Valvoline Hybrid Vehicle Full Synthetic 0W-20 is engineered for Hybrid Engines. Unlike traditional vehicles, a hybrid vehicle has unique demands placed on the engine and oil due to its frequent stop-start cycle. This can cause lower average operating temperatures, increased condensation/water and fuel dilution and engine corrosion, added wear, and sludge. Valvoline Hybrid Vehicle Engine Oil is formulated with exclusive Trap & Lock Technology to suspend water molecules in the oil to prevent damage from fuel and water. Anti-Corrosion Shield offers enhanced protection and ensures proper lubrication of all metal surfaces.
