This Fram XG3614 was used on a 2008 Toyota 4 Runner with the 2UZ-FE 4.7L V8. It was ran for 1 year and 18,027 mi with Mobil 1 EP 5W-30.
Based on my UOA results I am sticking with this combo for 1 yr/15-20k mi.

Wow, same size 3614 oil filter on my 2.0L hybrid engine (which only runs for half my miles....) as on this 4.7L V8 (which runs for every mile and idles too).
I put a 3600 oversized Fram Ultra oil filter on my 2.0L, so I guess I could go for 40,000 miles theoretically on a Fram Ultra especially. hmmmm... maybe?
Nice, good comparison! Do you by chance have an ultragauge or scangauge? I'd be interested to know what your average speed was and how many hours the oil is in service on a typical OCI. I short trip my Tacoma a lot and change the oil every 6 months at 2,500-3,000 miles and ~180 engine hours. My average speed is about 13.8 mph.
That's just a little over 620 hours on that OCI. Further proof that most of us could use an oil filter (on a clean engine) for 2-3 typical OCIs pretty easily. Is there room to run an xg8a on the 4runner? There's clearly nothing wrong with what you're using, but more media surface area typically results in slower/more even flow over the filter media, slower flow is said to result in better filtration. A bigger filter would also help keep the filter out of bypass on cold starts, as well as having more contaminant holding capacity, not that that's an issue here. A larger oil filter would also add some extra oil capacity, a good thing if you're extending your OCI.
I did a search and found this, shows the two filters side by side.
