SAE 15W-40 Synthetic Heavy Duty Diesel & Marine Motor Oil Data Bulletin

Description

AMSOIL Synthetic Heavy Duty Diesel & Marine Motor Oil is a premium diesel oil that provides excellent performance in all types of diesel engines where highly effective control of wear and deposits is vital. Engineered with heavy-duty dispersant/detergent additives, its Total Base Number (TBN) of 12 neutralizes acids and controls soot thickening from exhaust gas recirculation (EGR) and blow-by to protect against corrosion, cylinder bore polishing (wear), varnish and sludge deposits. AMSOIL 15W-40 Diesel Oil resists heat and breakdown better than conventional petroleum oils for long-lasting performance and protection.

AMSOIL, the leader in automotive synthetic lubrication, produced the world’s first API qualified synthetic motor oil in 1972. Trust the extensive experience of AMSOIL The First in Synthetics® to do the best job protecting your engine.

Extends Drain Intervals

AMSOIL Synthetic Heavy Duty Diesel & Marine Motor Oil can extend drain intervals far beyond those recommended for conventional petroleum oils. Its unique synthetic formulation and long-drain additive chemistry deliver maximum engine protection, cleanliness and performance over extended drain intervals, reducing vehicle maintenance and waste-oil disposal costs.

Controls Soot and Wear

AMSOIL Synthetic Heavy Duty Diesel & Marine Motor Oil is heavily fortified with detergent/dispersant additives and is naturally resistant to soot. It is designed to keep soot particles suspended independently and prevent them from aggregating to form larger, wear-causing particles. Viscosity increase is minimized and soot-related wear is reduced.

Reduces Oil Consumption and Emissions

AMSOIL Synthetic Heavy Duty Diesel & Marine Motor Oil has lower volatility than conventional petroleum oils. Oil consumption and emissions are minimized due to less vapor passing into the combustion chamber. Lower volatility helps AMSOIL 15W-40 Diesel Oil retain its viscosity after high-temperature service for continued dependable protection.

Excellent Cold-Flow Properties

AMSOIL Synthetic Heavy Duty Diesel & Marine Motor Oil eases cold-weather starting (down to -44°F) and provides vital startup lubrication to help prevent engine wear. AMSOIL Synthetic Heavy Duty Diesel Oil outperforms conventional 15W-40 petroleum oils and minimizes the impact of cold-weather operation.

COMPATIBILITY

AMSOIL Synthetic Heavy Duty Diesel & Marine Oil is compatible with conventional and synthetic motor oils. Mixing AMSOIL motor oils with other oil, however, will shorten the oil’s life expectancy and reduce the performance benefits.

AMSOIL does not support extended drain intervals where oils have been mixed.

Aftermarket oil additives are not recommended for use with AMSOIL motor oils.

Series 3000 5W-30 Synthetic Heavy Duty Diesel Oil Data Bulletin

Description

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.

Maximum Protection Against Engine Wear

Even under high temperatures and pressures, Series 3000 Diesel Oil’s superior film strength and anti-wear additives help prevent metal-to-metal contact. Series 3000 reduces ring wear, cylinder bore polishing, oil consumption and valvetrain wear for improved engine life and lower maintenance costs.

Maximizes Fuel Economy

Series 3000 Diesel Oil is energy efficient for reduced fuel costs. Its low viscosity minimizes “drag” associated with high-viscosity oils, allowing the engine to operate more freely, maximizing power and fuel economy.

Extends Drain Intervals

Series 3000 Diesel Oil can extend drain intervals far beyond those recommended for conventional oils. Its unique synthetic formulation and long-drain additive system deliver maximum engine protection, cleanliness and performance over extended drain intervals, reducing vehicle maintenance and waste oil disposal costs.

Controls Soot-Thickening and Wear

Series 3000 Diesel Oil is heavily fortified with detergent/dispersant additives and is naturally resistant to soot. It is designed to keep soot particles suspended independently and prevent them from attaching together to form larger, wear-causing particles. Viscosity increase is minimized and soot-related wear is controlled.

Reduces Oil Consumption and Emissions

Series 3000 Diesel Oil effectively reduces high-temperature volatility (evaporation), outperforming conventional oils. Because less oil vapor passes into the combustion chamber, oil consumption and emissions are reduced. Additionally, lower volatility helps Series 3000 Diesel Oil retain its viscosity after high-temperature service for continued dependable protection and excellent fuel economy.

Excels in Extreme Temperatures

Series 3000 Diesel Oil resists thermal (heat) breakdown, oxidation and sludge formation better than conventional oils. And unlike conventional petroleum oils, AMSOIL Series 3000 contains no wax. It stays fluid down to -47°C (-53°F) for improved cold-temperature oil flow, reduced bearing wear and easier starting.

COMPATIBILITY

AMSOIL Series 3000 5W-30 Synthetic Heavy Duty Diesel Oil is compatible with other conventional and synthetic motor oils. Mixing AMSOIL motor oils with other oils, however, will shorten the oil’s life expectancy and reduce the performance benefits. AMSOIL does not support extended drain intervals where oils have been mixed.

Aftermarket oil additives are not recommended for use with AMSOIL motor oils.
