The Society of Automotive Engineers (SAE) created the numerical rating system you see on oil containers to describe this resistance to flow. Look for oils specifically marketed as "all-season" or "universal" to handle the fluctuations between summer operation and winter storage without requiring a complete drain and refill twice a year.
