2018 RAM 2500 Oil Capacity
The 2018 Ram 2500 oil capacity depends on the engine: the 5.7L HEMI EZC and 6.4L HEMI each take 7.0 qt, while the 6.7L Turbo Diesel takes 12.0 qt. Use the matching engine entry rather than treating one capacity as correct for every truck.
The figures are the listed oil capacities, and the viscosity grade is shown alongside each engine: 5W-20 for the 5.7L HEMI EZC, 0W-40 for the 6.4L HEMI, and 5W-40 for the 6.7L Turbo Diesel. Match both the engine and its specified oil when selecting a service fill.
These figures apply to the listed 2018 engine options; capacity and oil grade can differ by engine and model year. If you are unsure which engine your truck has, or need a figure not listed here, confirm it on the door jamb or in the owner's manual.
