Everyone with oil temp issues

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.
