2016 Ram 3500 — Oil Capacity & Filter Specs

The 2016 Ram 3500 takes 7.0 quarts (6.6 liters) with the 6.4L HEMI gas V8 and 12.0 quarts (11.4 liters) with the 6.7L Cummins turbo-diesel, both including the filter.

Quick answer

• Oil capacity (with filter):
  • 6.4L HEMI V8: 7.0 qt (6.6 L)
  • 6.7L Cummins I‑6: 12.0 qt (11.4 L)
• Recommended oil weight/viscosity:
  • 6.4L HEMI: SAE 0W‑40, full synthetic
  • 6.7L Cummins: SAE 15W‑40 for most temps; 5W‑40 full synthetic preferred for cold climates/extended idling
• Oil type/spec:
  • 6.4L HEMI: Oil meeting FCA MS‑12633 and API SN (or newer SP)
  • 6.7L Cummins: Heavy‑duty diesel oil meeting API CJ‑4 or CK‑4; Cummins CES 20081/20086 approved
• Oil filter (OEM and popular aftermarket):
  • 6.4L HEMI: OEM Mopar filter — consult dealer with VIN for the correct part number. Common aftermarket equivalents: Fram XG10060; Wix 57060; Mobil 1 M1‑113A (verify by VIN/application).
  • 6.7L Cummins: OEM Mopar/Cummins filter — consult dealer with VIN for the correct part number. Common aftermarket equivalents: Fram PH3976A; Wix 57620 (verify by VIN/application).

Capacity by engine option

Oil change interval

• Normal service
  • 6.4L HEMI: Follow the Oil Life Monitor (OLM), typically up to 8,000–10,000 miles or 12 months with 0W‑40 that meets MS‑12633.
  • 6.7L Cummins: Up to 15,000 miles/12 months or per OLM/engine hours (whichever comes first). Use CK‑4/CJ‑4 oil and a quality filter.
• Severe service (frequent towing/hauling, dusty conditions, lots of idling/short trips, extreme temps)
  • 6.4L HEMI: 4,000–5,000 miles or 6 months.
  • 6.7L Cummins: 7,500 miles or 6 months, or sooner if fuel dilution or soot loading is suspected. High‑idle PTO use should follow an hours‑based schedule per the manual.

Always default to the OLM/owner’s manual if it calls for shorter intervals based on driving conditions.

Drain plug torque

• 6.4L HEMI V8: 25 ft‑lb (34 N·m) on the oil pan drain plug.
• 6.7L Cummins I‑6: 31 ft‑lb (42 N·m) on the oil pan drain plug.

Crush washer/gasket note: Many HEMI drain plugs use an integral/rubber‑coated sealing washer that can be reused if undamaged; replace the plug or gasket if cut or flattened. Cummins plugs typically use a separate sealing washer—replace it if crushed or leaking. Always clean the mating surface and verify no double‑stacked washers.

How to change the oil

1. Warm the engine briefly, then shut off and set the truck securely on level ground. Chock wheels.
2. Remove the skid plate (if equipped) for access. Place a large drain pan (12+ qt for diesel).
3. Remove the oil fill cap, then the drain plug. Let oil drain completely.
4. Replace the crush washer/seal as needed; torque the drain plug to spec (see above).
5. Spin off the oil filter. Lightly oil the new filter’s gasket and install hand‑tight, then an additional 3/4 turn (or to the filter manufacturer’s torque spec if provided).
6. Fill with the correct amount/grade of oil for your engine (see capacities above).
7. Start the engine, check for leaks, then shut off and recheck level. Top off as needed.
8. Reset the Oil Life Monitor from the dash menu.

Common issues / tips for this generation (2013–2018 Ram HD)

• 6.7L Cummins fuel dilution/soot: Extended idling and frequent DPF regens can thin the oil. If the oil level rises on the dipstick or smells like diesel, shorten intervals and use a CK‑4 5W‑40 synthetic in cold or high‑idle duty.
• 6.4L HEMI lifter/cam wear concerns: This engine is sensitive to oil quality. Stick to 0W‑40 that meets MS‑12633 and avoid extended intervals if you tow or idle a lot.
• Oil cooler and line seepage: Watch for dampness around the oil cooler/adapter or cooler lines on both engines—tighten to spec or replace seals as needed.
• Filter access and mess control: On the Cummins, use a filter cap or bag to avoid spills. Pre‑fill is optional; if you do, only fill the outer ring to prevent introducing unfiltered oil.
• Skid plates and splash shields: Reinstall and torque any skid plate hardware; missing shields can lead to debris contacting the filter.
• Always verify parts by VIN: Ram used running changes; oil filter part numbers can vary by build date. When in doubt, call the dealer with your VIN or check a reputable parts catalog.
