I thought I answered it? The value of Mobil 1 is stretching the time between oil changes, in some cases dramatically. A BMW, just for example, can go something like 15,000 miles and 12 months between changes, making synthetic oil a terrific bargain.
Unfortunately, this is difficult for most people of a certain age to believe. So they change it early because they are nervous.
Of course, with something as important as motor oil, people should check their owner's manual--I would not trust the local mechanic or a random internet penpal on this.
