Can you tell us where to go read this article ourselves?

I also put about 1,000 miles per year on my truck but I change the oil & filter twice per year.
I'm not sure it's necessary to do that but I feel better doing it that way. From what I know,
it's the additives that affect longevity.

Best place IMHO is to read in the Oil & Lubrication forum here where you'll see references
to API (American Petroleum Institute) specs & ratings and such.
