Interesting Oil Change View

I've read that and other similar articles before,...

I have pushed back my oil changes from 3000 miles to 4-4500 thousand miles,...With the exception of my wifes Pontiac which mysteriously vaporizes 2 quarts between 3500 miles and 4500 miles (her onboard monitoring says 48% remaining),...and Mom's Neon which only gets 2000 miles a year and only see's short trips, resulting in oil which never gets hot enough to completely dissapate any soluble contaminants and moisture....

I still only buy non synthetic oil cause its cheaper by half or more,....
