I think that a twelve mile drive would do a pretty good job of warming everything up in all but the coldest weather, which shouldn't last more than a day or two in your climate, which is pretty much like our's.
You'll see a few below zero mornings each winter, as do we, but it ain't North Dakota.

PP does have good starting TBN and retention, judging by what I've seen in the UOA forum.
The other George has done really well with his Accord doing what he originally suggested for you, although he's using dino, but he does live in a less extreme climate, which does help.
