Is anyone able to speak to the relationship of oil usage to oil change interval? If a car is LEAKING oil, that, if anything, would lengthen the change interval (since the leaking and filling represent a succession of mini oil changes). But, one time when I was listening to the Car Talk guys, they made the point that when a car is USING oil, you should actually change the oil MORE often than you would otherwise. But I foget their reasoning. Anyone know what the logic would be?

Thanks.
