Diesel maintenance notes for this vehicle

  • Oil Specification: Use API CJ/CK-4 oil that meets specification standards MS-10902. Oil meeting Cummins CES 20081 standards may also be used.
  • Ash Content: Low ash diesel engine oil is required for this application.
  • Turbocharger Care: Given the turbocharger component, monitoring lubrication integrity is critical to prevent premature turbo failure.
  • Filtration: Maintenance should prioritize high-quality filtration systems (such as fuel/water separators) and specific oil viscosities designed for diesel combustion environments.

Common diesel oil-related concerns and how AMSOIL products may help

Diesel engines face unique stresses including soot loading and extreme temperatures. The following table outlines how specific AMSOIL products address these needs.

Concern Why it matters AMSOIL Product How it may help Limitation
Turbocharger Wear High heat and high RPMs can cause turbo failure. DEOQT-EA Provides outstanding extreme-pressure protection. Requires proper service intervals.
Engine Wear Diesel combustion creates high friction environments. DEOQT-EA Delivers up to 6X more wear protection. Not a repair for mechanical damage.
Extreme Temperatures Fluctuating temps affect viscosity and engine start. ADOQT-EA Excels in extreme temperatures. Not a repair for mechanical damage.

Common maintenance concerns for this vehicle

Based on NHTSA consumer reports, owners of the 2015 Ram 1500 have noted several areas for monitoring:

  • Steering: There are reports regarding intermittent loss of power steering assist and stiffness.
  • Braking Systems: Some users reported spongy brake pedals or ABS module issues.
  • Fuel/Propulsion: Diesel fuel system components are a noted area of interest in consumer complaints.

Note: NHTSA complaints are owner reports and should not be treated as verified defects.

Recall, TSB, and manufacturer communication notes

Official research indicates the following recall information for 2015 Ram 1500 models:

  • Engine/Cooling Recall (Campaign 20V475000): Certain 3.0L diesel engines may have a crankshaft position sensor tone wheel that delaminates, potentially causing an engine stall. The remedy involves a powertrain control module software update.
  • Tailgate Latch/Structure: There are recalls regarding tailgate actuator limiter tabs fracturing or power locking tailgate issues (Campaigns 19V347000 and 18V486000).

Important: Always verify your specific vehicle’s open recalls by using your VIN through an authorized dealer or the NHTSA website.

About this vehicle

The 2015 Ram 1500 pickup represents a significant era in the fourth generation of the Ram truck line. Following its spin-off from Dodge to become a standalone division under Stellantis North America (formerly FCA US LLC), the 2015 model year continues a legacy of versatility for both daily driving and work-oriented applications.

This specific configuration features the 3.0L 6-cylinder diesel turbo engine (Engine Code [M] EXF M). While NHTSA vPIC records may show discrepancies in standard model listings, this diesel variant is specifically designed for users requiring increased towing capacity or improved fuel efficiency compared to gasoline counterparts. Because it utilizes a turbocharger, maintaining lubrication integrity and following specialized diesel service intervals—including high-quality filtration and correct oil viscosity—is critical to ensuring the longevity of the engine and its forced induction components.

Owners often research this vehicle due to its role in both consumer and light commercial sectors. Proper maintenance of the 8HP70 transmission and the cooling system is also vital for maintaining the reliability expected from a diesel-powered work truck.

Common questions about this vehicle’s diesel oil and maintenance

How much oil does my 3.0L Ram diesel take?

It takes 10.6 quarts of oil when replacing the filter. Always check your level after refilling.

What is the correct oil viscosity for the 2015 Ram 1500 3.0L Diesel?

The recommended viscosity is 5W-40 for all temperatures.

Can I use standard gasoline engine oil in my diesel Ram?

No. This engine requires low ash diesel engine oil that meets API CJ/CK-4 and Cummins CES 20081 standards as noted in the AMSOIL lookup.

What is the torque spec for the oil drain plug?

The oil drain plug should be torqued to 33 ft/lbs.

How often should I change my transmission fluid?

While specific intervals vary by use, the AMSOIL lookup identifies the 8HP70 transmission as requiring an 8.8-quart total fill of appropriate synthetic fluid.

How do I check for active recalls on my Ram 1500?

You should contact a dealer or visit the NHTSA website and provide your VIN to ensure you are aware of any manufacturer communications or safety recalls.
