You're putting on a larger filter. A filter that's drawing in more oil, thus taking it from the engine. However your lubrication system need 6 quarts, so you add more oil. However it can only sustain a certain amount in the engine, before fouling your sparkplugs, or creating heavier leaks. At that point you're adding more, but just enough to keep it safe on the dipstick.

Now you have a larger filter, but it needs to cycle through more oil anyways just to keep it clean. At this point... You just have more oil to clean because it's all getting cycled through your engine, picking up gunk.

I don't know if my explanation is making sense so i'll try to break it down into ratios...

Let's say factory specs =

10/10 Oil/Filtration

Larger filter alone =

5/15 oil/filtration
Because the larger filter is carrying more oil, thus you're loosing what you need for lubrication.

More oil + Larger filter =

10/10
Now things are back in balance, you're just carrying more oil to accommodate a larger filter.

Now you have a larger filter... But it's cycling a greater volume of oil. Thus nothing changes. The only thing more oil is going to get you, is diluted dirt. Not as concentrated as it would be, therefore less mass, therefore more debris that will slip through your cellulose filtration.

I hope this makes sense to someone.
