I'm about to change the oil on my 2004 330i ZHP for the 1st time (myself) in between the regular recommended service interval. I'm using Mobil 1 and a new BMW filter. I had observed a BMW tech change my oil last time and he placed some oil within the filter area as well so upon start-up, there would not be any delay in getting any oil into the engine. My question is that I'm not quite sure of my memory on this one and need a bit of advice... once the oil filter is removed, what is the proper way to install the new oil filter in regards to making sure there is still oil within the oil filter container?
