The RAM 1500 with a 5.7-liter Hemi typically uses SAE 5W-20 synthetic motor oil, with 5W-30 permitted in hot climates or certain model years. Always verify the exact specification in your owner’s manual or on the oil fill cap.
Oil type and specifications for the 5.7 Hemi
Details matter because oil specifications can vary by year, climate, and engine option. The 5.7 Hemi generally relies on a Mopar specification (MS-6395) and a synthetic or synthetic-blend oil that meets API SN (or newer) and ILSAC GF-5 standards. In practice, most RAM 1500 5.7 models list 5W-20 as the standard viscosity, with 5W-30 permitted in hotter climates or for specific years per the manual; the exact requirement should be confirmed for your vehicle.
Here are the common oil options you should know about:
- 5W-20 synthetic motor oil meeting Mopar MS-6395 and API SN/ILSAC GF-5 (the typical factory spec).
- 5W-30 synthetic motor oil meeting Mopar MS-6395 and API SN/ILSAC GF-5 (allowed in hot climates or as specified by the manual).
Concluding: These options cover the most typical viscosities and standards used by RAM for the 5.7 Hemi; always follow the exact guidance for your year and region from the owner’s manual.
How to confirm the exact oil requirement for your vehicle
To avoid a mismatch, confirm the correct oil by checking several sources specific to your truck:
- Consult your RAM 1500 owner’s manual for the exact viscosity and specification (MS-6395 and API/ILSAC ratings).
- Inspect the engine oil fill cap—many caps display the recommended viscosity (for example, 5W-20 or 5W-30).
- Refer to Ram’s official documentation or a VIN-specific service page to confirm the precise requirement for your year and region.
Concluding: Verifying the exact requirement ensures optimal engine protection and compliance with warranty terms, especially when climate or driving conditions differ from the standard.
Summary
In short, RAM 1500s equipped with a 5.7-liter Hemi typically require SAE 5W-20 synthetic oil (5W-30 is acceptable in certain climates or years), meeting Mopar MS-6395 along with API SN/ILSAC GF-5 or newer. Always confirm with your owner’s manual or the oil cap for your specific year and region.
