I switched to Mobil 10w-40 over this past winter, but was unable to detect any difference in oil pressure. But my winter driving is generally at temperatures over 40 degrees.
At the rate I'm going, it will take another 11 years to get to the 100,000 mile mark (since the engine overhaul). I'll get back to you then with another update.
