Chevron Havoline Synthetic Blend Motor Oil 5W-30, available in a 6 Quart Smart Change Box with Deposit Shield Technology, is a premium automotive engine oil. It is formulated with superior base stocks and includes detergent, dispersant, wear control, antioxidant, corrosion inhibitor, and foam suppressant additives. The multigrade oils feature a shear-stable viscosity index improver. The antiwear additives offer outstanding protection for critical engine components. Havoline Motor Oils with Deposit Shield Technology provide a high level of dispersancy to guard against deposits and sludge in stop-and-go driving and during continuous high temperature operation, while also preventing corrosion. Their exceptional high temperature oxidation stability prevents the oil from thickening and gelling in the crankcase, ensuring the PCV systems remain clean for uninterrupted engine performance.
