There's a bunch of discussion of this on the interwebs, but this is a pretty good synopsis

In all honesty I feel the article is driven towards being an environmentalist. Which nothing is wrong with that. But I fail to see how it could be that detrimental to engine wear. If any it's mild, especially with our modern day motors and the technology behind them. It's no big deal for me.
I'll take over idealing over a blown oil cooler line fitting.
