Drivers who frequently operate in stop-and-go traffic or subject their engines to heavy loads may benefit from these specialized oils earlier than the factory schedule suggests. The robust nature of these thicker lubricants creates a stronger hydrodynamic layer between moving parts, which can mask the effects of wear and reduce noise common in aged engines.
