Quick Answer: What oil does a 2007 Dodge Ram 2500 HD 6.7L Diesel take?
Engine Oil Specifications and Details
Proper lubrication is critical for the longevity of the 6.7L Cummins diesel engine. Using the correct viscosity and meeting required standards helps prevent premature wear.
What oil viscosity should I use?
| Condition | Recommended Viscosity |
|---|---|
| Above -18°C | SAE 15W-40 (Preferred) |
| All Temperatures | SAE 5W-40 Synthetic (Required below 0°F / -18°C to prevent damage) |
How much oil does it take with a filter change?
The engine requires 12 quarts of oil when changing with a new filter. To ensure accuracy during an oil change, follow these steps:
- Run the engine to operating temperature.
- Stop the engine and wait approximately 30 minutes to allow oil in the upper engine parts to drain back into the pan.
- Check the oil level and top off as needed.
Oil Drain Plug Torque: 37 ft/lbs.
Diesel maintenance notes for this vehicle
Maintaining a heavy-duty diesel requires attention to filtration and fluid integrity. For the 6.7L Cummins engine, owners should focus on:
- Low Ash Requirement: The AMSOIL lookup note specifies that low ash diesel engine oil is required for this application.
- Filtration: High-quality filters like the AMSOIL Oil Filter provide 99 percent filtering efficiency at 20 microns to help reduce engine wear.
- Air Intake: Maintaining clean air filtration via WIX or Donaldson P-Series filters is essential for turbocharger health and engine longevity.
Common diesel oil-related concerns and how AMSOIL products may help
| Concern | Why it matters | AMSOIL product from this lookup | How it may help | Important limitation |
|---|---|---|---|---|
| Extreme Temperatures | Viscosity changes can cause damage during cold starts or high heat. | DMEQT-EA | Excels in extreme temperatures and maintains proper viscosity. | Must use 5W-40 below 0°F. |
| Engine Wear | Diesel engines face high pressure and soot loading. | DMEQT-EA | Delivers up to 6X more wear protection. | Requires regular oil changes. |
| Contaminants | Small particles can cause abrasive wear. | EAO80-EA | Provides 99% efficiency at 20 microns. | Filter must be replaced per interval. |

About this vehicle
The 2007 Dodge Ram 2500 HD is a heavy-duty 3/4-ton pickup truck designed for high-capacity tasks, including significant towing and hauling. This model year features the 6.7L diesel engine from the Cummins family, which is widely recognized for its durability and high torque output in commercial and recreational applications.
Because this vehicle utilizes a large-displacement turbo diesel, maintenance focus typically shifts toward specialized requirements compared to standard gasoline engines. Owners should prioritize research into fuel system integrity, air filtration, and cooling system maintenance. Due to the complexity of the 6.7L diesel engine and its associated emission control systems, diligent monitoring of service intervals for turbocharger components, fuel injectors, and heavy-duty filtration systems is recommended to ensure powertrain longevity.
Common questions about this vehicle’s diesel oil and maintenance
What is the correct oil viscosity for my 2007 Ram 2500 6.7L?
SAE 15W-40 is preferred for temperatures above -18°C. However, if you operate in ambient temperatures below 0°F (-18°C), you must use SAE 5W-40 synthetic engine oil to avoid severe engine damage.
