The 2013 Ram 1500 with the 5.7 L HEMI uses SAE 5W-20 engine oil that meets Mopar MS-6395 specifications. It typically takes about 7 quarts of oil with a filter, and both conventional and synthetic oils that meet MS-6395 are acceptable.
Oil type and specifications
Choosing the right oil for the 5.7L HEMI starts with an approved viscosity and factory specifications. For this model year, Mopar/MS-6395 5W-20 is the standard lubricant, designed to provide proper lubrication, fuel efficiency, and protection under normal driving conditions. In very hot climates or under severe service, some owners consider 5W-30, but you should verify this with the owner's manual or the service label under the hood.
MS-6395 and compatibility
The MS-6395 specification is Chrysler’s standardized oil spec for many of its engines. Oils labeled MS-6395 with a viscosity of 5W-20 are the safest choice for this 5.7 L HEMI. If you choose a synthetic or conventional oil, ensure it is certified to meet MS-6395 and, ideally, API SN or newer in addition to the MS-6395 requirement.
Key standards to consider when shopping for oil:
- Viscosity: 5W-20 is the standard; 5W-30 may be used only if the manual explicitly allows it for your climate and drive conditions.
- Specification: Oil must meet Mopar MS-6395; API SN or newer is typically acceptable when it accompanies MS-6395 compliance.
- Oil type: Conventional or synthetic is acceptable provided it meets MS-6395.
In short, the recommended oil for this engine is 5W-20 that meets MS-6395, with flexibility to use synthetic or conventional oils that meet the same specification.
Oil capacity and service intervals
Understanding the correct oil capacity and maintenance schedule helps ensure the engine stays properly lubricated and within warranty terms. The 5.7L HEMI in the 2013 Ram 1500 typically requires roughly 7 quarts of oil, including the filter.
- Capacity: About 7 quarts of oil, with the exact figure depending on the filter used and whether the drain plug washer is replaced.
- Oil filter: Use a quality filter that meets OEM/MS-6395 compatibility and replace it at every oil change.
- Change interval: Conventional oil is commonly changed every 3,000–5,000 miles; synthetic oil can extend to about 5,000–7,500 miles, depending on driving conditions and manufacturer recommendations.
Always follow the schedule in your owner's manual and consider driving conditions (short trips, extreme temperatures, towing) when planning oil changes.
Additional tips and considerations
If you’re unsure about the exact specification for your specific build, check the engine oil fill cap for the recommended viscosity, consult the owner’s manual, or contact a Ram dealer or certified technician. Vehicle build options or regional requirements can influence the exact recommendation.
Summary
For a 2013 Ram 1500 with a 5.7 L HEMI, use SAE 5W-20 engine oil that meets Mopar MS-6395 (synthetic or conventional). The engine holds about 7 quarts of oil with the filter. Oil changes are typically performed every 3,000–5,000 miles with conventional oil or 5,000–7,500 miles with synthetic, depending on driving conditions. Always verify the exact specification in your owner's manual or with your dealer to account for any model-year or regional variations, and ensure the oil you buy carries MS-6395 approval.
