The 2020 Chrysler 300 with the 3.6-liter V6 typically requires 5.5 quarts of engine oil when performing an oil change, including the filter.
For most owners, the recommended oil is 5W-20 synthetic, and the capacity refers to the amount needed to fill the engine to the proper level with a new filter installed. Always verify this specification against your owner’s manual or with a dealer, as regional variations can occur and some service guides list the value as "with filter."
Oil capacity and specifications
Key facts about the 3.6 L engine’s oil capacity and grade are summarized below.
- Engine oil capacity (with filter): 5.5 quarts
- Recommended viscosity: 5W-20
- Recommended oil type: Synthetic (full synthetic preferred)
- Filter: Replace with OEM Mopar or equivalent at each oil change
When you perform an oil change, start with the full 5.5 quarts to reach the proper level after the new filter is installed. Then, run the engine, check for leaks, and verify the oil level on the dipstick.
Notes on accuracy and variations
Some sources may list slightly different numbers (for example, 5.9 quarts) depending on whether the filter is replaced, the exact filter size, or whether the measurement is taken with the engine hot or cold. Always rely on the official specification in the owner’s manual for your exact vehicle configuration.
DIY oil change checklist
If you’re planning to change the oil yourself, use these guidelines to hit the capacity accurately and maintain engine health.
- Gather supplies: 5W-20 synthetic oil, 5.5 quarts total, new oil filter (OEM or equivalent), drain pan, funnel, sockets, jack stands or a ramp, gloves, and rags.
- Prepare the vehicle: warm the engine briefly to loosen oil, then lift and secure the car safely.
- Drain old oil: remove the drain plug and let the oil fully drain from the pan, then remove the old filter and let any remaining oil drip away.
- Install new filter: screw on the new filter by hand until snug, plus a final gentle turn as specified by the filter manufacturer.
- Add new oil: pour in 5.5 quarts of 5W-20 synthetic using a funnel, then check for level.
- Check and finalize: start the engine, look for leaks, run for a few minutes, turn off, and recheck the dipstick. Add small amounts if needed to reach the full mark.
- Reset maintenance indicators: if your vehicle has a service light for oil changes, reset it per the owner’s manual.
Always dispose of used oil and filters responsibly at an approved recycling facility, and confirm the oil level before driving.
