Using electrostatic forces to bond low-friction molecules to stressed metal surfaces, Pro 4 releases hidden power and ensures long-term performance retention; exceptional stay-in-grade characteristics makes it ideal for all highly tuned, high-output engine transmission units. Fully synthetic and race-proven to provide exceptional anti-wear and anti-friction performance under all temperature extremes. Utilizes ester synthetics, derived from aerospace lubrication technology, to impart excellent anti-wear properties throughout a wide operating temperature range. Advanced surface chemistry provides vital protection to pistons and bores, cam lobes and bearings, even during the cold start period before full lubricant flow is achieved.
