Ditto...seems way too much for a drain plug and more like a small
car's lug nut torque, IMHO
What does the shop manual (not glove box manual) say?

I use a 12" ratchet, tighten it till it stops, then hit the end of the ratchet with my hand till it moves about a quarter to half an inch. Never had a leak, or anything else.

Specs found here say 18 ft lbs for oil drain plug. I can't imagine any need to crank 62 lbs on a drain plug!
On edit, The list I linked to are for 2011-2012 trucks. I see the torque specs under the 06-07 trucks on that site do show 62 lbs, but I suspect it must be a misprint. Maybe it should have been 26 lbs?

All of the other drain plug specs say 26 or 27. I'm betting it's a misprint in the manual. Maybe GM owes you an oil pan.
I'm glad I never bother to break out the torque wrench for that bolt. I don't want to get it dirty. I just make it tight. It's been fine for 7 years so far.
