My torque wrench goes up to 250 ft. lbs. Not sure what you mean about "lubed", but are you saying that if I put some kind of "lube" on it, I can drop down to 280 ft. lbs. which I think I could do by "overtorquing" with a cheater bar and my present wrench?

What it means by "DRY" is dry clean threads, noil oil or lube added. "LUBED" would be the threads lubed up with Never Seize or Molycoat paste.

Thanks to all for the info. I just spoke with the manufacture tech support group. They said "the 380 ft. lbs. is critical" and advised not to lube. They suggested checking with a mechanic shop which I will do. I will also try an auto parts place to see if they rent these.
