About this vehicle
The 2009 Dodge Ram 3500 represents a significant era in the history of heavy-duty American pickups. During this period, the ‘Ram’ nameplate was still marketed under the Dodge brand, prior to its official spin-off into a standalone division in 2010.
As a heavy-duty model, the 3500 is positioned within the Ram lineup to handle substantial towing and payload requirements, often serving as a chassis cab or a high-capacity pickup truck. Central to this vehicle’s identity is its diesel powertrain. The presence of a Cummins diesel engine places this vehicle within a well-known lineage of industrial-grade powerplants.
Cummins Inc., an American multinational corporation, is a primary provider of these diesel engines and specializes in fuel systems, filtration, and emission control components. For owners of this 6.7L diesel variant, understanding the relationship between the engine manufacturer (Cummins) and the vehicle manufacturer (Dodge/Stellantis) is vital for sourcing correct parts.
Typical use cases for a Ram 3500 include heavy-duty commercial work, large-scale towing, and agricultural applications. Because these vehicles are often subjected to high-stress environments, maintenance focus typically shifts toward robust filtration systems, engine control units (ECUs), and fuel system integrity. Owners researching this vehicle should prioritize looking into the specific service intervals for diesel-specific components, such as fuel filters and oil quality, which are critical for maintaining long-term engine health.
Note: Because research snippets focus on broader model generations, specific mechanical tolerances or exact fluid capacities should be verified via a dedicated service manual.
Common questions about this vehicle’s diesel oil and maintenance
How much oil does my 2009 Ram 3500 6.7L take?
It takes 12 quarts of oil when performing a change that includes the oil filter.
What is the correct oil viscosity for cold weather?
For temperatures below 0°F (-18°C), you should use SAE 5W-40 synthetic engine oil to prevent severe engine damage. For temperatures above -18°C, SAE 15W-40 is preferred.
What are the required oil specifications?
The AMSOIL lookup note references API CJ/CK-4 and MS-10902 standards. It also notes that Cummins CES 20081 standards may be used.
How can I extend my engine life?
