2027 Dodge Durango Maintenance Schedule
Engine, Mileage and Time Requirements for Scheduled Service
Proudly serving Brevard, Asheville, Hendersonville, Fletcher & Cherokee NC
2027 Dodge Durango Scheduled Maintenance Overview
Plan your 2027 Dodge Durango service around the engine, mileage, elapsed time and way you drive. The schedule below draws from the manufacturer-authored owner’s manual and keeps normal, severe-use and equipment-specific work identified. The 2027 manual expressly includes the 6.4L and 6.2L performance-engine maintenance plan. Both use the 6,000-mile/six-month oil limit and spark-plug replacement at 60,000 and 120,000 miles. Use this performance-engine plan separately from the 5.7L engine’s intervals. Our service team in Brevard can review your records, identify the applicable engine and help plan the next visit before a warning or worn component becomes a larger problem.
Oil-service guidance: 5.7L: max 10,000 miles / 12 months / 350 hours; 6.4L/6.2L: max 6,000 miles / 6 months. Follow an earlier oil-change message and use the mileage, time or engine-hour limit reached first. A maintenance-grid column is not permission to extend an oil change past its maximum. Tell your advisor about towing, short trips, dust, idling and temperature extremes. Rotate tires at the first sign of irregular wear, following the rotation pattern allowed by the installed tires and wheels.

Time-Based and Engine-Specific Service
Use the time limit as well as the mileage shown in the applicable row. Spark-plug footnotes are mileage-based only. Coolant service uses the written ten-year/150,000-mile limit unless a separate engine row specifies otherwise.
- Brake-fluid timing must follow the plan and fluid specification for your vehicle
- Never extend oil service to the next air-filter or spark-plug milestone
- Inspections mean check condition and replace only where the plan requires or condition warrants
- Keep dated service records with the mileage and engine hours, where tracked
Engine-Specific Maintenance Details
Use the oil specification and fill that match the installed engine. The table covers 5.7L V8, 6.4L V8, 6.2L supercharged V8. Quantities include the oil filter, and a final level check must follow the manual’s filling procedure. Do not use horsepower, trim name or a similar model as a substitute for identifying the engine. Replacement filters, spark plugs and other part numbers should be confirmed by VIN. Fluid requirements differ by transmission, axle and transfer-case application; confirm the correct specification before adding or replacing a fluid.
| Engine / Version | Required Engine Oil | Oil Fill With Filter |
|---|---|---|
| 5.7L V8 | SAE 0W-20 full synthetic, MS-6395 | 7.0 qt |
| 6.4L V8 | SAE 0W-40 full synthetic, MS-12633 | 7.0 qt |
| 6.2L supercharged V8 | SAE 0W-40 full synthetic, MS-12633 | 8.3 qt |
Towing, Performance & SRT Hellcat Considerations
The 2027 manual expressly includes the 6.4L and 6.2L performance-engine maintenance plan. Both use the 6,000-mile/six-month oil limit and spark-plug replacement at 60,000 and 120,000 miles. Use this performance-engine plan separately from the 5.7L engine’s intervals. Performance-engine plans include 30,000-mile/30-month transfer-case and axle-fluid changes, 12,000-mile/12-month inspections and 90,000-mile PCV inspection. For the 5.7L, the manual lists transfer-case fluid at 30,000-mile/three-year intervals where equipped; axle-fluid changes at those checks depend on severe use. Keep the vehicle’s messages and condition checks in the service plan, even when a major mileage item is not yet due. If you notice a new leak, vibration, warning or braking change, arrange an inspection instead of waiting for the next scheduled visit.
- Identify the installed engine and drivetrain before selecting fluids.
- Ask for a condition check after off-road travel, water exposure or a suspected leak.
- Use the correct tire-rotation pattern for the installed wheel and tire sizes.
- Confirm replacement filters and spark-plug part numbers by VIN.
Severe & Special Operating Conditions
Performance-engine plans include 30,000-mile/30-month transfer-case and axle-fluid changes, 12,000-mile/12-month inspections and 90,000-mile PCV inspection. For the 5.7L, the manual lists transfer-case fluid at 30,000-mile/three-year intervals where equipped; axle-fluid changes at those checks depend on severe use. More frequent attention can be needed in demanding conditions. A condition-based oil message and a specific severe-use fluid interval serve different purposes: follow each item that applies. Discuss the operating conditions below with your advisor; do not assume every shortened interval applies to every engine or drivetrain.
- Frequent towing or heavy loads
- Repeated short trips and extended idling
- Dust, gravel roads or off-road use
- Extreme heat or cold
- Commercial, police, taxi or fleet service where named in the plan
