The Ram 1500 with a 5.7 V8 typically uses synthetic motor oil in the 0W-20 or 5W-20 range, and it must meet Chrysler’s MS-6395 specification. The exact grade depends on the model year and climate, so always verify with your owner's manual or the oil cap on the engine.
Overview of recommended oil grades
Below are the common options you’ll encounter for the 5.7 Hemi, with the emphasis that the final choice should align with your specific vehicle year and operating conditions.
- 0W-20 synthetic oil that meets FCA MS-6395 (preferred in many modern Ram 1500 models, particularly in cold or variable climates).
- 5W-20 synthetic oil that meets FCA MS-6395 (an acceptable alternative when 0W-20 is not available or per year/climate indications in your manual).
Regardless of the choice, ensure the oil is synthetic and meets MS-6395. Adhere to the service intervals in your owner's manual, and adjust for severe driving conditions, towing, or extreme temperatures.
Specifications to look for when shopping for oil
When buying oil, prioritize compatibility with the Ram’s requirements and the engine’s specifications. Use the following guidelines to choose the right product.
- MS-6395 compatibility (Chrysler/Fiat FCA specification) is the primary requirement for the 5.7 Hemi in Ram 1500.
- Viscosity options typically include 0W-20 or 5W-20 synthetic; your manual will specify the recommended grade for your climate and year.
- API quality rating (such as SN, SP) and industry standards like ILSAC GF-6 are common, but the key is that the oil meets MS-6395.
Always follow the oil-change schedule in your manual and consider more frequent changes for severe service, extreme heat or cold, or heavy towing.
Summary
In short, the Ram 1500 with a 5.7 V8 generally requires synthetic oil in the 0W-20 or 5W-20 range that meets Chrysler’s MS-6395 specification. Confirm the exact grade for your year and climate by consulting the owner's manual or the engine oil cap, and choose a high-quality synthetic oil accordingly.
