If you are breaking the oil's viscosity down, then you probably need a different vehicle for whatever you are doing. That is EXTREME oil wear. If you run synthetic you could conceivably never need to change your oil. All you would need to do is refresh they additives. The base oil stock would be fine forever. That and change the filter.
Of course 'gap' sealing. Oil seals the 'gaps' between bearings. There is no metal on metal contact if you have proper lubrication. The zinc and phosphorus in the oil is the main protection against this. But it's protection is brief. Oil pressure is real protector.
Synthetic will help here. it is better at cooling, and it doesn't leave behind the varnish and sludge that dino oil will. Mostly because it's flash point is so much higher. A large part of what you are seeing in oil changing color is the oil itself changing from vaporization, not contaminants in the oil.
People have really been brain washed into the '3k oil change or you are a bad car owner!' bit. It's is well done on the repair industries part. 5k is easy. Figure how much money you will save over the life of a car. And I always do my own. I end up changing my trucks way too often, if it even gets it twice a year. Last year I put 7k on it. Most of it is winter driving, during the summer I can go 5-6 weeks between fill-ups.
