Decoding the SAE 5W-30 Rating The designation "5W-30" is not arbitrary; it is a precise standard that describes the oil's behavior across a wide temperature range. The second number, 30, represents the oil's viscosity at the engine's normal running temperature, ensuring it remains thick enough to maintain a protective film between moving parts under load.
