"... if these (BMW N20 4-cylinder turbo engines) are well maintained, these can be very good. The problem is, well maintained, by dealers or manufacturer standards, is not the same as actually being well maintained. Because BMW recommended a 10K miles (16K km) oil change interval on these engines. In my mind, that's too far. That's way too far ...
I'm not saying you should change your oil every 3K miles (5K km) like you did in the 70's and 80's. But 10K miles? Uuuuuuuh! These are 4 to 5 or 6K thousand dollar engines. Oil changes are significantly cheaper ..."
