I have experienced the shock you are getting from breaking loose frozen lug nuts. It usually occurs if the wheel has not been removed in a long time, at least over a year and if it is over torqued. Most of my daily drivers have their wheels removed twice a year for winter/summer wheel changeover so it is normally not an issue.
I have used all kinds of stuff on the lug nuts like, anti-sieze, wd-40, etc. and I have never had an issue with "tensile" strength... Altough I have heard that these lubricants may affect the true torque applied when using a torque wrench.
Like everyone else has said, use a torque wrench when installing the lug nuts and you should be ok

here is how torque is measured for studs:
The actual force experienced by the stud is given by the formula:
F=T/([P/2pi]+[uT*rT/cos a]+[uB*RB])
F=tensile force on stud
T=applied torque
P=thread pitch
uT=coefficient of friction between threads
rT=radius of thread midline
a=30 degrees for common thread
uB=coefficient of friction for the bearing surface under fastener
rB=radius of bearing surface midline
Adding lubricant significantly reduces uT and uB, resulting in larger F for a given T.
i'm not saying that is doesnt work or wont work-I was just stating what many of companies, and manufactures have stated,obviously for a reason. Do research son.
