The article talks about BMW's oil analysis computer, but thats just one
company. In europe for the MY2000 vehicles VW cars, they now come with a
similar computer. The vehicles are filled with a 0w30 VW 505 oil ( mobil
1 for example meets VW 505 ), and the computer tells you when to change
the oil. They achieve similar numbers to BMW, city drivers change around
10,000 miles and mostly highway drivers the computer tells them around
18,000 miles. Porche and MB also recommend pretty high drain times as
well.

The 3000 mile or 3 months thing is something left over from the days of
poor quality oils, and poor quality engines.
