Is it okay to soak a dirt bike chain in used oil?

I've never tried this but found this on ThumperTalk. A standard, non-O-ring chain.......... Just put a quart or so of plain old cheap motor oil in an old pot, enough to cover the chain and heat it up, don't need to boil it, but get it good and hot and leave there for about 5-10 minutes. No matter how well you think you may have cleaned the chain before doing this, you can watch all the crud and crap roll right out of the chain. Let it cool back down, take the chain out, let it drip dry, wipe off any excess, put it on the bike and spray it down with your favorite chain lube. Most of the time, even old filthy chians with kinked links that you can't get freed-up well will work fine after doing this.
