This is just pure supposition, but follow me:
1) Ed's Red starts with Kerosene and ATF. Those two components make a pretty handy gun oil mixed 50/50
2) Does ATF ever freeze? If so, are there Automatic Transmission Fluids that don't?
I would think that 50/50 Kerosene and ATF would make a good gun oil for any temperature, low or high.
Just wondering. By the time hit hits 15F, my freezer is full of venison, and I don't come out until Spring Gobbler Season.
