Lucas Oil Extreme Duty Marine SAE 20W-50 Engine Oil engine oil made for the toughest requirements marine engines can be exposed to.
The marine oil is made up of the finest paraffinic base oils that exist on the market and has also been strengthened with a unique additive package that has been tested in boat racing. Contains zinc, molybdenum and phosphorus. This provides an extremely durable oil film and provides maximum protection even in the harshest conditions. The Lucas additive package lowers the oil temperature, extends the life of the oil and minimizes metal fatigue in the engine. The base oil and additive package together provide a maximum strength in the oil film between the piston rings and the cylinder wall and reduce oil consumption and increase the oil pressure in worn engines.
