Absolutely correct. The cheapest SL rated oil and even a Fram filter will get you where you want to go in terms of mileage (100,000-200,000 miles) if you change them every 3000 miles. Been proven thousands and thousands of times.
In a moderate climate, yes, I believe this to be true. However up here it's been pretty cold this winter, this morning it was only -5F for instance. In this case, "any old oil" will not protect very well. And given the number of extremely cold mornings like this, I would say that an engine running one of the crummier conventionals with poor cold weather performance, would see quite a lot of engine wear over the wintertime.
