Choosing the Right Diesel Oil
Choosing the Right Diesel Oil
The introduction of AMSOIL Signature Series Max-Duty Synthetic Diesel Oil and Heavy-Duty Synthetic Diesel Oil brings even greater protection and performance, as well as additional viscosity options. How can you decide which oil is right for you?
Signature Series 5W-30 (DHD)
- Newer Over-the-Road Trucks
- Mixed Fleets
Signature Series 5W-30 is a versatile oil aimed at mixed fleets of diesel and gasoline vehicles, simplifying maintenance and lubricant inventory. Its extended-drain capability further maximizes convenience and minimizes downtime for fleet managers with busy schedules.
It is also an outstanding option for newer over-the-road trucks that come factory-filled with 10W-30 for improved fuel economy.
- 6X more engine protection*
- Recommended for both diesel and gasoline vehicles, simplifying maintenance and lubricant inventory
- Excellent fuel economy
- Outstanding cold-temperature performance
- Extra protection for extended drain intervals
Heavy-Duty 10W-30 (ADN)
- Newer Over-the-Road Trucks
- Smaller Off-Road Equipment
- Some Turbodiesel Pickups
Many newer over-the-road trucks come factory-filled with 10W-30 for improved fuel economy. Heavy-Duty 10W-30 is ideal for customers who want to maintain the improved fuel efficiency afforded by a 10W-30.
It also provides outstanding protection for smaller off-road equipment and turbodiesel pickups specifying 10W-30 (Ford** specifies 10W-30 for normal service).
- 4X more engine protection*
- Excellent opportunity for price-conscious customers to move up to AMSOIL quality
- Improved fuel economy
- Outstanding protection for OEM-recommended drain intervals
Signature Series 0W-40 (DZF)
- Diesel-Powered Vehicles and Equipment Operating in Cold Climates
Signature Series 0W-40 is formulated specifically for applications operating in extreme cold. Most over-the-road trucks and heavy equipment are parked outside. Signature Series 0W-40 provides the ultimate cold-weather protection and performance, helping engines turn over faster and reducing start-up wear.
- 4X better cold-temperature performance***
- Reduces unnecessary idle time. Engines can be shut down with confidence of restart.
- Extra protection for extended drain intervals
Signature Series 5W-40 (DEO)
Heavy-Duty 5W-40 (ADO)
- Turbodiesel Pickups
- Over-the-Road Trucks

Signature Series 5W-40 and Heavy-Duty 5W-40 are ideal for turbodiesel-pickup, over-the-road-truck and heavy-equipment owners who want the cold-weather and fuel-economy benefits of a 5W and the protection benefits of an SAE 40.
- Outstanding cold-cranking ability and start-up protection
- Excellent fuel economy
Heavy-Duty 5W-40
- 4X more engine protection*
- Excellent opportunity for price-conscious customers to move up to AMSOIL quality
- Outstanding protection for OEM-recommended drain intervals
Signature Series 5W-40
