I have changed the oil once in 7 years. My car has 12k on it. It still smells like new!

Classic example of a situation where someone doesn't understand what kills engine oil.. How about fuel intrusion? coolant intrusion?
The oil in that engine should have changed at least once per year, EVEN IF THE CAR WASN'T BEING DRIVEN!
Based on what I have seen, I'd bet the engine posted above would be at higher risk of experiencing an IMS issue or some other engine issue than most any other 100K mile engine that had been driven by a teenager.
Lack of use IS ABUSE!
To the poster bragging about the 7 year old service:
Do an oil change and send me a 1 liter sample of that oil. I'll analyze it for free, I'd pay to see the acid numbers that oil has!
Extended drain intervals are one reason why these engines are seeing failures and thats not just in terms of mileage..
