In most Ram 1500 pickups equipped with the 5.7 HEMI, the recommended oil is SAE 5W-20 synthetic, used to meet Chrysler’s MS-6395 specification. The typical oil capacity is about 7 quarts with a new filter. Always confirm the exact requirements for your year and drivetrain in the owner’s manual.
Standard oil specification for the 5.7 HEMI
This section lays out the core oil grade, specification, and capacity that apply to the majority of Ram 1500 5.7 HEMI models.
- Oil grade and viscosity: SAE 5W-20 synthetic motor oil (full synthetic preferred).
- Specification: Meets or exceeds Chrysler MS-6395; API SN or newer compliance (GF-5 or newer).
- Capacity: About 7 quarts (6.6 L) of oil, plus a new oil filter; exact capacity can vary slightly by year and engine variant.
- Oil change interval: Typically every 7,500 miles (12,000 km) under normal driving; more frequent changes (3,000–5,000 miles) for severe service or extreme conditions.
Conclusion: For most Ram 1500 5.7 HEMI owners, 5W-20 synthetic oil that meets MS-6395 is the standard choice, with roughly 7 quarts per oil change.
When a different viscosity might be used
There are situations where a different viscosity may be permitted or advisable. This section explains the nuances and where to look for guidance.
- Alternative viscosity: In some cases, 5W-30 may be acceptable if 5W-20 is not available, but this should follow the owner's manual guidance or dealer advice.
- Climate and driving conditions: In very hot climates or under heavy-load conditions, the manual may specify staying with 5W-20 or transitioning to a heavier grade only if explicitly advised.
- Model-year variations: A few years or special editions may have slightly different guidance; always verify the exact specification for your year in the manual or a dealership service bulletin.
- Brand and spec: Use oil that meets MS-6395 and API SN or newer; OEM Mopar oil and filters are common choices, but other reputable brands that meet the spec are acceptable.
Conclusion: Always verify the exact specification for your specific model year; the standard recommendation remains 5W-20 synthetic oil that meets MS-6395 in most cases.
Practical tips for selecting and maintaining oil
- Filter compatibility: Use an oil filter that fits the Ram 1500 5.7 HEMI and meets OEM specifications (Mopar or approved equivalents).
- Oil brand and quality: Choose a full synthetic oil that meets MS-6395 and API SN or newer; avoid unverified brands that do not meet the required spec.
- Record-keeping: Maintain a log of oil changes and check the oil level regularly to ensure you stay within the recommended range.
Conclusion: Adhering to the manufacturer’s recommended oil grade, specification, and change intervals helps sustain engine performance and longevity.
Bottom line for Ram 1500 5.7 HEMI oil
The core takeaway: Use SAE 5W-20 synthetic oil that meets Chrysler MS-6395, with an approximate capacity of 7 quarts per change. Confirm year-specific guidance in the owner’s manual, as updates and regional differences can alter exact requirements.
Summary
The Ram 1500 5.7 HEMI typically runs on 5W-20 synthetic oil that complies with the MS-6395 specification, with about 7 quarts required per oil change. While 5W-30 may be permissible in certain circumstances, the standard guidance is to stick with 5W-20. Always consult your vehicle’s manual for the precise specification for your model year and climate, and choose a quality oil and corresponding filter accordingly. Regularly schedule maintenance to preserve performance and engine life.
