Engine friction represents a critical challenge in automotive engineering, directly impacting vehicle performance, fuel efficiency, and long-term mechanical reliability. By implementing strategic lubrication techniques, advanced oil technologies, and precision engineering approaches, vehicle owners and mechanics can significantly minimize friction-related wear, reduce energy losses, and enhance overall engine functionality across diverse operating conditions.
What Causes Engine Friction?
Engine friction emerges from multiple mechanical interactions between moving components, including:
