The 2015 Dodge Durango RT with the 5.7L Hemi uses SAE 5W-20 motor oil that meets Chrysler MS-6395 specifications, with an oil capacity of about 7 quarts including the filter.
This article explains the official oil requirements for the Durango RT, why that viscosity is recommended, and how to manage changes and maintenance for this V8 SUV.
Recommended oil and specifications
Official guidance for the Durango RT’s 5.7L Hemi centers on a single viscosity and a Mopar specification.
- Viscosity: 5W-20 engine oil
- Specification: Mopar MS-6395 (Chrysler/Dodge/Jeep oil standard)
- Oil type: Synthetic or synthetic-blend oils are acceptable as long as they meet MS-6395
- Capacity: Approximately 7 quarts (about 6.6 L) of oil with a new filter
These standards help ensure proper lubrication, engine protection, and long-term reliability under typical family-sedan and SUV driving conditions.
Maintenance intervals and tips
Intervals for changing the oil depend on driving conditions and whether the vehicle is equipped with an oil life monitor. Use the monitor or the owner’s manual to determine the exact interval.
- Normal driving: typically up to about 7,500 miles (12,000 km) between changes, or as indicated by the oil life monitor
- Severe or frequent short trips, extreme temperatures, or heavy towing: more frequent changes, commonly in the 3,000–5,000 mile (4,800–8,000 km) range
- Always verify the fill level after an oil change and use the correct filter that meets MS-6395
In practice, most Durango owners rely on the vehicle’s oil life monitoring system for the exact interval, and consult the manual for climate-specific adjustments.
Practical guidance for changing oil
When performing a change, follow these general steps and specifications to maintain reliability and warranty coverage.
- Use a 5W-20 oil that meets MS-6395
- Install a quality oil filter that meets the same specification
- Drain the old oil completely, replace the drain plug to the correct torque, and fill with approximately 7 quarts of oil
- Check for leaks and ensure the oil level is within the recommended range on the dipstick
Always refer to the owner’s manual for exact capacities and torque specifications and consider using synthetic oil for better protection and longer intervals when your driving pattern allows it.
Summary
The 2015 Durango RT’s 5.7L Hemi requires 5W-20 engine oil that meets Chrysler MS-6395, with an approximate total capacity of 7 quarts including the filter. Use either synthetic or synthetic-blend oil that conforms to MS-6395, and rely on the vehicle’s oil life monitor or manual to determine the exact change interval. Regular checks and proper filtration help keep the V8 running smoothly over the life of the vehicle.

Can I use 5W-30 instead of 5W20 in my Dodge?
Using 5W-30 instead can reduce fuel economy and impede flow throughout the engine. While using it temporarily in a pinch likely won't cause your engine lasting harm, remember that the engineers who built your engine did so with a specific viscosity oil in mind, meaning it's best to stick with it.
What oil does a 5.7 HEMI Durango take?
Blauparts recommends that any vehicle with a factory warranty use oil that specifically states it meets the factory quality specification and the proper viscosity. An example of this is the 5.7L Hemi V8 engine should use the MS-6395 oil quality specification and viscosity of SAE 0W-20.
