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.

GREAT oil but comes with a price

By 

from Ohio

Verified Buyer

    Comments about OE 15W-40 Synthetic Diesel Oil:

    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.

    Comments about OE 15W-40 Synthetic Diesel Oil:

    Well, in my experience with the OE 15W-40 diesel oil can't be beat. The very first time I used it about 5 yrs. Ago I had just taken a 900 mile trip got 20.1 miles to the gallon. Switched to Amsoil 15w-40 and did the very same trip got one mile to the gallon better fuel economy. My engine will even start in extreme cold using this oil and never be at a loss for pressure.

    I would like to refer, instead, to your marine engine oil

    By 

    from Perth. ON CANADA

    Verified Buyer

    Comments about OE 15W-40 Synthetic Diesel Oil:

    I have used this product for one season and will be using it again for the next season. Mercruiser recommends 25 - 40 oil - the synthetic oil that I am currently using from your line of products is 10 - 40. I realize that you are now marketing a synthetic blend 15 - 40 for marine engines. Given that I prefer the full synthetic oil, when will AMSOIL begin marketing a 25 - 4- full synthetic marine oil

    • 3 Cadillacs, 1 Ford F-250, 2 Mercruiser

    Verified Buyer

    Comments about OE 10W-30 Synthetic Diesel Oil:

    I never gave much thought to how much one brand of oil could differ from another of equal weight. My 6.0l diesel ran quieter, smoother and I dare say more efficient. I'm hooked.
