From what I've read, the wide operating range synthetic oils (e.g. 0W-50) use components of standard mineral oil to keep them thin at low temperatures. Thus, they don't have the longevity of a synthetic with a smaller 'window' like 10w-30 which doesn't have as much or any mineral oil component.

Yep, that's true. The wider the range, the more prone an oil is to thermal breakdown. I'm just going to stick with 5W-30, install an oil cooler (at my next oil change) and be done with it.
