The 5.7-liter Hemi in Dodge Charger generally uses SAE 5W-20 full-synthetic motor oil, with 5W-30 as a practical alternative in hot climates or when towing. Always verify the exact specification in your owner's manual or with a Dodge service advisor.
Understanding the oil specification
The 5.7 Hemi typically follows Mopar’s engine oil guidelines, emphasizing oils that meet the Chrysler MS-6395 specification and carry API service classifications such as SN or newer, along with ILSAC GF-5 or newer. Synthetic or synthetic-blend oils are commonly recommended for better protection and deposits control. Because exact requirements can vary by model year and market, the owner’s manual is the authoritative source.
Recommended oil viscosities and specifications
Below are the viscosities you’ll commonly see listed for the 5.7 Hemi Charger. They reflect standard factory guidance and widely available aftermarket options. Always verify year-specific guidance in the manual.
- 5W-20: Full synthetic or synthetic-blend oil meeting Mopar MS-6395, API SN or newer, and ILSAC GF-5 or newer.
- 5W-30: Full synthetic or synthetic-blend oil meeting the same specifications; used in hot climates or when the vehicle is under heavier loads or towing.
Choosing the correct viscosity supports engine protection and optimal performance. If you’re unsure, consult a dealer or a trusted mechanic who can confirm the exact specification for your vehicle’s year and trim.
Oil capacity and maintenance tips
The 5.7L Hemi typically holds about 6.5 to 7 quarts of oil with a filter, depending on the exact engine variant and service setup. For best results, use the recommended oil, replace the filter at each change, and reset any oil life monitor if equipped. Typical change intervals range from roughly 5,000–7,500 miles with conventional or synthetic-blend oils, up to about 10,000 miles with full synthetic, depending on driving conditions and the owner's manual guidance.
Both viscosity choices should meet Mopar MS-6395 and API SN or newer; climate, towing, and driving style will influence the best option. When in doubt, follow the manual and seek advice from a dealership service department.
Choosing a brand and service interval
Opt for a reputable brand that confirms MS-6395 compatibility and API SN or newer, along with ILSAC GF-5 or newer. In hot climates, frequent short trips, or heavy towing, adhere to shorter service intervals and monitor oil levels regularly to maintain engine health.
Summary
In short: for most 5.7 Hemi Chargers, SAE 5W-20 full-synthetic oil is the standard recommendation, with 5W-30 as a practical alternative in hot climates or under heavier loads. Always verify the exact specification and service interval in the owner's manual, consider climate and driving style, and follow the oil capacity guidelines to maintain engine health.
