V-Twin Semi-Synthetic Engine Oil is a synthetic blend multi-grade engine oil formulated to meet the specific demands of large displacement V-Twin engines. It combines the benefits of fully-synthetic oils with the lower cost of petroleum oils. Offers a superior level of protection at high loads and temperatures typical in V-Twin engines. Use in all V-Twin engines where value priced superior protection is desired. Cost-effective all-climate protection. Superior engine protection - Exclusive Bel-Ray anti-wear chemistry reduces bearing and valve train wear and keeps pistons and rings from scuffing. Lower oil consumption - Its flash point is higher than standard petroleum based oils which limits oil burn-off to lower oil consumption and keeps hot engines protected. Increased horsepower - Features high polarity synthetic base oils which provide minimum friction for increased power.
