Just bought a new BMW diesel.Its free maintenence plan provides a free oil change every 12 months/15K miles.I'm planning to halve that (at my expense) to 6 months/6-7K miles.Unlike my previous cars this BMW's filter is right up in the engine compartment within easy reach.So...my question is...if I should decide,at intermediate intervals,to change the oil without changing the filter or to do the opposite which would benefit the car more? And I do realize that changing both would be best,but....TIA!
Also,does anyone know if the '09 BMW diesels come with a special "break-in" oil from the factory? I've read that VW diesels do.
