What's the 2015 Ram 3500 6.7 Cummins oil capacity?

The 2015 Ram 3500 6.7L Cummins Diesel takes 12 quarts of either SAE 5W-40 if driven in temperatures below 0 degrees F or 15W-40 when driven in temps above 0 F. It is very important that You follow these recommendations because if You dont use 5W-40 when temperatures drop below 0 F You are running a serious risk of causing severe engine damage. You will also need an oil filter to complete the service, a WIX57620-EA filter is recommended along with using fully synthetic motor oil. The process to change the oil is no different than any other vehicle, just make sure to properly tighten the oil drain plug to 37 ft-lbs or torque when You reinstall it.
