Lug nut stud grease

gear oil works just fine

 

I prefer the Lucas Marine grease on tie rod ends,ball joints etc.Blue color so you can see it.Very water resistant if you drive thru mud puddles etc.

 

Nope. Just plain ol' oil does the job.

 

I've never seen a shop apply grease to lug nuts. They are supposed to be torqued "dry", and lubing them up could cause over-tightening, thereby stretching and weakening the studs. If the shop doesn't torque it and just uses their 1" gun to beat the lug nut into place, AND they greased 'er up first, I'd be having them pay for new lug studs, nuts, and potentially even wheels.

 

Wheel studs are one of many locations on vehicle that are torqued DRY. Read your manufacturers specs.

 

Technically speaking you're supposed to put a drop or 2 of oil between the cone and the flange but that's it. I never put any kind of lube on the threads. Might quickly hit the studs with a wire brush and brake clean/blow gun if they're dirty or rusted.

 

The flange washer style lug nuts that you see on all the trucks now are spec'ed for a wet torque with a drop of 15w40 engine oil between the nut and flange washer and on the threads, these are the only lug nuts that use a wet torque, all others are dry torqued.
