Default USGI Gun Oil Question

I recently stumbled across these little cans of gun oil. I have seen the PL-Light oil before, and i noticed that these are PL-Special when i got home. I started to look on the internet to learn the differences but there doesn't seem to be any obvious sources. Does anyone have any info or links to resources where i could learn a little about the different oils the Soldiers used back in the day?




Thanks

Special is the low below freezing oil. Used on a few different things then guns. But definitely for guns too.

Ever since I found what the Japanese used in the pacific, haven't used anything since.

That is what I was thinking he was alluding to, but I'm wondering where is he getting whale oil today...

I have some old ATF from the 60's...Before the EPA came along I Heard whale oil was the base stock for ATF....This could be a sea story....I wonder if the are any old time motor heads around that can share the truth....The July 1940 FM 23-5 specified RLO, neatsfoot oil, and whale oil...regards....alex

Think HC is correct, whale oil was also the additive used in positraction/sure-grip rear axle lube.
Gotta remember the whales pre-date the oil wells!

Default Rifle grease

Hayes O. always has original 1963 Grease cans for sale for $20. I bought a can and like it. Plus the can looks cool in the shelf. And works good to "age" new parkerizing or black manganese jobs.

The cans are about 12 items down this list:

I don't know what the Japanese used on their rifles - probably anything they could get.

But as to whale oil being used in Automatic Transmission Fluid, I have heard the same thing from my Dad who was an Automotive Engineer. He said that the reason they called the product "Dexron 2" was that the original "Dexron" formula included whale oil which had been banned - so they had to come out with a different formula ATF that would work in all the older cars as well as the new ones.

Sperm whale oil was included specifically to prevent corrosion of transmission parts.

Interesting history of ATF:
