No. Petroleum will destroy o rings.

it depends on what the o-ring is made of. nitrile is petroleum safe. but latex/rubber will harden and become brittle if exposed to petroleum. most silicone is also incompatible with petroleum (and also incompatible with silicone lubes).
i think Maglite recommends using petro jelly for their o-rings but they're the only one's i've seen.
good lubes that work safe on anything, like Superlube, can be pretty cheap, so don't risk it. check the lube discussion thread, if you haven't yet, for more info.

I've found that "Manteca" by the 5lb. drum to be the most economical flashlight lube. It can be purchased from any Mexican-themed grocery store or Michoacana. Just be prepared to fight off the wild dogs and stray cats who will desperately try to claw through your clothing to get at your lights. Besides the occasional raccoon attack, I've been very satisfied with it's performance. Crisco works too and attracts less animals....

Seriously though, I got some of the Eagletac "Lithium Complex" lube from lightjunction. Its small, but you really don't need that much.

There are some very good lubricants, but petroleum jelly is not one of them because it will harm most o-rings. Look here: http://www.candlepowerforums.com/vb/showthread.php?242414-Comprehensive-Grease-and-Lube-Thread
