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. API SG/SH,SJ/SL, CCMC G5 and JASO MA2 certified. 10W30, 1 liter, For Case Order 10
