Havoline Energy is an SAE 5W-30 grade motor oil. Will using a motor oil of this viscosity damage my engine?
Vehicle manufactures recommend lubricants by both their viscosity and performance classifications, not just by viscosity alone. They are primarily concerned with the performance of an oil and its ability to prevent wear, to keep the engine clean and free of deposits, and to resist thickening in service. Havoline Energy is formulated in a viscosity grade which provides fuel consumption savings, but it also meets and exceeds the highest published manufacturer and industry performance specifications, including the benchmark API SL category.
