2023 Ram 1500 Maintenance Schedule

The 2023 Ram 1500 (DT) is offered with a two-engine lineup for this model year—the 3.6L Pentastar V6 and the 5.7L HEMI V8, both available with the eTorque mild-hybrid system. Note that the 3.0L EcoDiesel V6 was not offered for 2023 (paused for recertification) and returned for the 2024 model year. All engines use a timing chain and the 8-speed TorqueFlite automatic, so there is no timing belt to replace. Ram relies on an oil-life monitor rather than a fixed oil interval; owners who tow, haul, or run in dust should follow the shorter severe-duty schedule.
Service Intervals
| Service | Interval | Est. Cost |
|---|---|---|
| Engine Oil & FilterThe oil-life monitor typically calls for service by 10,000 miles or 12 months. The 3.6L Pentastar takes 0W-20, while the 5.7L HEMI is spec'd for 5W-20 (verify on the cap or in the manual). Severe duty shortens the interval. | 10,000 mi / 12 mo | $60-$120 |
| Tire RotationRotate at every oil change to even out tread wear; 4WD trucks benefit most since all four tires share drive load. | 10,000 mi | $25-$60 |
| Brake Pads & Rotor InspectionInspect at each rotation; pads typically last 40,000-60,000 miles but wear faster under load. Front pad/rotor replacement runs $250-$500. | 15,000 mi | $0-$50 (inspection) |
| Brake Fluid FlushDOT 4 fluid absorbs moisture over time; a flush every ~3 years protects ABS hardware and towing brake performance even though it isn't on the fixed normal schedule. | 36 mo | $100-$180 |
| Engine Air FilterReplace around 30,000 miles, sooner in dusty or off-road use; a clogged filter costs power and fuel economy. | 30,000 mi | $30-$70 |
| 8-Speed Automatic Transmission FluidThe ZF 8HP is 'fill for life' on the normal schedule but specified at ~60,000 miles under severe/towing use; a 60k-75k fluid-and-filter service preserves shift quality. | 60,000 mi | $250-$450 |
| Rear Axle / Differential FluidInspect at 60,000 miles; trucks that tow should replace rear gear oil (plus front-axle and transfer-case fluid on 4WD) to prevent gear and bearing wear. | 60,000 mi | $120-$250 |
| Spark Plugs (gas engines)Pentastar and HEMI iridium plugs are rated near 100,000 miles; the HEMI's 16-plug design (two per cylinder) makes its service pricier. | 100,000 mi | $150-$400 |
| Coolant FlushLong-life OAT coolant is first changed around 10 years or 150,000 miles, then more frequently; fresh coolant protects the water pump and eTorque cooling circuit. | 150,000 mi / 120 mo | $120-$220 |
| Battery Inspection & ReplacementTest the 12V battery at 5 years; eTorque trucks add a 48V mild-hybrid pack that powers stop-start and light launch assist. | 60 mo | $150-$300 |
2023 Ram 1500 Oil Change Interval
The 2023 Ram 1500 oil change interval is every 10,000 miles or 12 months, whichever comes first (estimated cost $60-$120). The oil-life monitor typically calls for service by 10,000 miles or 12 months. The 3.6L Pentastar takes 0W-20, while the 5.7L HEMI is spec'd for 5W-20 (verify on the cap or in the manual). Severe duty shortens the interval.
What Happens If You Skip It
- Stretching oil changes past what the oil-life monitor calls for accelerates HEMI lifter/camshaft wear and Pentastar timing-chain wear, risking multi-thousand-dollar internal repairs.
- Neglecting 8-speed transmission fluid on a working truck leads to converter shudder, harsh shifts, and eventual gearbox failure costing $4,000+.
- Ignoring differential and transfer-case fluid on 4WD trucks causes gear whine, driveline binding, and costly axle rebuilds.
- Deferring brake fluid flushes lets moisture corrode ABS components and boil fluid under towing loads, extending stopping distances.
- Delaying spark plug replacement past 100,000 miles causes misfires that can overheat and destroy the catalytic converters.
Common Issues at Higher Mileage — 2023 Ram 1500
5.7L HEMI tick and lifter/camshaft wear remains the engine's known weak point; timely oil changes reduce but do not eliminate the risk.
eTorque 48V belt-starter-generator or mild-hybrid faults on gas trucks, showing up as stop-start failures and dash warnings.
Rear-axle and pinion-seal leaks on towing-heavy trucks; look for gear oil weeping at the differential cover.
Water-pump seepage and coolant loss; inspect during coolant service and replace preventively before overheating.
FAQ
