Custom-Blended For Outstanding Performance in Today's Engines

PRODUCT DESCRIPTION

AMSOIL Synthetic Heavy-Duty Diesel and Marine Motor Oil combines the superior lubricity and performance capabilities of a premium synthetic lubricant with special rust and corrosion inhibitors. AMSOIL Synthetic Heavy-Duty Diesel and Marine Motor Oil is recommended for engines used in marine applications, as well as diesel engines used in trucks, fleets, mining, earth moving, construction and farm equipment. Other applications include taxi and local delivery fleets with gasoline or diesel engines. With its extended drain intervals, AMSOIL Synthetic Heavy-Duty Diesel and Marine Motor Oil reduces maintenance costs, downtime and the cost of waste oil disposal.

Provides High Shear Stability

AMSOIL Synthetic Heavy-Duty Diesel and Marine Motor Oil surpasses the European ACEA and North American SAE oil specifications for high temperature/high shear (HTHS) viscosity. It is significantly more shear stable than conventional motor oils, retaining its viscosity at temperatures and loads that break down conventional oils. AMSOIL Synthetic Heavy-Duty Diesel and Marine Motor Oil maintains an extremely protective viscosity of greater than 3.7 cP at 302F (150C) in the ASTM D-4683 High Temperature/High Shear Test, exceeding the test limits.

Prevents Rust and Corrosion

AMSOIL Synthetic Heavy-Duty Diesel and Marine Motor Oil contains special rust and corrosion-inhibiting additives to prevent the rusting or corrosion of iron, copper, lead and aluminum materials.

Improves Fuel Economy

The premium quality synthetic base stocks in AMSOIL Synthetic Heavy-Duty Diesel and Marine Motor Oil provide a tough lubricating film on all engine parts, reducing friction and fuel consumption. Reduced fuel consumption reduces exhaust emissions of carbon dioxide, water and particulates.

Resists Oxidation - Reduces Engine Wear

Conventional oils oxidize at high temperatures, causing sludge and deposit build-up that decrease fuel efficiency and contribute to corrosion and increased engine wear. AMSOIL Synthetic Heavy-Duty Diesel and Marine Motor Oil, with a flash point of 442F (228C), resists oxidation and thermal breakdown far better than conventional oils. It continues to provide maximum protection at tempera-tures that oxidize conventional oils. Also, the advanced heat transfer capabilities and high lubricity of AMSOIL Synthetic Heavy-Duty Diesel and Marine Motor Oil helps engines run cooler and reduces wear.

Extended Drain Intervals

AMSOIL Synthetic Heavy-Duty Diesel and Marine Motor Oil is formulated for extended drain intervals. Its unique synthetic formulation, improved detergent/dispersant capabilities, and long drain additive package ensure maximum engine protection, cleanliness and performance over extended drain periods. Its advanced 12 TBN formulation keeps engines in superb condition even when the oil is used for extended drain intervals.

Provides Low Temperature Protection

AMSOIL Synthetic Heavy-Duty Diesel and Marine Motor Oil remains fluid at temperatures as low as -47F (-44C). It circulates rapidly to provide vital lubrication and prevent engine wear caused by lack of oil flow. AMSOIL Synthetic Heavy-Duty Diesel and Marine Motor Oil allows quicker, easier cold temperature starting with less engine wear.

Reduces Oil Consumption and Emissions

AMSOIL Synthetic Heavy-Duty Diesel and Marine Motor Oil passes the NOACK Volatility Test. Many conventional lubricants cannot pass this requirement. Low volatility means less oil vapor passing into the combustion chamber. A reduction of oil vapor means lower oil consumption and lower exhaust emissions. The high detergent alkalinity of AMSOIL Synthetic Heavy-Duty Diesel and Marine Motor Oil also helps reduce oil consumption.

MIXING AMSOIL

AMSOIL Synthetic Heavy-Duty Diesel and Marine Motor Oil is compatible with conventional petroleum oils and other synthetic oils; however, mixing AMSOIL Synthetic Heavy-Duty Diesel and Marine Motor Oil with a conventional oil will shorten the extended drain period of AMSOIL Synthetic Heavy-Duty Diesel and Marine Motor Oil. Engine oil additives or after-market products are not recommended for use with AMSOIL Synthetic Heavy-Duty Diesel and Marine Motor Oil.

NEW VEHICLE UNDER WARRANTY

The use of AMSOIL Synthetic Synthetic Heavy-Duty Diesel and Marine Motor Oil will not void new vehicle warranties. New vehicle warranties are based on the use of oils meeting specific API service classifications and SAE viscosity grades. AMSOIL Synthetic Heavy-Duty Diesel and Marine Motor Oil meets the current API and SAE requirements and is perfectly suited for use in any new vehicle stipulating those requirements in its owner's manual.

SERVICE LIFE

Diesel engines, fleet vehicle engines and industrial engines: drain oil at intervals up to two times longer than recommended by the engine manufacturer or at six month intervals. Extended drain intervals may be used if they are supported by the findings of used oil analysis.

Personal car and light-truck non-turbocharged gasoline engines and marine craft gasoline engines: drain oil at intervals up to three times longer than those recom-mended by the engine manufacturer, or one year, whichever comes first.

Non-commercial, turbocharged passenger car gasoline engines: drain oil at intervals up to two times longer than those recommended by the engine manufacturer, or six months, whichever comes first.

High-performance or racing engines: drain oil at intervals determined by the findings of a used oil analysis program.

Motorcycle engines and small four-cycle gasoline engines: use engine manufacturer's oil drain recommendations.

Change AMSOIL Full Flow Oil Filters at 12,500-mile or six-month intervals, whichever comes first, in gasoline engines. In diesel engines change AMSOIL Full-Flow Oil Filter at 7,000 miles or six months, whichever comes first. Change other manufacturers' oil filters at the engine manufacturer's recommended filter change intervals.
