Maintenance Procedure: After filling the oil, start the engine and idle for several minutes. Check for leaks. Stop the engine and wait 30 minutes to allow the oil to drain back into the pan before checking the level again.
Diesel maintenance notes for this vehicle
- Low Ash Requirement: A low ash diesel engine oil is required for this application.
- Filter Efficiency: The AMSOIL Oil Filter provides 99 percent filtering efficiency at 20 microns in accordance with ISO SO 4548-12.
- Extreme Temperatures: Using the correct viscosity (5W-40 vs 15W-40) based on ambient temperature is vital to prevent engine damage during cold starts.
Common diesel oil-related concerns and how AMSOIL products may help
Diesel engines operating under heavy duty cycles face unique lubrication challenges.
| Concern | Why it matters | AMSOIL Product | How it may help | Limitation |
|---|---|---|---|---|
| Engine Wear | High pressure in diesel engines can cause component scuffing. | Signature Series 5W-40 DEOQT-EA | Delivers up to 6X more wear protection based on Detroit Diesel DD13 testing. | Requires regular oil changes. |
| Extreme Temperatures | Viscosity changes can affect lubrication during startup or high heat. | Heavy-Duty 5W-40 ADOQT-EA | Excels in extreme temperatures to maintain protection. | Must match ambient temperature requirements. |
| Contaminants | Small particles can cause abrasive wear. | AMSOIL Oil Filter EAO80-EA | Provides greater capacity for small, wear-causing contaminants. | Does not replace regular service intervals. |
Common maintenance concerns for this vehicle
Based on NHTSA data, owners of the 2014 Ram 3500 should be aware of several areas of concern:
- Steering Linkage: There have been reports regarding steering components and drag link connections.
- Suspension & Power Train: These are among the most common complaint categories in owner reports.
- Wheel/Hub Integrity: Some owners have reported issues with wheel studs and hub damage, particularly when hauling heavy loads.

Recall, TSB, and manufacturer communication notes
Official NHTSA recall research for the 2014 Ram 3500 Pickup identified several campaigns:
- Steering Linkage: A recall (Campaign 19V021000) was issued because an outboard steering linkage jam nut may loosen, potentially causing a loss of steering control.
- Aftermarket Suspension: A recall (Campaign 18E096000) involves certain Streetcar ORV LLC aftermarket suspension kits that could result in a fractured steering drag link.
- Tailgate Latch: A recall (Campaign 19V347000) was issued for trucks where the tailgate actuator limiter tab may fracture, causing the tailgate to unlatch while driving.
Important: Always verify open recalls by using your specific Vehicle Identification Number (VIN) through official manufacturer or NHTSA channels.
About this vehicle
The 2014 Ram 3500 is a heavy-duty pickup truck designed for high-capacity tasks, including significant towing and payload requirements. It is engineered to sit above light-duty models in terms of capability, often serving commercial applications through both pickup and chassis cab configurations.
A defining characteristic of this model is its association with the Cummins 6.7L diesel engine. This power plant is widely recognized for its durability in heavy-duty environments. Because these vehicles are frequently subjected to high-stress operating conditions—such as commercial hauling, heavy-duty towing, and long-distance transport—they require rigorous maintenance schedules.
Owners should prioritize the following areas during routine service:
- Diesel Fuel System: Maintaining clean fuel through high-quality filtration to protect injectors.
- Emission Systems: Monitoring exhaust and emissions control components.
- Fluid Management: Regular inspection of engine oil, coolant, and transmission fluids suitable for heavy-duty cycles.
- Turbocharger Maintenance: Ensuring proper lubrication and airflow integrity.
Technical details regarding specific performance outputs should be verified through official manufacturer service manuals to ensure accuracy during maintenance.
Common questions about this vehicle’s diesel oil and maintenance
How much oil does my 2014 Ram 3500 6.7L take?
It takes 12 quarts of oil when performing a service that includes a filter change.
What is the correct oil viscosity for cold weather?
If ambient temperatures are below 0°F (-18°C), you should use SAE 5W-40 synthetic engine oil to avoid severe engine damage. For temperatures above -18°C, 15W-40 is recommended.
What oil specifications does the Cummins engine require?
The AMSOIL lookup note references API CJ/CK-4 standards and MS-10902. It also notes that oil meeting Cummins CES 20081 standards may be used.
Can I use a standard oil filter?
While many are available, AMSOIL recommends filters like the EAO80-EA for high efficiency or WIX XP options for extended drain intervals.
How often should I change my diesel oil?
While specific intervals depend on usage, AMSOIL products like the Signature Series are designed to help confidently extend drain intervals under heavy-duty conditions.
Is there a torque spec for the oil drain plug?
Yes, the oil drain plug should be torqued to 37 ft/lbs.
