Yeah I run full synthetic in the BMW and always have.
It gets changed every 7500 even though BMW claims it can go for 15K.
Of course BMW never said 15K on oil changes UNTIL they came out with "all maintenance will be included with new cars under warranty"
When they started having to pay for it they doubled the oil life.
Porsche claims 20K on Mobil one.
Guarantee you if I had money ( or the inclination ) to drive a new 911 it would get 4 oil changes in that 20k miles.
Diesels 10k is pretty much the norm on light duty use.
