AMSOIL Offers Superior Diesel Protection and Performance
OE15W-40 Synthetic Diesel Oil
Provides excellent protection and performance in both on- and off-road diesel engines for the original equipment manufacturer’s recommended drain interval. Suitable for both modern and older diesel applications requiring API CJ-4 specifications. Exceeds the higher performance demands of modern engines and withstands the stress of heat, soot and acids to help prevent deposits, wear and corrosion.
Premium 5W-40 and 15W-40 API CJ-4 Synthetic Diesel Oil (DEO, DME)
The premium choice for model-year 2007 and newer diesel engines requiring API CJ-4 emissions quality oil standards. Also recommended for pre-2007 diesel engines. Incredibly shear-stable to withstand the stress of heat, soot and acids and help prevent deposits, corrosion and wear. Effectively resists oil consumption and emissions, while improving fuel efficiency Compatible with all exhaust treatment devices, including diesel particulate filters (DPFs). Recommended for three times the OEM drain interval recommendation in diesel applications, not to exceed 50,000 miles/600 hours or one year, whichever comes first.
Series 3000 5W-30 Synthetic Heavy Duty Diesel Oil
Engineered for on- and off-road diesel engines not equipped with diesel particulate filters (DPFs). Delivers extraordinary lubrication for extended drain intervals and withstands the stress of higher heat, higher acid levels and excessive soot-loading found in EGR-equipped engines. Consistently outperforms conventional diesel oils for long-lasting performance and protection.
10W-30/SAE 30 Synthetic Heavy Duty Diesel Oil
Engineered for on- and off-road diesel engines not equipped with diesel particulate filters (DPFs). Exceeds both 10W-30 multi-grade and SAE 30 straight-grade viscosity requirements. Designed to stop viscosity loss and associated bearing and cylinder bore wear over extended drain intervals, while high 12 TBN neutralizes acids from blow-by, exhaust gas recirculation (EGR) and high-sulfur diesel fuels.
15W-40 Synthetic Heavy Duty Diesel & Marine Motor Oil
Engineered for on- and off-road diesel engines not equipped with diesel particulate filters (DPFs). High 12 TBN chemistry neutralizes acids and controls soot thickening from EGR and blow-by to protect against corrosion, cylinder bore polishing (wear) and varnish/sludge deposits. Resists heat and breakdown for long-lasting extended drain performance and protection.
