Fuchs Silkolene Comp 2 Premix is a synthetic ester based 2-Stroke engine oil, with Electrosyntec Technology, for competition off road motorcycles. Comp 2 Premix contains a unique, ash-less, synthetic blend for motocross, enduro and trials machines that require a tank mix oil. It is ideal for use in engines that are used seasonally or infrequently. The Silkolene Comp 2 Premix leaves a coating on all internal surfaces to prevent corrosion. It has an additive system and high ester content which ensures clean burning and freedom from plug fouling, from low speed to full throttle.
