The RAM 1500 with a 5.7 HEMI most commonly uses SAE 5W-20 synthetic engine oil, with a total capacity of about 7 quarts (approximately 6.6 liters) including the filter. Always verify the exact specification in your vehicle’s owner’s manual for your model year, as recommendations can vary slightly over time or with equipment like towing packages or cold-weather options.
Baseline oil specification for the 5.7 HEMI
Understanding the standard specification helps ensure you’re using oil that protects the engine and maintains warranty coverage. The 5.7 HEMI generally requires an oil that meets Mopar’s MS-6395 specification and is API SN or newer, with a viscosity of 5W-20 as the default. In certain climates or duty scenarios, your manual may allow an alternative viscosity such as 5W-30, but this should only be used if explicitly approved by the manual or a dealer.
Here are the key points to keep in mind before reviewing the specifics:
- Default viscosity: 5W-20 synthetic oil that meets MS-6395 (API SN or newer).
- Alternative (when approved): 5W-30 synthetic oil may be permitted in hot climates or under heavy towing/loads, per the owner’s manual.
- Always confirm year-by-year requirements in the official manual or with a dealer, as specifications can change over time.
In summary, the standard setup is 5W-20 synthetic oil meeting Mopar’s MS-6395 with about 7 quarts capacity; deviations require explicit approval in your manual.
Oil capacity and maintenance intervals
Knowing the capacity and service schedule helps plan oil changes without over- or under-filling. The RAM 1500 5.7 HEMI holds roughly 7 quarts of oil with the filter installed. Maintenance intervals are driven by the owner’s manual and, in modern vehicles, by an oil life monitoring system which can adjust based on driving conditions and engine stress.
Before you review the maintenance details, keep these notes in mind:
- Oil capacity: about 7 quarts (roughly 6.6 liters) with a filter.
- Change intervals: follow the vehicle’s maintenance schedule or oil life monitor; synthetic oil often allows longer intervals than conventional oil, but you should follow the manual’s guidance for your year and configuration.
- Severe driving conditions (extreme heat, frequent towing, short trips) typically require more frequent changes per the owner’s manual.
In short, plan around a 7-quart fill and rely on the maintenance schedule in your manual or the oil life monitor to determine when to change the oil.
Practical tips for buying and applying oil
Choosing the right oil involves matching the spec, viscosity, and quality to your RAM’s needs. The following guidance helps ensure you pick oil that protects the engine and maintains efficiency and warranty coverage.
- Use oil that meets Mopar MS-6395 and API SN (or newer) with a viscosity of 5W-20 for the default configuration.
- If your manual allows it, 5W-30 synthetic may be used in hot climates or heavy towing applications; always verify first.
- Prefer synthetic or high-quality synthetic-blend oils from reputable brands rather than conventional oils for extended intervals and better protection.
- Pair the oil with an OEM-recommended oil filter and change the filter with every oil change.
These steps help ensure proper lubrication, engine longevity, and compliance with maintenance schedules for your specific year and trim level.
Summary
For most RAM 1500s powered by the 5.7 HEMI, the standard oil is SAE 5W-20 synthetic, meeting Mopar MS-6395, with an approximate capacity of 7 quarts including the filter. Always consult your owner’s manual for your exact year and configuration, since some climates or towing setups may permit a different viscosity such as 5W-30 when explicitly approved. Use high-quality synthetic oil and the correct filter, and rely on the vehicle’s oil life monitor or the manual’s maintenance schedule to determine oil-change intervals.
