AMSOIL Diesel Oil is engineered to deliver exceptional protection, performance, and reliability for both light-duty and heavy-duty diesel engines. Whether you're managing a fleet, driving a turbo diesel pickup, or operating off-road equipment, AMSOIL provides the durability needed to keep engines running strong in the most demanding conditions.

One of the standout benefits of AMSOIL Diesel Oil is its ability to combat wear and reduce oil consumption. Its advanced synthetic formulation provides a strong lubricating film that protects engine components from metal-to-metal contact, especially under high load and extreme heat. This extends engine life and enhances performance over time.

AMSOIL’s diesel oils also offer outstanding soot and deposit control. The oil’s superior detergency keeps engines clean by minimizing harmful buildup, which helps maintain fuel efficiency and optimal engine performance. It also prevents sludge and varnish that can clog components and reduce engine reliability.

For cold-weather protection and excellent startup performance, AMSOIL 5W40 is a popular choice among diesel owners. It delivers fast oil flow in low temperatures and resists thermal breakdown in extreme heat. For those needing a more traditional option, AMSOIL 15W40 offers excellent all-around performance, making it ideal for mixed fleets and older diesel engines.

Another key advantage is the extended drain capabilities. These oils are formulated to resist oxidation and degradation, allowing for longer intervals between oil changes—saving both time and maintenance costs.

To get the right diesel oil for your specific engine, finding an AMSOIL dealer near me ensures you’ll receive expert guidance and access to a full product line.

In summary, this diesel oil offers top-tier protection, cleaner engine performance, and long-lasting reliability—perfect for diesel engines that work as hard as you do.
