Use 0W-20 synthetic motor oil that meets Chrysler MS-6395 specification; the engine’s oil capacity is about 5.9 quarts with a filter.
Oil type and specifications
To protect the 3.6L Pentastar V6 that powers the 2018 Grand Caravan, select a full-synthetic 0W-20 oil that meets Chrysler MS-6395 and API SN (or newer) standards. This combination is widely supported by major brands and is the recommended grade for this engine.
What to look for when shopping for oil:
- Viscosity: 0W-20
- Type: Full synthetic motor oil
- Specification: Must meet Chrysler MS-6395
- Standards: API SN or newer (e.g., API SP or newer)
- Capacity: About 5.9 quarts (5.6 liters) with a new filter
In short, pick a 0W-20 full-synthetic oil that satisfies MS-6395 and API requirements, and plan for roughly 5.9 quarts per oil change depending on whether you replace the filter.
Oil capacity and maintenance intervals
Knowing the oil capacity and how often to change it helps keep the Grand Caravan running smoothly. For normal driving, using 0W-20 synthetic oil, the change interval is typically guided by the vehicle’s oil life monitor, with a practical target around 7,500 miles under many conditions. Always follow the owner’s manual and the oil-life monitor for the exact interval, especially if your driving is more demanding.
Guidelines for scheduling changes:
- Normal driving: Change oil every 7,500 miles (12,000 km) or per the oil-life monitor, whichever comes first.
- Severe service: In conditions such as frequent towing, extreme heat, or lots of short trips, change more often and rely on the oil-life monitor for indicator timing.
Conclusion: Always follow the oil-life monitor and the owner's manual for the exact interval, ensure a fresh oil filter is installed at every change, and dispose of used oil according to local regulations.
Summary
For a 2018 Dodge Grand Caravan, the recommended oil is 0W-20 synthetic motor oil that meets Chrysler MS-6395, with an approximate capacity of 5.9 quarts with a filter. Change intervals are typically every 7,500 miles or 12 months under normal driving, guided by the oil-life monitor, with more frequent changes under severe service conditions. Always consult the owner’s manual for your specific vehicle configuration.
