Springfield Armory's stocks don't need oiling because they're in a temp and humidity controlled environment. Look at antique firearms, instruments, furniture. If it wasn't cared for the wood shrivels like Mr. Happy in the pool.
The 4:1 mix? That's basically "Gunny Paste" which is in reality a wood waxing recipe going way back before there where Gunnys.
I wouldn't use it because, well, why wax a milsurp stock?
