AMSOIL Synthetic
10W-30/SAE 30 Heavy-Duty Diesel Oil

Its 12 TBN Offers Outstanding Wear Protection

AMSOIL Synthetic 10W-30/SAE 30 Heavy-Duty Diesel Oil is a super heavy-duty diesel lubricant designed for use in commercial and industrial applications and is recommended for virtually every diesel application that specifies this viscosity. It contains premium additives with a high 12 TBN to neutralize acids from blow-by, exhaust gas recirculation (EGR) and high-sulfur diesel fuels. It protects against damaging piston deposits, ring sticking and sludge. In every engine tested (including Detroit Diesel, Caterpillar, Cummins and Mack), the advanced 12 TBN additive system of AMSOIL 10W-30/SAE 30 Heavy-Duty Diesel Oil significantly reduced ring wear, ring breakage, cylinder bore polishing, cylinder lining wear, piston deposits and oil consumption.

Retains Its Viscosity

AMSOIL Synthetic 10W-30/SAE 30 Heavy-Duty Diesel Oil loses only 6.3% of its mass to high-temperature volatility (conventional oils often lose over 15%), which reduces oil consumption and hydrocarbon emissions. It also allows the oil to retain its original viscosity after high-temperature service for continued dependable protection, fuel economy, peak engine performance and extended drain intervals.

Prevents Rust

AMSOIL Synthetic 10W-30/SAE 30 Heavy-Duty Diesel Oil's special rust-inhibiting additives reduce rust, which makes it ideal for equipment stored long term.

Extended Service Life

AMSOIL Synthetic 10W-30/SAE 30 Heavy-Duty Diesel Oil is a proven long-drain oil and can extend drain intervals far beyond those recommended for conventional oils. Its unique synthetic formulation and long-drain additive system deliver the best possible engine protection, cleanliness and performance over extended drain intervals, reducing vehicle maintenance and waste oil disposal costs.

AMSOIL Synthetic Heavy Duty Diesel Oil is recommended for extended drain intervals in unmodified, mechanically sound vehicles or equipment as follows:

Personal light truck vehicles with diesel engines:

Normal Service: Up to 25,000 miles or one year, whichever comes first, or longer based on oil analysis.

Severe Service: Up to 15,000 miles or one year, whichever comes first, or longer based on oil analysis.

Commercial or fleet vehicles, long-haul trucks, marine craft, RV/motor homes and off-road equipment with diesel engines:

Non-EGR equipped diesels: Up to two times the OEM (original equipment manufacturer) recommended drain interval or one year, whichever comes first, or longer based on oil analysis.

EGR equipped or low emission diesels: Extend drain intervals based on oil analysis or use the longest drain recommendation of the OEM (original equipment manufacturer).

Personal vehicles with gasoline engines:

Up to two times the OEM (original equipment manufacturers) recommended drain interval (not to exceed 15,000 miles without oil analysis) or one year, whichever comes first.

Oil Filter Service Intervals

Extended oil drain intervals are based on the user following AMSOIL recommended oil filter service intervals:

Personal light truck vehicles with diesel or gasoline engines:

If using an AMSOIL Ea™ Oil Filter, install a new oil filter at time of oil change. AMSOIL Ea™ Oil Filters offer a 25,000-mile or one-year service life, whichever comes first.

If using other brands of oil filters, install a new oil filter at time of oil change then change at the engine manufacturer's recommended filter change intervals.

Commercial, fleet, marine and RVs/motor homes with diesel engines:

If using an AMSOIL Ea™ Oil Filter, install a new oil filter at time of oil change then change at 2X (two times) the OEM standard interval, not to exceed 60,000 miles in long-haul trucks.

If using other brands of oil filters, install a new oil filter at time of oil change then change at the engine manufacturer's recommended filter change intervals.

Note: AMSOIL Ea™ Oil Filters are designed for extended drain intervals. They stop smaller particles, allow more oil flow and last longer than regular filters.

Applications

Where these viscosity grades are specified, AMSOIL Synthetic 10W-30/SAE 30 Heavy-Duty Diesel Oil provides outstanding performance as a straight-grade SAE 30 for older two- and four-stroke diesels and as a multi-grade SAE 10W-30 in modern four-stroke diesels as well as gasoline engines. AMSOIL 10W-30/SAE 30 Heavy-Duty Diesel Oil is ideal for use in a wide variety of light- and heavy-duty applications, including those under warranty, such as agriculture, off-road construction, trucking, mining, industrial (pumps and generators) and personal automotive or commercial transportation. It is recommended for use with low- or high-sulfur diesel fuels in standard, turbocharged or supercharged engines, including modern low-emission diesels such as those equipped with EGR systems. AMSOIL 10W-30/SAE 30 Heavy-Duty Diesel Oil is recommended for applications requiring the worldwide performance specifications listed on the AMSOIL Corporate website (see "Engine Protection Requirements" below).

Engine Protection Requirements

AMSOIL Synthetic Motor Oils meet or exceed specific API, ACEA and ILSAC service classifications and the engine protection requirements of various domestic and foreign engine manufacturers. Please visit the AMSOIL Corporate website for an up-to-date listing on this product.
