At the risk of sounding like a broken record: I used Mobil 1 for years and years, usually with a Mobil 1 or Wix filter. I changed it at 3000 miles religiously.
After switching to RP almost 2 years ago in both my Grand Cherokee Overland and Ram, I tried going to 6000 mile intervals to offset the cost. My filter choices so far have been Wix and Purolator Pure1. At the 6k oil change, the RP looked cleaner and more like when I put it in, than the Mobil 1 ever did at 3k!
I've never sent my used oil out to be tested, but the naked eye tells me the RP is protecting better at 6k than the Mobil 1 did at 3k. Obviously these filters were also still doing their job, and quite well.
I'd say you would be perfectly fine waiting the 6k and changing both the oil and filter together...
