Overbased Magnesium Sulfonate Detergent
Overbased magnesium sulfonate detergent offers excellent acid neutralization and high-temperature deposit control, making it a preferred alternative or complement to calcium sulfonate in engine oil and marine lubricant formulations. The magnesium sulfonate structure provides superior high-temperature detergency for controlling piston and ring belt deposits in turbocharged diesel engines. It is widely specified in marine two-stroke cylinder oils and aviation piston engine lubricants where magnesium ash is preferred.
