Electrosyntec uses electrostatic forces to bond low friction molecules to stressed metal surfaces, releasing hidden power and ensuring long-term performance retention and exceptional stay-in-grade characteristics even under race conditions. Ideal for all highly tuned, high output engine transmission units. Race proven to provide exceptional anti-wear and anti-friction performance under all extremes of temperature.

PRO 4 15W-50 is ideal for larger capacity engines (750cc and above) especially in hot conditions. Always consult engine manufacturers handbook for SAE grade recommendations.
