Lucas Extreme Duty Marine Semi-Synthetic 20W-50 Engine Oil is designed for high-performance boats requiring maximum protection. It is fortified with high levels of zinc, molybdenum, and phosphorus, creating a tougher, thicker additive film to withstand severe conditions. This oil lowers temperatures, extends oil life, minimizes metal fatigue, and improves film strength between the cylinder wall and piston rings.
