AMSOIL Premium Full Synthetic 15w40 Diesel Engine Oil – API CJ-4

Meets Emission System Requirements, Extends the Life of Diesel Particulate Filters

AMSOIL Premium Full Synthetic 15w40 Diesel Engine 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).

Controls Soot Thickening and Wear

The advanced synthetic base oils in AMSOIL Premium 15w40 Diesel Engine Oil are naturally resistant to soot contamination. 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 diesel engine wear is controlled.

Reduces Oil Consumption and Emissions

AMSOIL Premium Synthetic 15w40 Diesel Engine Oil has lower volatility (burn-off) than conventional petroleum oils. Because less oil vapor passes into the combustion chamber, oil consumption and emissions are reduced. Additionally, lower volatility helps AMSOIL Premium 15w40 Diesel Oil retain its viscosity after high-temperature service for continued dependable protection.

Ideal for Fleets

AMSOIL Premium Synthetic 15w40 Diesel Engine Oil is engineered for a wide range of applications, allowing fleet operators to consolidate engine oil inventories in mixed fleets. In addition, it reduces operating costs and downtime through extended oil change intervals and improved equipment protection.

An AMSOIL 15w40 Diesel Oil Change Costs Less Per Mile than a Conventional Diesel Oil Change

Extended Oil Change Intervals

AMSOIL Premium 15w40 Diesel Engine Oil can extend oil change intervals far beyond those recommended for conventional petroleum oils. Its unique full synthetic formulation and long-drain additive system (10.4 TBN) deliver superior engine protection, cleanliness and performance over extended oil change intervals. AMSOIL Premium 15w40 Diesel Oil provides maximum protection for up to three times the OEM-recommended oil change interval, even further with oil analysis. It is recommended for extended oil change intervals in engines that are unmodified and in good operating condition.

Diesel Engine Service: Three times (3X) OEM* recommendation, not to exceed 50,000 miles/600 hours or one year, whichever comes first, with the following exceptions. Drain intervals may be extended further with oil analysis.

• 2007 – 2009 Caterpillar C13 and C15 on-highway engines must follow OEM drain interval
• 2007 – Present Dodge, Ford and GM light-duty diesel pickups must follow OEM-recommended drain interval. Drain intervals may be extended with oil analysis.

Gasoline Engine Service: Two times (2X) OEM* recommendation, not to exceed 15,000 miles or one year, whichever comes first.

*Original Equipment Manufacturer. Operating conditions and drain intervals for normal and severe service are defined by the OEM. Refer to your owner’s manual.

Note: Extended oil drain intervals are not recommended when using biofuels containing >10% ethanol or 10% biodiesel (B10). Follow OEM drain intervals or extend drain intervals with oil analysis.

Oil Filter Service Intervals

Extended oil change intervals are based on the user following AMSOIL recommended oil filter service intervals. Install a new oil filter at time of oil change.

• AMSOIL Ea Oil Filters and Donaldson Endurance Oil Filters are full flow oil filters designed for extended oil drain intervals. They stop smaller particles, have less restriction and last longer than regular oil filters. For best performance, use AMSOIL Ea or Donaldson Endurance oil filters. If using other brands of oil filters, install a new oil filter at time of oil change then change at the OEM’s (original engine manufacturer) recommended filter change intervals.
• For maximum engine and oil life, AMSOIL Ea Bypass Oil Filters are specialized for the removal of small, wear-causing dirt particles. These filters are placed outside the main line of oil circulation, using an AMSOIL Bypass Oil Filtration System mount.

Good to Know

• For best results, use AMSOIL Engine and Transmission Flush before installing AMSOIL synthetic motor oil.
• For maximum engine protection, use an AMSOIL Ea Extended Life Oil Filter.
• AMSOIL recommends checking the oil at a minimum of every 3,000 miles to maintain proper fill levels and maximum engine protection.
• Oil Analyzers, Inc., a division of AMSOIL, Inc., provides cost effective, quality oil analysis services.
• Most quick lube service centers will install these products upon request or you can install them yourself.
