Hi, my obc show 1/4 mark of engine oil n at min should be 1 litre so at 1/4 mark should be around 750ml. But i fill up 1litre n it's show only 3/4 full so i top up again with 200ml still 3/4, another 100ml still 3/4. So how do i know is it faulty? Is there any dipstick to manual check? I'm driving a 2006 320i. Thanks
