Ultra1Plus SAE 20W-50 Full Synthetic V-Twin 4T Engine Oil, 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 Read more Highlights: Exceptional thermal stability to help resist oxidation and high-temperature degradation. Resists viscosity breakdown. Helps maximize power and acceleration. Prevent against ring sticking and build-up of harmful deposits. Provide outstanding wet clutch protection.
