I do lot's of highway driving. Most of my trips are 90 miles. This gives thorough engine warmup and very few cold starts per oil change. Warmup is where most damage occurs anyway.

But, this said, I still can't buy in on 10,000 mile oil changes. I don't care what kind of oil, what kind of service, what kind of oil filter, or what kind of engine. If you have leased a car for a few years, of course, change it every 10K, or even less frequent if the factory recommendation allows it. If you buy a car to drive for many years, you need to wear out the oil drain plug threads before anything else.

I will restate my unscientific study here; 3,000 mile interval, oil drain hot and overnight, oil filter every time, got 380,000 miles from engine.

My $0.02,
Change oil hot and change oil often,
