[Christ]

If you're not burning alot between changes, it's probably the cold weight that's affecting you, and you'll burn a little bit until the engine warms up, characterized by smoking until the engine is warm.

If you're burning more than, say 1.5 or 2qt in 3-5000 miles, you're going to need a thicker warm weight, as well.

IOW - if you're only burning very little, you could still stand to go down a weight in the cold end. If you're burning alot, you'll want a thicker oil. Then again, if you're burning alot, and you intend to keep your vehicle, it's ALWAYS cheaper to fix the problem than to keep buying band-aids for it.
