Why do you take a bath more than once a week? To keep clean?? An oil change is cheap, engine damage ain't...For normal driving, I would go with the 2 to 3K between changes. But if you are driving 20 to 30 miles at 100+ when you are out, you are breaking the oil down much faster and I will error on the side of clean oil. Also, when you live in areas of high humidity, you are fighting moisture. An oil/filter change is the best maintenance for longevity for any internal combustion engine, so why take chances.
