Using a certified product ensures these sensitive components function correctly. This balance is critical for ensuring instant lubrication during cold starts and protecting components under sustained thermal stress.
The designation indicates a multi-viscosity formulation that flows like a 5-weight oil at low temperatures while maintaining the stability of a 40-weight oil at high operating conditions. At startup, engine parts are metal on metal with no lubrication, creating the highest risk for wear.
