The oil you should use depends on which engine your 2015 Dodge Charger has. In general, most engines call for synthetic oil in specific viscosity grades: 0W-20 for the 3.6L Pentastar V6, 5W-20 for the 5.7L Hemi V8, 0W-40 or 5W-40 for the 6.4L Hemi V8, and 5W-40 for the 3.0L EcoDiesel V6.
In the following sections, we break down the official recommendations by engine variant and offer practical guidance for verifying the exact specification for your car. With multiple powertrains offered in the 2015 Charger, it’s important to match the oil grade and capacity to your specific engine and climate. Always consult the owner's manual or the under-hood label for the exact grade, capacity, and change interval for your vehicle.
Engine options and oil requirements
Below is a concise guide to the official oil grades associated with each engine type found in the 2015 Charger lineup.
- 3.6L Pentastar V6 — recommended oil: 0W-20 synthetic (MOPAR or equivalent); typical capacity around 5.9 quarts with filter.
- 5.7L Hemi V8 — recommended oil: 5W-20 synthetic; typical capacity around 7 quarts with filter.
- 6.4L Hemi V8 (SRT/Scat Pack) — recommended oil: 0W-40 or 5W-40 synthetic, depending on climate/spec; typical capacity around 7–8 quarts with filter.
- 3.0L EcoDiesel V6 — recommended oil: 5W-40 full synthetic; typical capacity around 7 quarts.
These guidelines reflect the official specifications for each engine variant. Exact capacity and any climate-related adjustments are documented in the owner’s manual and on the under-hood oil-fill sticker.
How to verify the exact specification for your car
Because the 2015 Charger offered multiple engines, the precise oil grade and capacity can vary by VIN and production date. To be certain, check:
- The owner’s manual section on engine oil
- The under-hood engine oil cap or nearby label for viscosity and capacity
- Your vehicle’s VIN lookup or a dealership service bulletin if you’re unsure which engine you have
Maintenance tips and oil-change intervals
With synthetic oils, many Chargers use extended-change intervals, but this can vary by engine and driving conditions. Severe service (towing, frequent short trips, extreme temperatures, or heavy loads) may require more frequent changes. Use a proven oil filter and ensure the oil meets the appropriate specification (MOPAR or equivalent). When in doubt, follow the intervals and products recommended by Mopar for your exact engine variant.
Summary
The 2015 Charger requires different oil viscosities depending on the engine: 0W-20 for the 3.6L; 5W-20 for the 5.7L; 0W-40 or 5W-40 for the 6.4L; and 5W-40 for the EcoDiesel. Always confirm the exact specification with the owner's manual or the under-hood label for your specific engine and driving conditions, and adhere to the recommended change intervals.
