Application
K-31 is a high molecular weight calcium sulfonate lubricating oil additive. It is generally used with acid neutralizing and inhibitor additives in engine oils. This additive provides excellent detergency for upper ring belt deposit control under the high operating temperatures encountered in supercharged diesel engines. It also provides excellent rust control.
