The lubricant specified for use in the Toyota Highlander is a critical component for engine performance and longevity. Selecting the correct type and viscosity ensures optimal operation and minimizes potential engine wear. Using the manufacturer’s recommended fluid is essential to maintaining warranty compliance and preserving the vehicle’s operational integrity.
Proper lubrication within the engine reduces friction between moving parts, which in turn minimizes heat generation and component degradation. This contributes to increased fuel efficiency and a prolonged engine lifespan. Furthermore, using the appropriate grade and specification helps to maintain a clean engine environment by suspending and removing contaminants. Consistent adherence to recommended service intervals and the use of high-quality fluids are vital for maximizing engine protection.
