It takes about 6 quarts (5.7 liters) of engine oil when you replace the filter, and about 5 quarts (4.7 liters) if you don’t replace the filter. Always confirm the exact amount using the dipstick after adding oil and consult the owner’s manual for the specific spec for your vehicle.
The 2015 Chrysler 300 offers a 3.6-liter V6 (Pentastar) as the standard engine. This article explains the official oil capacity for that engine, how the figure changes with or without a new filter, and practical guidance on oil type and maintenance to keep the car running smoothly.
Oil capacity for the 2015 Chrysler 300 V6
The following figures reflect the typical capacity for the 3.6L V6 when a new filter is installed. Exact amounts can vary slightly depending on the filter model and service procedures.
- With the oil filter installed: 6.0 quarts (5.7 liters).
- Without the oil filter: 5.0 quarts (4.7 liters).
These values assume a standard drain and a properly installed filter. If you’re reusing an older filter or performing a different drain procedure, the total may differ slightly.
Oil type and change guidance
Choosing the right oil and following a consistent maintenance schedule is essential for the 3.6L Pentastar engine in the 2015 Chrysler 300. The manual typically calls for a high-quality synthetic oil, most commonly 5W-20, though climate and driving conditions can influence the exact viscosity recommendation. Some hot-climate applications may use 5W-30 if specified by the manual.
- Use a full synthetic motor oil meeting API and ILSAC standards (e.g., API SP or SN, ILSAC GF-6 as applicable).
- Refer to the owner's manual for the exact viscosity specification, with 5W-20 being common for many markets and scenarios; verify for your region.
- Follow the recommended oil-change interval based on driving conditions and oil quality (often 5,000–7,500 miles with synthetic oil, or as stated in the manual).
Concluding note: Adhering to the recommended oil grade and change interval helps maximize engine longevity and performance for the 2015 Chrysler 300’s V6, and always double-check the dipstick after filling to ensure correct oil level.
Summary
For the 2015 Chrysler 300 with the 3.6L V6, plan to use about 6 quarts of oil with a new filter (5.7 liters), or 5 quarts if not replacing the filter. Use the oil viscosity specified in the manual (typically 5W-20) and follow the manufacturer’s maintenance schedule to keep the engine in good condition. Always verify the level with the dipstick after an oil change.
