Oil is cheap, engines are expensive, IMO it just doesn't pay to go long intervals. Of course driving conditions have a great effect on oil life, I do mostly city driving, if I ran my oil 10k that'd be around a year between changes. You can tell an engine that hasn't had frequent oil changes by opening it up, they often have sludge built up all over, by changing the oil fairly regularly the engine stays nice and clean. That said, I would agree that the 3k or 3 months pushed by the oil industry is too frequent for 95% of all conditions.
