Reflex is right - it's fairly temperate here in what is basically "Portland Oregon". The cold spell (15-19F) was pretty unusual, mid-30s & up is more normal. One the the folks I correspond with (cj, on the TDR Forum) has two dodge diesel pickups (04, 05) and lives in much colder climes (Montana). He's running a similar blend, and did Ok for the most part but finally put heated systems in. I think the source was coolant, to keep the oil warm in-tank and up to the engine.
For filtering, after letting it settle a few weeks, I pour the still-liquid oil into a drum and blend. When I'm ready, I've a portable fuel pump (local farm hardware store item) with a 5-micron whole house water filter (string spun element) followed by a cannister diesel filter. Things get filtered on the way into the tank. cj has a much more elaborate setup; I think he circulates it for quite a while to get a much cleaner product. I talked to a fellow today who owns a burger joint - he has a mercedes diesel, and filters his through an oil filter that looks like an oversized coffee filter (for brewing). Gets them at a local wholesale supply store. Says he pours it through while hot and that's it. Seems a bit *underdone* to me, but he says the car's filter lasts quite a while.
No mods on the truck or the jeep. Stock filters, etc. The filtering I'm doing seems sufficient that I'm getting about the same mileage out of them as normal change intervals. I've been running the Cummins on it for a year (in June), but only one tank so far on the Libby. I'm watching closely, but it seems happy enough on 50% blend (balance #2).

Could you tell more about the WVO blends you use on the CRD? How fine do you filter? Have you modded the Libby with in-line heaters or heated fuel filters?
How cold is it there in WA?
