These are not arbitrary ratings but precise measurements of the fluid's behavior in different temperatures. The number preceding the 'W' indicates the cold-weather performance; a lower number means the oil remains fluid and pumpable in freezing conditions, ensuring protection immediately after startup.
Synthetic Blend: As the name suggests, this is a mixture of mineral oil and synthetic base stocks. The primary categories are mineral, synthetic blend, and full synthetic.
