Lugs, studs, torque, and antiseize

I've used antiseize, the aluminum one from Permatex, since I worked for a
Porsche Audi dealership close to 30 years ago.  In fact, every line
workstation had a can thoughtfully supplied by the parts department.  I have
yet to lose a wheel because the nuts (or bolts) came unthreaded.  After I
left the employ of the dealer, I worked for an independent Porsche service
shop in West Los Angeles where we did a LOT of timetrial and autocross prep
work.  We used it there, and I'd venture a guess that those of us who left
there to operate our own shops all still use it on a daily basis.  This is
empirical reporting, not scientific testing, and time trial cars in the 70s
weren't the PCA club racing cars of today, so my experience and opinion
might not apply to all out race cars.  However, torquing a lubricated
fastener provides a more consistent and repeatable result than does the same
procedure on a dry example, IMO, and I think that yields a better result in
the long run.  I NEVER use oil on the threads, as it tends to carbonize and
you end up with stuck fasteners, IME.  Until I'm conclusively shown the
error of my ways, I'll continue to use anti seize on wheel lugs.  John
