In most cases, the 5.7 L HEMI uses 5W-20 full-synthetic oil that meets Chrysler’s MS-6395 specification, with an overall fill capacity of roughly 6.5–7 quarts. Always verify the exact requirement for your year and climate in the owner’s manual or with a dealer.
Official oil specification
The 5.7 L HEMI is designed to run on a light-viscosity, fully synthetic oil that meets Chrysler MS-6395. This ensures proper lubrication, fuel economy, and engine protection across a range of operating conditions.
- Viscosity: 5W-20 is the standard grade for most 5.7L HEMI applications.
- Oil type: Full-synthetic or synthetic-blend oil that meets Chrysler MS-6395 is recommended.
- Certification: Look for API SP or newer, with ILSAC GF-6 compatibility where indicated.
- Capacity: Approximately 6.5–7 quarts (with filter replacement); exact capacity can vary by year and configuration.
Concluding: Use a 5W-20 full-synthetic oil that meets MS-6395 for typical 5.7L HEMI engines, and confirm your specific year and climate in the owner’s manual or with a dealer.
Climate and model-year variations
While 5W-20 MS-6395-compliant oil covers the majority of recent 5.7 L HEMI vehicles, some older models or extreme climates may have alternate allowances documented in the manual. When in doubt, consult the owner’s manual or contact a dealer to confirm the correct viscosity and specification for your vehicle.
- Default recommendation: 5W-20 synthetic oil meeting MS-6395 for most modern 5.7L HEMIs.
- Possible alternatives: 5W-30 may be permitted in hot climates or under certain towing conditions as specified by the owner’s manual.
- Compliance: Always choose oil that explicitly states MS-6395 compliance and API SP or newer.
- Verification: Check the under-hood oil specification label or the owner’s manual for your exact year/model.
How to confirm your vehicle’s exact requirement: always verify with the manual or a dealership, since year-by-year differences exist even within the same engine family.
How to confirm the correct oil for your vehicle
To ensure you’re using the right oil, follow these steps:
- Consult the vehicle’s owner’s manual for the recommended viscosity (typically 5W-20) and the MS-6395 requirement.
- Check under-hood labels near the oil fill cap or dipstick for any stated specifications.
- Choose an oil that explicitly meets Chrysler MS-6395 and is API SP or newer; GF-6 compatibility is acceptable in current formulations.
- Fill with the approximate capacity (about 6.5–7 quarts for a full change) and recheck the level after running the engine and cooling.
Note: Always replace the oil filter during a change and follow the service interval recommended by the manufacturer.
Summary
The standard for most 5.7 L HEMI engines is 5W-20 synthetic oil meeting Chrysler MS-6395, with an approximate fill of 6.5–7 quarts. Verify the exact requirements for your model year and climate in the owner’s manual or with a dealer, and look for oil that is API SP or newer and GF-6 compatible where applicable. Adhering to the specified oil ensures optimal lubrication, performance, and warranty compliance.
