Superantigel is a depressant additive for reducing the maximum filterability and solidification temperature of diesel fuel. Prevents the formation of ice plugs, protects filters from clogging with paraffins even after long periods of inactivity in the cold, and lubricates fuel equipment. Superantigel is most effective when introduced into the fuel before it becomes cloudy. The additive is recommended for continuous use in all types of diesel engines in the cold season.
