Correct, WIX and NAPA are owned by the same company. I could probably find out who actually manufactures the Nissan OEM filter...Mahle is pretty big in that space for passenger car applications, but I'll ask around. When it comes to filters, oil/lube filters especially, the principles are not going to differ much between light duty and heavy duty engine applications. You want a filter that has a good balance between efficiency (particle removal capability), capacity (how much contaminant it can hold) and flow restriction. In a lube system, the wear particles of concern typically fall between 15-30 microns...and the limiting factor of service intervals is the oil itself. Oil oxidizes due to the combustion process, and as it oxidizes, the chemical additive package depletes and the oil loses its ability to keep wear particles/contaminants in dispersion. The oil will begin to agglomerate over time and that's what will begin to plug your lube/oil filter. That being said, oil chemistries have gotten a lot better in recent years...that's why oil change intervals are commonly double, or more, what they were when a lot of us were growing up. In the heavy duty space, oil changes for many class-8 truck OEMs have jumped from 25k miles back in 2010 to as high as 80k miles for 2020 models. In terms of how that has changed the filters over time, Cummins Filtration has been using synthetic nanofiber materials in several of their OEM lube filters for the last ~5 years...meaning no cellulose (paper) or micro-glass media types in those products. Nanofiber and melt-blown synthetic media types are not made with glues or resins and are able to provide higher efficiencies, higher capacities and lower flow restrictions than those legacy media types of cellulose and micro-glass which provides more benefits to the engine. I'm not really aware of any nanofiber applications in passenger cars today, but again the requirements of passenger cars are so much less than heavy-duty engine applications and their respective duty cycles.
