Ram 2500 Oil Change Interval & Oil Type
Compiled & reviewed by Nikolai Tsyrenov · Updated 2026-07-11
When to change the oil on a 2019-2025 (DJ) Ram 2500, and what oil it takes.
| Oil change interval | ~6,000 mi / 6 mo via oil-life monitor; do not exceed 8,000 mi / 12 mo / 350 hr. Severe/towing ~4,000-5,000 mi |
|---|---|
| Engine / oil | 6.4L HEMI V8 gas (primary) or 6.7L Cummins turbo-diesel; 5W-20 synthetic (gas); TorqueFlite/68RFE auto |
| Oil filter | Replace with every oil change |
Ram 2500 note: The 6.4L HEMI gas V8 is the primary engine; the 6.7L Cummins turbo-diesel runs different intervals — longer monitor-managed oil changes plus its own fuel/water separator and diesel fuel filters (~every 15,000-20,000 mi). These are work trucks: towing and severe duty shorten oil, transmission and coolant intervals sharply, so log service against your actual duty cycle, not just the odometer.
