What is Amsoil SAE 15W-40 Signature Series Diesel Oil?
Amsoil Signature Series SAE 15W-40 Diesel Oil is a premium synthetic diesel oil engineered for superior performance and maximum protection for diesel engines. This oil is designed for use in heavy-duty applications, including on- and off-road trucks, construction equipment, and agricultural machinery.
One of the key benefits of Amsoil Signature Series SAE 15W-40 Diesel Oil is its exceptional wear protection. The oil contains an unprecedented 12 TBN (Total Base Number) level and high levels of detergent and dispersant additives to provide maximum protection against wear, deposit formation, and rust and corrosion. This means that your engine will be better protected against engine wear and can enjoy a longer lifetime.
Another important benefit is its ability to maintain viscosity in high-temperature applications. Amsoil Signature Series SAE 15W-40 Diesel Oil is formulated with Amsoil's advanced synthetic technology to provide superior high-temperature protection and resistance to shearing. This enables the oil to maintain its viscosity, even in the most extreme conditions.
One of the advantages of using Amsoil's Signature Series SAE 15W-40 Diesel oil is that it also delivers extended drain interval capability. This means that it can offer up to triple the original equipment manufacturer's recommended drain interval – while still providing maximum engine protection. This can save you time and money in maintenance, reducing the frequency for oil changes and increasing vehicle availability.
In summary, if you want premium protection for your diesel engine, Amsoil Signature Series SAE 15W-40 Diesel Oil is a wise choice. It provides extreme protection, superior performance, and superior viscosity control, making it ideal for use in demanding diesel applications.
Frequently Asked Questions about amsoil sae 15w-40 signature series diesel oil
MOTOR OIL UNIVERSAL SAE 15W/40 was developed for four-stroke petrol and diesel engines with or without turbos; it can be used in commercial vehicles, work machines or industrial units as well as passenger vehicles, making it the ideal motor oil for a mixed fleet of vehicles.
AMSOIL Signature Series Synthetic Motor Oil provided 75 percent more engine protection against horsepower loss and wear1 than required by the industry standard, extending the life of vital components like pistons and cams. After rigorous third-party testing, the cam lobes show little-to-no wear.
The combined use of AMSOIL motor oil, air and oil filters and engine oil analysis has now made one-fill, zero-waste lubrication a reality. The superior lubricity of AMSOIL products means much less friction, drag and wear on critical engine parts.
Yes, I would recommend this to a friend. I used this oil for my first oil change (2022 F-350 Diesel). The engine starts and runs quieter than with the factory fill. Yes, I would recommend this to a friend.
the Society of Automotive Engineers
SAE, the acronym for the Society of Automotive Engineers, is responsible for establishing a classification system based solely on oil viscosity. To classify the oils, their viscosity is measured in cold conditions at different temperatures below zero, and then in hot conditions at 100ºC.
15W-40 engine oil is commonly used in diesel engines and some gasoline engines. It offers excellent stability, engine protection and high-temperature performance for heavy-duty diesel and high performance engines.
Not only does AMSOIL exceed industry standards and outperform competing brands, it fights viscosity breakdown 46% better than Mobil 1. It's built to stand up to the devastating effects of high-horsepower, modern engines and provide maximum protection.
AMSOIL motor oils are designed to deliver enhanced performance and extended drain intervals, justifying any higher price. AMSOIL offers premium products that rightfully command a premium price. Like anything of real value, however, the true consumer cost doesn't end with the purchase price.
AMSOIL 100% Synthetic Motor Oil
At AMSOIL, we use “100% synthetic” on our product labels.
the Society of Automotive Engineers
SAE International is a professional association and standards development organization for the engineering industry, with a special focus on transport sectors such as automotive, aerospace and commercial vehicles. The organization was originally established as the Society of Automotive Engineers.
Here, SAE represents Society of Automotive Engineers and 40 alludes to the consistency of the oil. In layman's term, we can say 40 is the thickness of the oil. More is the thickness, lesser is the contact between metals, which expands the life of engine motor.
