The 2014 Ram 2500 with the 6.4L Hemi generally runs on synthetic 5W-20 engine oil, with an approximate capacity of 7 quarts (about 6.6 liters) including the oil filter. Always confirm the exact specification for your vehicle by checking the oil filler cap and the owner's manual, since climate and towing conditions can influence the recommended viscosity.
Recommended oil type and standards
Chrysler/Ram specifies synthetic 5W-20 oil for the 6.4L Hemi in the 2014 Ram 2500. The oil should meet API SN or newer and ILSAC GF-5 standards. A high-quality synthetic-blend 5W-20 or full synthetic that complies with these standards is acceptable. If your local dealer or manual suggests a different option for unusual conditions, follow that guidance and avoid mixing viscosities.
Cold-weather considerations
In colder climates, the 5W-20 specification remains the baseline recommendation because it supports easier cold starts and quicker lubrication. If your manual permits an alternative due to extreme temperatures, follow the exact guidance provided for your VIN.
Hot-weather and towing considerations
For hot climates or when towing heavy loads consistently, some technicians may opt for a slightly higher viscosity within the manual’s allowances (for example, 5W-30) to maintain oil film integrity under higher temperatures. Always verify any viscosity deviation with the owner's manual or a Ram service representative.
Oil capacity and change intervals
The engine oil capacity for the 6.4L Hemi is about 7 quarts (6.6 L) including the filter. Routine oil-change intervals are guided by the vehicle’s Oil Life Monitoring System and the driving conditions. Under normal use with synthetic oil, many owners see intervals around 7,500 miles (about 12,000 km) or longer, while severe driving conditions (extensive towing, high heat, frequent short trips) typically require shorter intervals. Always follow the interval shown on the vehicle’s information display and refer to the owner’s manual for the exact schedule.
How to confirm the exact specification for your vehicle
For the most precise guidance, consult your owner’s manual, which lists the recommended viscosity, oil quality standards, and capacity for your specific vehicle. The oil filler cap on the engine often indicates the correct viscosity (for example, 5W-20). If you no longer have the manual, a Ram dealership or certified service center can confirm the exact specification for your VIN and regional climate.
Summary
In brief: use synthetic 5W-20 motor oil for a 2014 Ram 2500 with the 6.4 Hemi, with an oil capacity of roughly 7 quarts including the filter. Verify the exact viscosity and interval in the owner’s manual or at a Ram service center, especially if you tow heavily or operate in extreme temperatures. Following the factory guidance and using a high-quality oil will help protect the engine and maintain performance.

Can you use 5W-30 in a 6.4 Hemi?
In the manual for the 2500+s it says to run 5w30 only in the 5.7 and 6.4. It says to run 5w20 in the 1500s because it gives them extra good boy points with the EPA and they pay less of a penalty because of the slight MPG gains.
