Recommended Ram 1500 Oil Type
For most Ram 1500 gasoline engines, especially the widely used 5.7L HEMI V8, the recommended oil is:
- Viscosity: 5W-20
- Type: Full synthetic
- Specification: Chrysler MS-6395
This specification is essential because the HEMI engine uses a fuel-saving system called Multi-Displacement System (MDS). This system relies on proper oil flow and pressure to activate and deactivate cylinders. Using the wrong oil can affect performance and even cause long-term engine issues.
Other engine options may differ slightly:
- 3.6L V6: 5W-20 or 0W-20 (newer models)
- EcoDiesel: 5W-30 or 5W-40 diesel-specific oil
If you’re unsure, always check your owner’s manual. However, for most Ram 1500 trucks, 5W-20 full synthetic oil is the safest and most widely recommended choice.

Why Full Synthetic Oil Is Recommended
Full synthetic oil is designed for modern engines and offers several advantages over conventional oil:
- Better resistance to heat and breakdown

- Cleaner engine with fewer deposits
- Longer oil change intervals
Modern Ram engines are built with tight tolerances, making synthetic oil the best option for consistent lubrication and durability.
How to Choose the Right Oil
When selecting oil for your Ram 1500, keep these factors in mind:
1. Follow the recommended viscosity
Stick to 5W-20 unless your manual specifies otherwise.
2. Check certifications
Ensure the oil meets Chrysler MS-6395 requirements.
3. Consider driving conditions
