She primarily only drives about 5 miles a day. We had a very cold December and January this winter season.

You can trust the OLM and the engineers that designed it, or strangers on the internet telling you to change it. Your choice.
Yeah, not totally sure about that. The last UOA I did for our 2.3 EcoBoost Explorer showed the viscosity had dropped well into the 20 weight category using Motorcraft 5W-30 for only 14 weeks, SUS 51.8/cST 7.82, from August 23rd til December 5th. The Ford OLM showed 58% life left on the oil. Yes, the wear metals were ok and the oil showed a TBN of 3.6 but what would they be at 10,000 miles or 0% oil life on the OLM? Just asking. OPPS! forgot that this was over only 4,275 miles.

So far he's been told to change it, don't change it and change just the filter. Since he can only make one choice, does he choose what a stranger on the internet tells him to do or trust the OLM? At least in your case you did a UOA and have something to base your decision on. In this case the OP,and everyone telling him what he should do,doesn't have even the slightest idea what condition his oil or filter is in. So, like I said, his choice is trust the OLM or a random stranger on the internet.
