How much oil does a 2007 Dodge Ram 2500 diesel take?
The engine in the 2007 Dodge Ram 2500 diesel typically requires about 13 quarts (roughly 12.3 liters) of engine oil when the oil filter is included in the change. Fill to the full mark on the dipstick after servicing and adjust as needed based on the dipstick reading.
This article explains the official capacity and practical considerations for the 2007 Ram 2500 with a Cummins 5.9L diesel, including how much oil to pour, how to verify the level, and tips for choosing the right oil. The capacity can vary slightly depending on whether the filter is changed and how the drain is performed, so always confirm with the owner’s manual and the engine’s dipstick after a change.
Oil capacity specifics
Below are the commonly cited oil capacities for the 2007 Ram 2500 diesel. Use these as a baseline, but rely on the dipstick for the final check.
- 13 quarts (approximately 12.3 liters) with the oil filter included in the change.
- 12 quarts (approximately 11.4 liters) without the filter, if you do not replace the filter during the drain.
These figures reflect typical manual specifications for the 5.9L Cummins inline-six used in the 2007 Ram 2500. If you perform additional work that drains more oil or uses auxiliary coolers, the total may differ. Always verify the final level with the dipstick after letting the oil settle for a few minutes.
Choosing the right oil and service tips
Before selecting oil and scheduling a change, it’s helpful to know the common options and best practices for this engine.
- Viscosity options commonly used: 15W-40 diesel engine oil is the traditional choice for many climates and workloads. Synthetic-blend variants are also common.
- Full synthetic (e.g., 5W-40) can be used in colder climates or for high-mileage engines, but ensure the oil meets the API ratings suitable for diesel engines and follows Cummins/OEM guidance.
- Recommended API service categories include older CH-4/CJ-4 era oils (with compatibility for 2007-era diesels) or newer APIs that meet current diesel specifications. Check the manual for exact requirements in your region.
After an oil change, run the engine briefly, turn it off, wait a few minutes, and recheck the dipstick to confirm the level is within the full range. Dispose of used oil properly and replace the oil filter as part of a full service when indicated by mileage or hours of operation.
Additional notes for the 2007 Ram 2500
The 2007 Ram 2500 uses a Cummins 5.9L diesel engine. While the capacity figures above are typical, regional recommendations and dealer guidelines may vary slightly. Always follow the exact specification listed in your owner’s manual and use the dipstick as the ultimate authority on oil level. If you live in extreme temperatures or regularly tow heavy loads, consider the higher end of the oil viscosity recommendations and consult a professional for a personalized maintenance plan.
Summary
For a 2007 Dodge Ram 2500 diesel with a Cummins 5.9L, plan on about 13 quarts (12.3 liters) of engine oil when including the filter in the change, with 12 quarts (11.4 liters) if the filter isn’t replaced. Use the dipstick to verify the fill after an oil change, and choose an oil that meets the vehicle’s API/spec requirements, commonly 15W-40 or a suitable synthetic blend. Always consult the owner’s manual for the exact specification and follow proper handling and disposal procedures for used oil.
