Amsoil Heavy-Duty Synthetic Diesel Oil is formulated for hard-working equipment. It is engineered to provide 4X better wear protection than required by the Detroit Diesel DD13 Scuffing Test for Specification DFS 93K222, giving you the edge to keep trucks and equipment operating at peak performance. Amsoil Heavy Duty Synthetic Diesel and Gasoline oil is for use in both diesel and gasoline engines. Ideal for applications where the extra protection of a higher-viscosity oil is desired. The higher viscosity may help reduce motor oil consumption in equipment experiencing higher than normal oil usage rates while running lower viscosity lubricants.
AMSOIL Series 3000 5W-30 Synthetic Heavy Duty Diesel Oil delivers extraordinary lubrication in both diesel and gasoline engines found in commercial, fleet and personal vehicles. By combining synthetic base oils with AMSOIL premium additives, Series 3000 exceeds the higher performance demands of modern engines, including those with turbochargers. It withstands the stress of higher heat, higher acid levels and excessive soot-loading found in exhaust gas recirculation (EGR)-equipped engines. Series 3000 5W-30 Synthetic Heavy Duty Diesel Oil consistently outperforms conventional and synthetic diesel oils for long-lasting performance and protection.
