The short answer: use synthetic 5W-20 oil that meets Chrysler’s MS6395 specification, and plan to fill about 7 quarts (including the filter) during an oil change.
For owners of the 2016 Ram 1500, equipped with the 5.7-liter HEMI V8, choosing the right engine oil is essential for performance, fuel efficiency, and long-term reliability. This article outlines the official recommendations, practical considerations, and how to source the correct product to keep the HEMI running smoothly.
Official recommendations
Understanding the manufacturer’s guidance helps you select the correct viscosity, certification, and capacity for routine maintenance.
Viscosity, certification, and capacity at a glance
- Viscosity: 5W-20 synthetic oil is the primary recommendation for the 5.7 HEMI in the 2016 Ram 1500.
- Certification/spec: Oil should meet Chrysler MS6395 specification and be API SN (or newer) compliant.
- Capacity: Roughly 7 quarts of oil are required per oil-change interval, including a new oil filter.
- Dexos status: Dexos1 certification is not required; oils meeting MS6395 (and API SN or newer) are suitable.
Conforming to these specifications helps ensure optimal lubrication, engine protection, and warranty compliance. Always verify the exact requirements in your vehicle’s owner’s manual or with a dealer if you’re unsure.
Oil as part of the maintenance plan
Beyond viscosity and certification, practical notes matter for everyday use and long-term reliability.
- Branding choice: Reputable brands offering MS6395-certified 5W-20 synthetic oils are widely available. OEM-approved Mopar lubricants are another option.
- Replacement intervals: Follow the maintenance schedule in the owner’s manual, which reflects driving conditions and climate. Synthetic oils typically enable longer intervals than conventional oils, but conditions such as frequent short trips, towing, or extreme temperatures may necessitate shorter drains.
- Filter: Use a genuine or OEM-equivalent oil filter during changes to ensure proper filtration and fit.
- Quality indicators: Look for viscosity and certification labels on the oil container (MS6395 and API SN or newer) to confirm compatibility.
These practices help maintain oil pressure, reduce wear, and maximize the life of the 5.7 HEMI under a variety of driving scenarios.
Additional context and climate considerations
While the standard guidance calls for 5W-20 synthetic oil, climatic conditions and driving patterns can influence the choice. In some very hot climates or under severe-duty use, some owners and service advisors may consider alternatives, but the official recommendation remains 5W-20 with MS6395 certification for the 2016 Ram 1500 5.7 HEMI. When in doubt, consult your local Ram dealership or reference your owner’s manual for region-specific guidance.
Summary
For a 2016 Ram 1500 with a 5.7 HEMI, the recommended oil is synthetic 5W-20 meeting Chrysler MS6395 specification, with about 7 quarts needed per change (including the filter). The oil should be API SN or newer, and Dexos1 certification is not mandatory. Adhering to these specs supports engine protection, performance, and warranty compliance, while allowing you to choose a reputable brand or Mopar-approved option. Always confirm the exact requirement in your owner’s manual or with a dealer to ensure compatibility with your vehicle’s configuration and local conditions.
