My personal feeling cars with DI leaving the filter behind well in my opionion only add to you fuel dilution problems. I be changing that filter out on every change on my new Mazda.I still say the MityVac is a good solution. Swap the filter every 2nd or 3rd time.
Flip the switch and expel the dirty oil into your recycle container.
Easy peasey. In fact, too easy peasey.
