WHILE SUPPLIES LAST

AMSOIL OE 15W-40 Synthetic Diesel Oil provides excellent protection and performance in both on- and off-road diesel engines for the original equipment manufacturer’s recommended drain interval. It meets API CJ-4 specifications and is suitable for both modern and older diesel applications. AMSOIL OE 15W-40 Synthetic Diesel Oil exceeds the higher performance demands of modern engines and withstands the stress of heat, soot and acids to help prevent deposits, wear and corrosion.

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.

Meets Emission System Requirements
AMSOIL OE 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).

Extreme-Temperature Performance
AMSOIL OE 15W-40 Synthetic Diesel Oil is formulated for improved heat and oxidation resistance over conventional petroleum oil for cleaner engine operation, maintaining power and fuel efficiency for superior engine performance. Its dependable cold-temperature flow assures easier start-up and improved post start-up protection.

Resists Oil Consumption and Emissions
Due to its low rate of volatility (burn-off), AMSOIL OE 15W-40 Synthetic Diesel Oil is able to reduce oil consumption and emissions during operation. It maintains its excellent film strength even during high-temperature operating conditions to ensure dependable protection, performance and fuel efficiency.

Controls Soot-Thickening and Wear
AMSOIL OE 15W-40 Synthetic Diesel Oil is formulated with premium synthetic base stocks and robust detergent/dispersant additives that keep soot particles from agglomerating and forming larger wear-causing particles. The AMSOIL OE 15W-40 Synthetic Diesel Oil formulation allows for optimal soot-related viscosity control to maintain stay-in-grade performance.

AMSOIL OE 15W-40 Synthetic Diesel Oil is recommended for diesel engines and, where appropriate, gasoline engines requiring any of the following specifications:

  • API licensed CJ-4/SN
  • ACEA E9
  • DDC 93K218

COMPATIBILITY
AMSOIL OE 15W-40 Synthetic Diesel Oil is compatible with conventional and synthetic motor oils. Mixing AMSOIL motor oils with other oils, however, will reduce the performance benefits.

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

SERVICE LIFE

I have used this oil since my truck turned 10,000 miles in 2003--regular oil up to that point. (Back then the recommendation was to wait until the engine breaks in). I am only putting a little over 12,000 miles a year on the truck and change the oil & filter once a year. The truck turns 14 years old next month and is still running great!. I would like to think part of this truck's longevity is due to the AMSOIL in the motor.

Unbeleavable product!

By 

from Walnut creek ca

Verified Buyer

Comments about OE 15W-40 Synthetic Diesel Oil:

Use Amsoil in my diesel pickup and blown away at its ability to stay clean for more than 6000 miles. As a retired mechanic I'm familiar with oils and engine maintenance. I've never seen such great performance from any oil. I've been sold on Amsoil for a few years now. Recommend to anyone, all the time. Keep up the great work!

Simply the best!!

By 

from Brandywine WV

Verified Buyer

Comments about OE 15W-40 Synthetic Diesel Oil:

I have used AMSOIL 15W-40 OE oil for well over 20 years, both in my Chevy HD2500 Duramax and my earlier Dodge RAM 2500 Cummings diesel. It has performed superbly. I recently changed injectors at 200k miles and had my fuel rails adjusted. The mechanic said he couldn't believe how clean the engine internals were and how little wear was exhibited. I think I made a convert that day.
