The 2014 Ram 5.7 HEMI normally uses SAE 5W-20 full-synthetic engine oil, with about 7 quarts (6.6 liters) of capacity including the filter. An alternative 5W-30 can be used in hot climates or when towing heavy loads, per the owner's manual. Always verify the exact specification for your vehicle in the manual or with a dealer.
In this article, we break down the official recommendations for oil grade, capacity, and maintenance intervals for the 5.7 HEMI used in Ram trucks from 2014. We also offer practical tips to ensure you service the engine correctly and stay within the manufacturer’s guidelines.
Recommended oil grades and when to use them
The following options reflect the standard guidance and practical use cases for the 5.7 HEMI engine:
- 5W-20 full synthetic engine oil (recommended for normal driving in most conditions; meets Chrysler/MS-6395 and API specifications).
- 5W-30 full synthetic engine oil (allowed in very hot climates or for heavy towing/childing under severe service; still should meet Chrysler/MS-6395 and API specs).
Choosing the right grade depends on climate, load, and driving habits. Always use oil that meets the manufacturer’s specifications and consult the owner’s manual for your exact model configuration.
Oil capacity and change intervals
Key numbers to keep in mind when planning oil changes are listed below:
- Oil capacity: about 7 quarts (6.6 liters) with the filter installed.
- Normal-drives change interval: typically around every 7,500 miles (12,000 kilometers) when using synthetic oil, though always follow the vehicle’s oil life monitor and manual guidance.
- Severe-service interval: more frequent changes (commonly 3,000–5,000 miles or 5,000–8,000 kilometers) if you tow regularly, drive in extreme temperatures, or do a lot of short trips; consult the manual or dealer for guidance based on your usage.
These intervals can vary by climate, driving style, and whether your Ram is used for towing or heavy loads. Always prioritize the official maintenance schedule and the oil-life monitoring system in your vehicle.
Notes on verification and maintenance tips
To ensure you’re using the exact specification for your truck, verify with the owner’s manual and consider keeping a log of oil changes. Use a quality oil filter that meets OEM standards, and avoid over-tightening drain plugs or mixing oil grades beyond what is recommended for your model.
Summary
For the 2014 Ram 5.7 HEMI, the standard oil is 5W-20 full synthetic (about 7 quarts with filter), with 5W-30 as an acceptable alternative in hot climates or for severe towing. Always follow the manual and use oils that meet Chrysler/MS-6395 specifications. Adhering to the recommended change intervals and maintenance practices helps protect the engine and maintain performance.
