Ram 3500 Oil Change Specifications
The Ram 3500 offers the same 6.4L HEMI V8 and 6.7L Cummins Turbo Diesel engines as the 2500 — and the Cummins High-Output in the 3500 delivers up to 1,075 lb-ft of torque, the most in the class. Heavy-duty service intervals and diesel-spec oil are essential. Our Cummins-trained technicians handle every 3500.

Oil Change Tips for Your Ram 3500
- Cummins HO owners: maximum torque application accelerates everything — be conservative with intervals.
- Dually (DRW) trucks have higher payload ratings — increased duty cycle means severe-duty intervals.
- Use diesel-spec oil meeting CES 20081 — never substitute light-duty gas oil.
- Fuel filter, water separator, and DEF service are all part of the diesel maintenance schedule.
- HEMI 6.4L requires 0W-40 specifically.
