The appropriate lubricant for a Nissan Altima engine is a critical factor influencing its performance and longevity. Engine oil serves the primary function of reducing friction between moving parts, dissipating heat, and removing contaminants produced during combustion.
Utilizing the correct oil type as specified by the manufacturer maximizes fuel efficiency, minimizes wear and tear on engine components, and contributes to optimal engine operating temperatures. Consistent adherence to recommended oil change intervals, coupled with the use of the correct oil viscosity, ensures the ongoing health and reliable operation of the vehicle’s powertrain.
