It seems to me that with the quality of today's oils, even 3,000 without a filter is not bad.
Oil lab results will give the best indication of what it should be. Most of us just don't do it.
Don't know if I am reading the report right but are they saying to leave the oil in and check it again in 5000 miles ?I sent my oil for analysis after a 3500 mile trip plus some local driving (maybe 500 miles). Mobil1 in a clean, recently rebuilt engine. I run a filter with a NAPA Gold element.
The analysis showed the oil was in very good condition, no need to change it on any of their criteria. See attached.
