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.

  • High-zinc formula guards against wear
  • Ideal for flat-tappet cams
  • Resists deposits to help keep engines clean
  • Convenience of use for gas and diesel engines

Excellent Wear Protection

Premium Protection Synthetic Motor Oil is high-viscosity oil engineered to protect against metal-to-metal contact. It resists viscosity loss due to shear and is formulated with a heavy treatment of zinc and other anti-wear additives for excellent protection of gears, bearings, cam lobes and other high-pressure components in engines and transmissions. Premium Protection Synthetic Motor Oil helps extend equipment life.

Wet Clutch Compatible

Premium Protection Synthetic Motor Oil contains no friction modifiers, making it ideal for motorcycles, maintenance equipment and other wet-clutch transmission applications. Formulated to prevent clutch glazing and slippage, it helps ensure smooth clutch engagement and long-term, dependable transmission operation. Premium Protection Synthetic Motor Oil reduces clutch wear for extended transmission life.

Hi Temperature Protection and Oxygen Breakdown

Premium Protection Synthetic Motor Oil is formulated to overcome the thermal deficiencies common to conventional petroleum oils. Volatilization (burn-off), oxidation and excessive deposit formation from high heat are greatly reduced. Viscosity thickening is controlled and engines run cleaner, promoting cooler operation and long engine life in air- or liquid-cooled engines. In addition, the higher viscosity of AMSOIL 20W-50 Synthetic Motor Oil may help reduce motor oil consumption in equipment that experiences higher-than-normal usage rates when lower-viscosity lubricants are installed.

Increases Time Between Oil Changes in Diesel and Gasoline Engines

Superior synthetic base oil and additive technology exceeds the requirements of both gasoline and diesel engines. Premium Protection Motor Oil is designed to neutralize acids, disperse soot and last longer in service than conventional oils.

Applications

DME Meets Emission System Requirements

Amsoil 15W-40 Synthetic Diesel Oil is a low-sulfated ash formulation that meets the requirements for low-emission quality diesel oil and protects under the most severe conditions found in modern diesel engines. It is compatible with all exhaust treatment devices and is designed for engines equipped with diesel particulate filters (DPF).

Longer Drain Intervals

Amsoil Premium 15W-40 Synthetic Diesel Oil can extend drain intervals far beyond those recommended for conventional petroleum oils. Its unique synthetic formulation and long-drain additive system (10.4 TBN) deliver superior engine protection, cleanliness and performance over extended drain intervals. Amsoil 15W-40 Synthetic Diesel Oil provides maximum protection for up to 3X the OEM-recommended drain interval, even further with oil analysis.

Minimizes Oil Consumption and Emissions

Amsoil 15W-40 Synthetic Diesel Oil has lower volatility (burn-off) than conventional petroleum oils, resulting in less oil vapor passing into the combustion chamber, lowering oil consumption and emissions. Lower volatility helps Amsoil Premium Synthetic Diesel Oil retain its viscosity after high-temperature service for continued dependable protection.

Controls Soot-Thickening and Wear

The advanced synthetic base oils in Amsoil 15W-40 Synthetic Diesel Oil are naturally resistant to soot contamination and oxidative thickening. That, along with a heavy fortification of detergent/dispersant additives, keeps soot particles suspended independently, helping prevent the formation of larger, wear-causing particles. Viscosity increase is minimized and soot-related wear is controlled.

Perfect Setup for Fleets

Amsoil Premium 15W-40 Diesel Oil reduces operating costs through extended drain intervals. It is engineered for a wide range of applications, allowing fleet operators to consolidate engine oil inventories in mixed fleets. In addition, it reduces downtime through extended drain intervals and improved equipment protection.

PRODUCT 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 the industry’s premier synthetic technology with AMSOIL premium additives, AMSOIL 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. AMSOIL Series 3000 5W-30 Synthetic Heavy Duty Diesel Oil consistently outperforms conventional and synthetic diesel oils for long-lasting performance and protection.

Engine Wear Maximum Protection

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

Increases Fuel Economy

AMSOIL 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.

Longer Periods Between Oil Changes

AMSOIL 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.

Decreases Wear and Soot-Thickening Deposits

AMSOIL 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

AMSOIL 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 AMSOIL Series 3000 Diesel Oil retain its viscosity after high-temperature service for continued dependable protection and excellent fuel economy.

Excellent Performance in High Temperatures

AMSOIL 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 -50°C (-58°F) for improved cold-temperature oil flow, reduced bearing wear and easier starting.

APPLICATIONS

AMSOIL Series 3000 5W-30 Synthetic Heavy Duty Diesel Oil is recommended for diesel engines, including those that are trubocharged, gasoline engines and other applications that require any of the following specifications:

  • API CI-4+, CI-4, CH-4, CF-2, CF, SL, SJ
