The DT Ram 1500 moved every engine to a top-mounted cartridge oil filter, which is actually good news: no filter wrench fights in a wheel well, no oil running down your arm. On the 3.6 Pentastar and 5.7 Hemi you need one 24 mm cap-style socket and a 13 mm socket for the pan plug, and the truck sits high enough that many owners never jack it up. The EcoDiesel is the same idea but with a bigger cap, more than 10 quarts of oil, and a diesel-specific oil spec you cannot substitute.
What people get wrong is torque and O-rings. The filter housing and cap are plastic, so 18 ft-lb on the gas engines is the whole story — an impact gun or a bar-length ratchet will crack it and you'll be buying a housing. And the small O-ring that comes in the filter box is not optional; reusing the old one is why so many DT owners chase a mystery drip on the front of the engine. Finish by resetting the oil life counter in Uconnect, or the reminder logic stays out of sync.

3.6 Pentastar and 5.7 Hemi both use a 24 mm cap-style socket for the cartridge housing and a 13 mm oil pan drain plug; capacities are 5.9 qt of 0W-20 and 7 qt of 5W-20 respectively. The 3.0 EcoDiesel uses a larger filter cap (verify the size on your truck), holds roughly 10.5 qt, and requires 5W-30 meeting MS-12633 — a different filter, different cap socket and a much bigger drain pan.
| Oil pan drain plug (3.6 and 5.7) | 20 ft-lb (27 Nm) — verify in the service manual |
| Oil filter housing cap (3.6 and 5.7) | 18 ft-lb (25 Nm) |
| Oil pan drain plug (3.0 EcoDiesel) | verify in the service manual |
| Oil filter housing cap (3.0 EcoDiesel) | verify in the service manual |
The 24 mm cap socket for the 3.6 and 5.7 cartridge housings and the 13 mm gas-engine drain plug are well established, but the 3.0 EcoDiesel cap and plug sizes vary by build — measure yours or check the manual before buying tools, and confirm capacity on your specific engine.
The 3.6 Pentastar and 5.7 Hemi cartridge housing caps take a 24 mm cap-style filter socket on a 3/8 in drive. The 3.0 EcoDiesel uses a larger cap, so confirm the size before buying.
7 US quarts of SAE 5W-20 meeting Chrysler MS-6395, filter included. The 3.6 Pentastar takes about 5.9 quarts of 0W-20, and the 3.0 EcoDiesel takes roughly 10.5 quarts of 5W-30 MS-12633.
On Uconnect-equipped trucks go to the Vehicle or Settings menu, find Oil Life, and choose Reset. Alternatively, with the ignition in Run and the engine off, fully press the accelerator three times within 10 seconds.
Usually no. The DT's ride height lets most people reach the 13 mm drain plug by sliding underneath, and the filter is on top of the engine. If you do lift it, use jack stands on the front frame rails and chock the rear wheels.
