As a result, I'm not concerned with the wear protection difference between
multi and straight-weight oil. I am, however, concerned about the lack of
lubrication caused by the sudden temperature swings we get in Iowa.

Multi-viscosity takes care of that problem.

My rationale exactly. Two days ago, we broke a record here with a high of 79
degrees. They say it *may* get up to 40 this Saturday.
