The 2017 Ram Rebel with a 5.7 HEMI uses synthetic 5W-20 motor oil that meets Mopar MS-6395; if 5W-20 isn’t available, 5W-30 can be used as an acceptable alternative in certain conditions. Always verify with the owner’s manual or a Ram dealer.
The Rebel’s 5.7 HEMI is a V8 that requires a specific oil specification to protect the engine’s tolerances and features such as variable valve timing. This article outlines the official grade and specification, the engine’s oil capacity, and practical maintenance tips.
Oil grade and specification
Key details to guide your selection and shopping. Mopar's MS-6395 spec is the standard benchmark for Chrysler, Dodge and Ram engines from this era, and it aligns with API SN or newer categories.
- Recommended grade and spec: 5W-20 synthetic engine oil that meets Mopar MS-6395 and API SN (or newer). Fully synthetic is preferred for this engine and climate ranges.
- Capacity: Approximately 7 quarts (6.6 liters) of oil, plus one new oil filter during a typical oil change.
- Alternative grade: 5W-30 can be used if 5W-20 is not readily available or under certain conditions such as very hot climates or when towing heavy loads; always consult the owner's manual if in doubt.
- Oil change interval guidance: Follow the vehicle’s Oil Life Monitoring System; typical intervals range up to around 7,500 miles under normal driving, with more frequent changes under severe conditions or towing.
Concluding: The default choice for most 2017 Ram Rebels is synthetic 5W-20 meeting Mopar MS-6395; 5W-30 is an acceptable fallback in specific situations. Always verify with the manual or a dealer.
Maintenance and verification
To keep the 5.7 HEMI healthy, use the dipstick to confirm the correct oil level after filling, and reset the vehicle’s oil life monitor after service. Use a trusted shop or follow the owner's manual for the service intervals.
How to check the oil level
Park on level ground, engine off and cool, pull the dipstick, wipe, reinsert, and pull again to read the level. The oil should be between the "min" and "max" marks. If it's low, add small amounts of oil until the level is correct while checking for leaks.
When to change the oil
Most owners will see intervals around 7,500 miles or 6 months for synthetic oil, but the Ram’s Oil Life Monitor can suggest different intervals based on driving conditions. For heavy towing, frequent short trips, or extreme climates, more frequent changes are advised.
Summary
The 2017 Ram Rebel with a 5.7 HEMI prefers synthetic 5W-20 oil that meets Mopar MS-6395 (API SN or newer). If 5W-20 is unavailable, 5W-30 is an acceptable alternative in certain conditions. The engine holds roughly 7 quarts of oil with a filter, and maintenance should follow the vehicle’s oil life monitor and manual guidelines. Always confirm the exact specification in your owner’s manual or with a Ram dealer.
