Just noticed that the OP is in Washington state where it really doesn't get very cold in the winter. Average low temps in Dec/Jan/Feb range from 28 - 30 degrees above zero. Average highs temps for the same period range from 38 - 48 degrees.

In comparison - the average low temps in the same months in my home town range from 5 below - 2 degrees above zero. The average highs in those months range from 16 - 24 degrees.

In that moderate climate - you could easily run a 5 or 10WSomething year round with no issues.

Ok, so my standard year round stuff is fine at 10W-30 then. I might put a 5W-30 in it for in the winter just for a little quicker pickup and warm up.
