What filter is that? I bet it'll fit on my QR25DE.
In most cases, Yes. For example, with the OEM filter on my VW GTI, the oil capacity is 4.8 qt's. With an oversized Mobil 1 M1-301 filter, the oil capacity is exactly 5 qt's.
Whilst you can't fill the filter to the top you would be surprised how much is held in there if you do pour some in. I think it helps even in situations such as yours. Certainly better than a completely dry filter.
The filter manufacturers do have a disclaimer that if you use a different filter than the one they specify for a given model, they will not cover any resulting engine damage . . . I assume that means even from a defective filter.quote:

Sorry for not getting back quicker. In Mobil nomenclature, I use the M1-110, which is the "tall" filter for the G35's install of the VQ35DE. The M1-108 is the size that Infiniti specs for the car, and this is the filter that's so small you could fit two of them into a soda can. Of course, all things in perspective, the 110 is hardly "large" itself, so in this instance, I'm unconcerned about delays in oil flow from filter size. Besides, when essentially the same engine appears sideways in the I-35 (Maxima in disguise; the G35 is a much more heavily disguised 350Z), Infiniti calls for the 110 size filter anyway. Why the difference, I don't know; there's plenty of room in the G35 for the 110 "tall" filter.
Do whatever you can so the filter is at less than a 90 degree. Use ramps, jack or park it on a hill so you can get more oil in the filter without spilling it. I don't have the issues you do in regard to the filter but my drain plug is on the drivers side and on the side of the pan. So I park perpindicular to the driveway on a slight hill when I change my oil.
I can quote one instance where larger filters actually helped with a design flaw. Chrysler 4 cylinder 2.2l engines used in most everything sold in the 1980 and 1990s used a very small filter. Only problem was that the standpipe on the engine came very close to the end of the filter and would starve main bearings of flow. Solution was to use a fl1-a equivalent so the standpipe was not right at the end of the filter and could flow. Chrysler put a different stand pipe on later engines to fix the problem. If you had an early one, it likely died about 80-90k miles.quote:
