For the 2009 Dodge Ram 2500 HD Pickup with the 6.7L 6-Cylinder Diesel Turbo (Engine Code L), the engine oil capacity is 12 quarts with a filter change. The preferred viscosity for temperatures above -18°C is SAE 15W-40, though AMSOIL recommends using SAE 5W-40 synthetic engine oil for all temperatures to prevent severe engine damage in ambient temperatures below 0°F (-18°C). A primary recommendation is AMSOIL Signature Series 5W-40 Max-Duty Diesel Oil paired with an AMSOIL oil filter.
What oil does a 2009 Dodge Ram 2500 HD 6.7L take?
This vehicle requires diesel engine oil that meets API CJ/CK-4 or Cummins CES 20081 standards. For temperatures above -18°C, SAE 15W-40 is preferred. However, for operation in all temperatures, including those below 0°F (-18°C), AMSOIL recommends using a synthetic 5W-40 oil to prevent severe engine damage.

How much oil does it take with a filter change?
The total capacity for the 6.7L diesel engine is 12 quarts when including the oil filter. When performing an oil change, follow these steps to ensure accuracy:
- Start and run the engine until it reaches 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 with additional oil as needed.
Common diesel oil-related concerns and how AMSOIL products may help
Maintaining a heavy-duty Cummins diesel requires addressing specific operational stresses like high heat and soot loading.
| Concern | Why it matters | AMSOIL Product | How it may help | Limitation |
|---|---|---|---|---|
| Extreme Temperatures | Cold starts can cause damage below 0°F. | Signature Series 5W-40 | Excels in extreme temperatures. | Requires proper viscosity selection. |
| Engine Wear | High pressure and friction wear components. | Signature Series 5W-40 | Delivers up to 6X more wear protection. | Not a repair for existing damage. |
| Contaminants | Small particles can cause abrasive wear. | AMSOIL Oil Filter | 99% efficiency at 20 microns. | Must be changed per service intervals. |
Diesel maintenance notes for this vehicle
Owners of the 6.7L Cummins diesel should prioritize high-quality filtration and cooling system integrity. Because these engines are often used for heavy towing or hauling, fluid service intervals are critical to managing engine stress. Key areas of focus include:
- Filtration: Using high-efficiency oil and air filters to manage soot and environmental contaminants.
- Cooling System: Maintaining coolant integrity to protect all metals, gaskets, and hoses.
- Turbocharger Health: Ensuring proper lubrication is maintained to support turbocharger longevity.
Common maintenance concerns for this vehicle
Based on owner reports and historical context, several areas require regular inspection:
- Electrical Systems: Some owners have reported issues with battery charging or electrical ground shorts.
- Exhaust Components: Reports of abnormal exhaust odors may indicate the need for manifold bolt inspections.
- Engine Cooling/Heating: Monitoring the intake air heater and overall cooling system integrity is advised.
Note: These are owner reports and should not be treated as verified defects.
Recall, TSB, and manufacturer communication notes
NHTSA research indicates 5 recall records for the 2009 Dodge Ram 2500. One notable campaign (16V352000) involves frontal passenger-side air bag inflator modules that may rupture due to propellant degradation. Owners should verify their specific VIN through official Chrysler/Stellantis or NHTSA channels to check for open recalls.
About this vehicle
The 2009 Dodge Ram 2500 HD is a heavy-duty pickup truck produced during a transitional era for Stellantis North America (formerly part of Chrysler Group LLC). During this period, the Ram nameplate was still officially marketed under the Dodge brand, as the Ram Trucks division did not become a standalone brand until 2010.
This model is defined by its 6.7L diesel engine from the Cummins engine family. Cummins Inc., based in Columbus, Indiana, is the primary manufacturer of these engines. The partnership between Dodge/Ram and Cummins has historically provided the high torque necessary for commercial applications and heavy towing. Because this era moved toward more complex emission standards, owners often focus on rigorous fuel system care, turbocharger inspections, and emissions monitoring to maintain engine longevity.
As a 2500 series model, it is designed for higher payload and towing capacities compared to the light-duty Ram 1500. When sourcing parts, it is important to cross-reference the vehicle’s VIN or owner’s manual to ensure compatibility with specific engine codes like ‘L’.
Common questions about this vehicle’s diesel oil and maintenance
What is the oil capacity for my 2009 Ram 2500 6.7L?
The capacity is 12 quarts when changing the oil with a new filter.
Can I use 15W-40 in my diesel Ram?
Yes, SAE 15W-40 is preferred for temperatures above -18°C. However, if you operate in temperatures below 0°F (-18°C), AMSOIL recommends using a synthetic 5W-40 oil to avoid severe engine damage.
What oil specification does the Cummins 6.7L require?
The AMSOIL lookup note references API CJ/CK-4 and MS-10902 standards, and notes that oil meeting Cummins CES 20081 may also be used.
How often should I change my oil filter?
While specific intervals depend on usage, using high-quality filters like the WIX XP Oil Filter can support drain intervals up to 25,000 miles under certain conditions.
What should I do if my check engine light comes on?
If the light illuminates, it could indicate various issues ranging from exhaust manifold bolts to electrical faults. You should have the vehicle diagnosed by a professional technician.
How can I verify if my truck has an active recall?
You should always check your specific Vehicle Identification Number (VIN) through the official NHTSA website or contact a certified Dodge/Ram dealer to ensure all safety recalls are addressed.
