Having read the guide below & having changed oil on loads of cars in my time I'm thinking of doing an intermediate oil change on the 325 as I do a lot of short journeys.
Anyone got any recomendations on mileages etc & whether it's worth doing or should I stick to the interval on the display. Cars done 4K so it's not a huge mileage yet. Was thinking it may be of benefit to put fresh oil in to get rid of anything from the "run in".
All comments appreciated.
