some 0.1 here all made by rubycon.
If they have no use in audio I will move them on, but I know people go crazy over paper oil caps, but don't want to hoard too much stuff!
They are rated at 1500V, so may be useful in high voltage circuits that use transmitter tubes perhaps?

Those old Japanese oil caps are rather notorious. Anyone restoring a 50's or 60's Japanese-made receiver is usually advised to replace them all. Unless you have a way to measure leakage, I would not use them in any critical circuits.
Unfortunately, old PIO capacitors are suspicious, as paper deteriorates over time. Measure for leakage before using them.
Beg to differ. Dry paper capacitors indeed deteriorate due to moisture infiltration, but PIO don't have this problem. I have 1930s PIO cans that have no detectable leakage current at their working voltage. I use 5 uA microampermeter for measurement.
Ok, good to know. I'm not sure what applications these oil caps typically have. But I know some audiophiles think they "sound" better.
I had a bunch of 0.1 I sold some time back of a different brand and they went for silly money.

Yes most definitely, I have a bunch of those mustards I use in guitar amps, and I won't let them go for any amount of $$$ anyone throws at me!
I replaced all the Japanese oilers in my Sansui 1000A with vintage US mil-spec oil caps. I harvested most from broken old military equipment, but some on epay. I use oil caps in speaker crossovers exclusively. Never had a failure, and all test right. I often parallel oil signal caps with Russian teflons, (but I won't buy from Russia now). Had a couple 50 uF, big can power supply caps that were dented and leaked a little PCB stuff. An old guy was asked, "What if you get the oil on your hands?!?" He said, "I wipe them off." I soldered up a couple of the square cans, and gave others to hazardous waste. I've found that if you don't drop them, they don't leak. Vitamin Q's go on ebay. ;>)
