Unlike conventional cars, a hybrid has different demands placed on its engine and motor oil. The frequent stop-and-start cycle and longer periods of inactivity don't allow the engine and oil to reach optimal operating temperature for proper protection. That can lead to increased condensation and fuel dilution, causing corrosion, engine wear, and sludge. It can also hurt a hybrid vehicle's fuel efficiency.  That's why Valvoline formulated a Hybrid Vehicle Full Synthetic Motor Oil. Engineered for the specific needs of hybrids, our exclusive Trap and Lock Technology suspends water molecules in the oil to prevent damage from fuel and water, while ensuring proper lubrication of all metal surfaces. Valvoline Hybrid Vehicle Full Synthetic features an anti-corrosion shield for enhanced protection against rust. Whether your hybrid uses 0W-20 full synthetic or another grade, Valvoline has a full synthetic motor oil to protect your hardworking hybrid. Keep your engine running efficiently mile after mile with Valvoline Full Synthetic Motor Oil.
