That being said the car only has 80k miles now, so I guess we'll see long term signs of damage in the next 30k miles.

My friend had a brand new Mercedes not two years ago whose manual recommended 12,500 oil change increments.

There is a message here - 3750 mile oil changes under normal driving conditions (no tracking, etc) are not necessary. Obviously, Mercedes has a lot of confidence in their engines from not breaking down given their 12K mile oil change intervals. I have the same confidence in the Nissan engine, my 355 SBC, '03 Sport Trac and John Deere LT150. All use Mobil 1 and the oil is changed once a year irregardless of the mileage. But that's just me and my 35+ years doing my own maintenance and repairs. Hey, why pay $100/hr labour rates when you can DIY?
