Lug nut torque specs?

My torque wrench specifies that it should be zeroed out before storing.
You shouldn't ever lubricate the threads.
From tirerack.com:
Under- or over-tightening wheel-attaching hardware can be damaging and dangerous.
Torque specifications are for dry threads only. The fastener threads should be free of oil, dirt, grit, corrosion, etc. The hardware should turn freely without binding when tightened by hand. It is important NOT to lubricate hardware threads or seats. The friction at which torque is measured against should come from the hardware seats. Lubricating hardware threads and seats alters the friction generated at the lug seat which will result in inaccurate torque readings and/or over-torqueing of the hardware.

Nope, not in 40 years.

A little information before you decide to lubricate the lugs:

Bad Idea?

You want to store your torque wrench at 20% of full scale. Many quality wrenches have stops built in so that you can't approach zero. If you have a tilt block style wrench and try to completely unload it the floating tilt block will drop out of position and make the wrench inoperable.

This is close enough.
Torque Tables

Our Lance calls for 110# to 120# torque for aluminum wheels. We check them before each trip and also during our trip.
Be sure to set the torque wrench back to zero when done using it.

Yes, I use a torque wrench. The torque depends on the size of stud, they type of wheel, etc.

Kinda like saying, "how much air do I put in my tires". Without more info, there cannot be a correct answer.

You should have your rig info on your profile page. Yes, you are correct, the lug bolt size, and a few other things enter into proper torque. It surely is not a one torque fits all. A light trailer, with smaller lugs/lighter axle may just need 70-75 lb ft.

I'm pretty sure my 2016 Gulfstream has 7/16 studs. I wouldn't go to 90 ft/lbs on them, that seems high. If I had 1/2 or maybe 12mm, but not 7/16.

Good idea to store your new torque wrench at the zero position.
