Proper torque !?
Fasteners that have sufficient vibration and can work themselves loose over time generally specify some sort of thread locker. Typically smaller ones where you cannot get sufficient torque without breaking.
I have greased all my lug nuts long ago...
Woah! This can be danger zone! Torque specs are given for dry fasteners, not lubed.
When engineering, a formula is used to convert torque from dry to wet. Most anti-seize brings torque specs at least 20% lower, down to potentially under half of what the dry spec would be.
Torque is used as a proxy for clamping force. Torque is easier to measure than the better proxy (bolt stretch) or best method (directly measuring clamping force).
Some anti-seize brands list what the torque reduction should be. See here: Bostik Brochure. Torque reduction values are listed starting on page 3.
Interestingly Permatex does not recommend reducing torque values for their Anti-Seize PN: 81343.
My grandfather recently told me of a home brew that is a 50/50 mix of acetone and ATF. I haven't used it myself. But him and his friend swear it works great.
I use this in gunsmithing all the time. I tend to use aerosol PB Blaster, aerosol Liquid Wrench or whatever I have around for car use though just for ease of application.
