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
  • Heavy Equipment

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

  • 6X more engine protection*
  • Ideal for customers seeking the ultimate wear protection in severe operating conditions
  • Extra protection for extended drain intervals

 

Signature Series 15W-40 (DME)

 

Heavy-Duty 15W-40 (ADP)

  • Over-the-Road Trucks
  • Off-Road Equipment
  • Turbodiesel Pickups

Signature Series 15W-40 and Heavy-Duty 15W-40 are the primary recommendations for most on- and off-road heavy-duty diesel applications in the marketplace; 15W-40 is the most widely used viscosity in the diesel world.

  • Reduced oil consumption
  • Outstanding shear stability, ensuring superior viscosity retention and wear protection in the most severe environments

 

Heavy-Duty 15W-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 15W-40

  • 6X more engine protection*
  • Ideal for customers seeking the ultimate wear protection in severe operating conditions
  • Extra protection for extended drain intervals

Z-ROD® Keeps Classic Vehicles Street-Ready

Written by Ches Cain

Vintage Car and Cam Wear Problems Solved – Zinc Fortified Motor Oils

After this long Sioux Falls winter, making the transition from storage to the street can be an anxious time for classic car owners. Even after extensive preparations, doubts may linger whether a prized vehicle has been effectively protected during a period of inactivity. Many owners now look to modern technology to keep vintage hot rods and muscle cars performing at a high level on the street and fully protected during storage.

Protecting engines designed decades ago- and engines modified for increased performance- can be challenging. From flat-tappet cams and splash-lubricated components to the toll of periodic storage, unique issues must be addressed.

Amsoil Z-Rod high Zinc oil

Flat-Tappet Cams and ZDDP

The design of flat-tappet cams makes them especially vulnerable to wear. As the name indicates, the tappet- or lifter – is flat. During operation the surface of the cam lobe slides rapidly over the surface of the tappet, producing high friction and temperatures. The camshaft and lifters are responsible for triggering the precisely tuned movements of the valve train. Here, the use of anti-wear additives becomes crucial.

Stop Cam Wear – No Aftermarket Oil Additives Needed

Zinc dialkyldithiophosphate (ZDDP) is a commonly used motor oil additive that provides anti-wear protection and minimizes lubricant breakdown. ZDDP also exhibits mild extreme-pressure protection. As temperatures in an engine rise, ZDDP decomposes, and the resulting chemistry protects critical metal surfaces.

Without the protective film barrier provided by ZDDP, the cams and lifters wear from the force of operation, negatively affecting cam and valve operation. Because most V-8 engines of the muscle car era came standard with flat-tappet cams, the problem is prevalent to classic-car and hot rod owners.

In these applications, modern oils, such as AMSOIL synthetic motor oils, are capable of providing adequate wear protection after the engine has been broken in. But due to variables like severity of service and level of modification, AMSOIL primarily recommends high-ZDDP oils in these applications, such as Z-ROD® Synthetic Motor Oil. When breaking in a rebuilt or high-performance engine, AMSOIL recommends AMSOIL Break-In Oil, which contains high levels of ZDDP for added protection.

Rust and Corrosion

Moisture can be as devastating an engine contaminant as dirt or sludge. Vehicles subjected to long-term storage are especially vulnerable to humidity-driven rust and corrosion. AMSOIL Z-ROD® Synthetic Motor Oil is formulated with a unique blend of rust and corrosion inhibitors to ensure maximum protection during storage.

AMSOIL Z-ROD® Synthetic Motor Oil (ZRT, ZRF)

  • 10W-30 and 20W-50
  • Protects flat-tappet cams
  • Long-term rust and corrosion protection

AMSOIL Break-In Oil (BRK) SAE 30
