What type of oil does a 5.7 Hemi Challenger take?
The 5.7L Hemi in a Challenger typically calls for a 5W-20 synthetic oil that meets Chrysler’s MS-6395 specification, with an approximate total oil capacity of about 7 quarts (including the filter). Always verify the exact requirements in your owner’s manual for your model year and climate, as some revisions or conditions may allow 5W-30.
Understanding the oil needs of a 5.7 Hemi Challenger involves matching viscosity, certification, and the engine’s maintenance needs to the specifications set by the manufacturer. The following guide summarizes the standard recommendations and practical considerations you should know as a Challenger owner or prospective buyer.
Oil type and specifications
Below is a concise overview of the key specifications to look for when selecting oil for a 5.7 Hemi Challenger.
- Viscosity: The default recommendation is 5W-20 for most climates and model years. In very hot climates or under certain conditions, 5W-30 may be acceptable per the manual, but 5W-20 remains the standard default.
- Certification/spec: Use oil that meets Chrysler MS-6395. API SN (or newer) and ILSAC GF-5 (or newer) compatibility are commonly accepted as long as the MS-6395 requirement is satisfied.
- Oil type: Synthetic or synthetic-blend oils are acceptable; many owners prefer full synthetic for better protection and longer drain intervals.
- Brand and packaging: Look for the MS-6395 label on the container or product briefing from reputable brands to ensure compatibility with the engine’s tolerances and warranty requirements.
Conclusion: Following these specifications helps ensure proper lubrication, fuel efficiency, and engine longevity for the 5.7 Hemi Challenger.
Capacity and maintenance intervals
Understanding how much oil the engine holds and when to change it is essential for reliable operation and warranty compliance.
- Oil capacity: Approximately 7 quarts (about 6.5–7 quarts depending on the oil filter and engine variant).
- Change interval: With synthetic oil, typical change intervals range from about 5,000–7,500 miles under normal driving conditions; severe service or extreme driving conditions may require more frequent changes. Always follow the interval listed in your owner's manual.
- Oil filter: Replace the oil filter with every oil change to maintain filtration efficiency and oil flow.
- Checking the level: After the engine has cooled, use the dipstick to verify the oil level between the markings; add as needed to reach the correct level.
Conclusion: Accurate capacity and regular oil changes are crucial for maintaining peak performance and protecting the 5.7 Hemi’s long-term reliability.
Summary
For most Dodge Challenger 5.7L Hemi engines, use 5W-20 synthetic oil that meets Chrysler MS-6395, with an approximate capacity of 7 quarts including the filter. Verify the exact specification and interval in your owner’s manual, as climate and model year can influence the recommended viscosity and change schedule. Regular maintenance—using the right oil and changing it on time—helps preserve engine performance and warranty coverage.
