Automatic Transmission Fluid Capacities
For the 6-speed 68RFE transmission:
- Total Fill Capacity: 17.5 quarts
- Initial Fill (4WD): 6.6 quarts
- Initial Fill (RWD): 5.5 quarts
How much oil does it take with a filter change?
For the 6.7L Diesel engine, the total capacity is 12 quarts when replacing the filter. It is important to follow proper filling procedures: after filling, start and idle the engine for several minutes to check for leaks. Stop the engine and wait 30 minutes to allow the oil to drain back into the pan before re-checking the level.
Diesel maintenance notes for this vehicle
Maintaining a Cummins diesel engine requires attention to specific filtration and cooling needs. Because these vehicles are often used for heavy towing or hauling, high-quality lubricants are vital for longevity.
- Low Ash Requirement: The AMSOIL lookup specifies that low ash diesel engine oil is required for this application.
- Coolant Capacity: The cooling system capacity is 22 quarts.
- Filter Efficiency: Using high-quality filters like the AMSOIL Oil Filter (EAO80-EA) provides 99 percent filtering efficiency at 20 microns.
Common diesel oil-related concerns and how AMSOIL products may help
| Concern | Why it matters | AMSOIL Product | How it may help | Limitation |
|---|---|---|---|---|
| Engine Wear | High-stress diesel operation causes friction. | Signature Series (DTTQT-EA) | Delivers up to 6X more wear protection. | Requires regular service intervals. |
| Contamination | Small particles can damage engine components. | AMSOIL Oil Filter (EAO80-EA) | Provides 99% efficiency at 20 microns. | Must be replaced per schedule. |
| Extreme Temperatures | Viscosity changes can affect lubrication. | Signature Series (DTTQT-EA) | Excels in extreme temperatures. | Not confirmed for all specific climates. |
Common maintenance concerns for this vehicle
Owners of heavy-duty diesel trucks should regularly monitor several key areas to prevent downtime:
- Exhaust Aftertreatment: Modern diesel engines require careful monitoring of emission control systems.
- Fuel/Water Separation: Diesel fuel quality is critical; ensure fuel filters are inspected regularly.
- Cooling System Integrity: Check for leaks in gaskets and hoses to prevent overheating during heavy loads.
Recall, TSB, and manufacturer communication notes
NHTSA research indicates several recalls for the 2023 Ram 2500. Always verify your specific vehicle’s status using your VIN at the NHTSA website or through a certified dealer.
- Transmission Fluid Leak: A recall (Campaign 22V835000) was issued regarding potential pressure and heat build-up in the transmission that could lead to fluid leaks from the dipstick tube, posing a fire risk.
- Heater Grid Relay Short: A recall (Campaign 23V060000) affects Cummins 6.7L Turbo Diesel engines where an electrical short in the heater grid relay could cause an engine compartment fire.
- Reverse Display Function: A recall (Campaign 23V059000) involves the trailer reverse steering control module potentially preventing rearview images from displaying correctly.
Note: NHTSA complaints are owner reports and do not constitute confirmed defects.
About this vehicle
The 2023 Ram 2500 is a heavy-duty pickup truck belonging to the fifth generation of the Ram HD series. As part of the Ram Trucks division under Stellantis, this model is positioned as a high-capacity workhorse, designed for significant towing and hauling capabilities.
This vehicle utilizes a diesel powertrain associated with Cummins, an American manufacturer specializing in diesel engines and related components such as fuel systems, filtration, and emission controls. The integration of Cummins diesel technology into Ram Heavy Duty trucks has historically made this platform a primary choice for owners requiring high torque and durability for commercial or heavy-duty recreational use.
Because these vehicles are often subjected to high-stress environments—such as heavy towing, hauling large payloads, or long-distance transport—maintenance schedules are critical to longevity. Owners should focus on diesel-specific filtration requirements and exhaust aftertreatment system maintenance to ensure the engine meets modern emissions standards and remains reliable over time.
Common questions about this vehicle’s diesel oil and maintenance
What is the correct oil viscosity for my 2023 Ram 2500?
The AMSOIL lookup specifies 10W-30 for temperatures above -18°C and 5W-40 for temperatures below -18°C.
How often should I change my diesel oil?
While specific intervals depend on usage, products like AMSOIL Signature Series are designed to confidently extend drain intervals under heavy-duty conditions.
Does my Ram 2500 require low ash oil?
Yes, the AMSOIL lookup notes specifically state that low ash diesel engine oil is required for this application.
What should I do if I see a transmission fluid leak?
If you suspect a leak, contact a dealer immediately. NHTSA recall data (Campaign 22V835000) notes that some models may experience leaks from the dipstick tube due to pressure build-up.
Can I use any antifreeze in my coolant reservoir?
It is best to use a compatible product. AMSOIL recommends their Passenger Car & Light Truck Antifreeze, which is compatible with all other antifreeze and coolant colors.
How do I verify if my truck has an open recall?
You should contact a certified Ram dealer or visit the NHTSA website to check your specific VIN for any active recalls or manufacturer communications.
