The short answer: use synthetic 5W-20 motor oil for both available engines in the 2014 Chrysler 300 (the 3.6L Pentastar V6 and the 5.7L Hemi V8).
In this article we’ll break down the official oil specification for the 2014 300, what the numbers mean, and practical guidance on oil selection, capacity, and change intervals. Always consult your owner’s manual or dealer for VIN-specific requirements.
Engine options and oil requirements
Here's a quick rundown of the two engines offered in the 2014 300 and the oil they require.
- 3.6L Pentastar V6 — SAE 5W-20 synthetic motor oil (API SN or newer, ILSAC GF-5 or newer)
- 5.7L Hemi V8 — SAE 5W-20 synthetic motor oil (API SN or newer, ILSAC GF-5 or newer)
Both engines share the same viscosity specification in the owner's manual, so a single 5W-20 synthetic oil is appropriate for either powerplant. Always verify with your manual or dealer if you have a VIN that might call for a specific variant.
Why 5W-20 and what it means
The 5W-20 designation describes a thin, cold-flow oil that improves startup protection and fuel efficiency on modern engines. For the 2014 Chrysler 300, 5W-20 synthetic oil is the standard specification to meet the engine tolerances and emission requirements common to these powertrains.
When shopping for oil, look for a full synthetic (or a high-quality synthetic blend) that meets API SN or newer and ILSAC GF-5 or newer, and be sure it is labeled as 5W-20.
Oil capacity and service intervals
Oil capacity varies by engine; knowing the approximate amount helps you plan a proper oil change. Use the owner’s manual or service manual for exact figures, but these are typical ranges:
- 3.6L V6: about 5 quarts with filter
- 5.7L Hemi V8: about 7 quarts with filter
Always install a new filter and reset the maintenance reminder as described in the manual. Follow the recommended change interval in your owner’s manual, which typically aligns with 6 months or 6,000 miles for conventional driving, or longer intervals if you use synthetic oil and your driving conditions meet those specifications.
Choosing the right oil and what to watch for
To ensure you meet the factory spec and protect your engine, consider these guidelines when selecting oil.
- Viscosity: 5W-20 is the required grade for both engines in the 2014 300.
- Oil type: Prefer full synthetic for best protection and to meet modern engine tolerances.
- Certification: Look for oils that meet API SN or newer and ILSAC GF-5 or newer on the bottle.
Using the correct oil type helps maintain warranty coverage and engine health over time. If you drive in extreme temperatures or tow heavy loads, consult the manual for any climate-specific considerations, though 5W-20 is the standard specification for the 2014 model year.
Maintenance tips and reminders
Regular oil changes are essential for long-term engine reliability. Here are quick tips to help you stay on track.
- Keep a record of oil changes and service intervals to avoid missed maintenance.
- Use a compatible oil filter rated for your engine and oil grade.
- Dispose of used oil properly at a certified recycling facility.
Sticking to the recommended oil type and change schedule helps preserve engine performance and efficiency over time.
Summary
For the 2014 Chrysler 300, the recommended oil is synthetic 5W-20 for both the 3.6L Pentastar V6 and the 5.7L Hemi V8, meeting API SN or newer and ILSAC GF-5 or newer. Always confirm the exact specification in your owner’s manual and use a high-quality synthetic oil to ensure optimal protection and fuel economy. Keep to the prescribed change intervals and proper oil capacity for your engine.
