U1P-Ride SAE 20W-50 Synthetic 4T Engine Oil, V-Twin, API SJ, JASO MA2 U1P-Ride SAE 20W-50 Full Synthetic 4T Engine Oil, V-Twin, API SJ, JASO MA2 This product is a super high-performance, full synthetic, 4-stroke engine oil designed for outstanding performance in high-temperature, high-load, atmospheric, turbo or supercharged V-Twin engines. This oil is fortified with a complex additive system to provide excellent frictional properties for optimized wet-clutch performance. A myriad of anti-oxidant compounds provide synergistic anti-oxidant properties for outstanding thermal stability. Highly shear stable polymers protect from viscosity excellent wear protection at high-speed and high temperature conditions. This oil is recommended for V-Twin Engines which specify the use of 4T engine oil with JASO MA2 and/or API SJ performance. Exceeds performance requirements: API SJ JASO MA2 EXCEPTIONAL WEAR PROTECTION Helps to extend engine life. DISPERSANT CAPABILITY Works by keeping deposits suspended in the oil so they do not form harmful sludge or varnish. EFFECTIVE PROTECTION FROM RUST AND CORROSION Helps to prevent the oil from breaking down and forming acids, which can corrode metal surfaces. EXCELLENT DETERGENT Helps to keep the engine clean by breaking down and removing deposits. LONGER OIL LIFE Oil drain interval has lower volatility and better oxidation stability. ANTI-FRICTION FORMULATION Keeps engines running cool by effectively reducing friction and heat.
