HA! What do you think as a company would do if they offered free maintenance for 2 years? ...Extended drain intervals would save Toyota money if they have to service your car free for 2 years. BMW does the similar at 15K intervals but then again they offer 4yr 50k free maintenance. But seriously most fully synthetic oil is totally capable of those types of drain intervals. Some brands like Amsoil claim even longer then that. Personally im a anal person and i don't mind doing oil changes so i do them every 6K with Synthetics, you can say i waste money, but for me i like that piece of mind and the feeling of fresh oil in my precious 2UZ
