For most Chrysler 300 models, the recommended oil is a full-synthetic 5W-20 that meets Chrysler’s MS-6395 specification. However, exact grade and capacity can vary by engine and year, so always verify with your owner's manual or the dealer.
The Chrysler 300 lineup has spanned multiple generations and engines, including the 3.6L Pentastar V6 and various Hemi V8s. Driving conditions, climate, and maintenance history can influence the recommended viscosity and change interval. This article explains the standard guidance and how to confirm the correct oil for your specific car.
Oil specifications for the Chrysler 300
Here is a quick reference to the most common oil specifications you’ll encounter on Chrysler 300 models. Always confirm the exact grade for your engine year and climate.
- Viscosity and type: Most modern Chrysler 300 engines use a full-synthetic oil with a viscosity of 5W-20. This grade provides good cold-start performance and modern engine protection.
- Alternative viscosities: In some years or climates, 0W-20 or 5W-30 may be permitted or recommended. Always check the owner’s manual, engine oil cap, or service label for the precise specification.
- Oil specification: Use oil that meets Chrysler MS-6395. Oils that meet this specification are formulated to work with the engine tolerances and oil-life monitoring systems in these vehicles.
- Capacity: Roughly 5 quarts for the 3.6L Pentastar engine; for V8 variants such as the Hemi, capacity is typically higher (approximately 6–7 quarts, depending on exact variant and filter). Always confirm the exact capacity in the manual or by VIN.
In practice, starting with a 5W-20 full synthetic that meets MS-6395 is a reliable baseline for most Chrysler 300 models. If you live in extreme heat or cold, or you drive under severe conditions, your manual may specify a different viscosity or oil type.
Confirming the right oil for your exact car
To ensure you’re using the correct oil for your particular Chrysler 300, follow these steps. This will help you avoid compatibility issues and preserve warranty coverage.
- Check the owner’s manual for the exact oil grade, specification (MS-6395), and capacity for your engine and model year.
- Inspect the oil fill cap on the engine and any labels on the underside of the hood or engine bay for the recommended viscosity (for example, SAE 5W-20).
- Look at the driver’s door jamb service sticker or the vehicle information label for the recommended oil specification and capacity.
- Visit the official Mopar Owner’s Site or contact your local dealership with your VIN to confirm the exact spec for your car.
- If in doubt, ask a trained technician or the service department to verify the correct oil type and capacity for your engine variant.
Following these steps helps ensure you’re using the correct oil, maintaining engine performance, and protecting warranty coverage.
Summary
Bottom line: for most Chrysler 300 models, use a full-synthetic 5W-20 oil that meets MS-6395. Always verify the exact grade and capacity for your specific year and engine by consulting the owner's manual, oil cap, vehicle labels, or with a dealer. Adhering to the correct specification supports engine longevity, efficient performance, and proper oil-life monitoring.
