Conversely, in freezing temperatures, multi-grade oils like 10W-30 or 5W-30 are essential because the "W" denotes winter performance, allowing the oil to flow easily at cold startup. While most generic engines follow the standard API (American Petroleum Institute) service classifications, some manufacturers, particularly those with horizontal shafts or torque converters, require specific friction modifier packages.
