The 2011 Dodge Nitro generally uses SAE 5W-20 engine oil as the default grade; 5W-30 is acceptable in hot climates or under severe service. The engine oil capacity is roughly 5.5 quarts with filter. Always confirm with the owner's manual or under-hood label.
In 2011, the Nitro’s standard engine was the 3.7-liter V6. Oil specifications are provided by Mopar: API service category SM or newer, and viscosity guidelines vary by climate. For best results, use either a synthetic blend or full synthetic that meets the API/Ilsac specs.
Recommended oil viscosities for the 2011 Nitro
These options cover common climate and service conditions. Always verify with the manual or the under-hood sticker.
- 5W-20: Mopar-approved engine oil (API SM or newer), compatible with most daily driving conditions; synthetic blend recommended; engine oil capacity about 5.5 quarts with filter.
- 5W-30: Acceptable in hot climates or under severe service; same API spec; same capacity; ensures better high-temperature lubrication.
Using the recommended viscosity helps ensure proper lubrication, cold starts, and fuel economy. If in doubt, default to 5W-20 and consult the manual.
Oil capacity and change interval
Oil capacity and service intervals vary by engine and driving conditions. The Nitro's engine oil capacity is around 5.5 quarts with filter for the 3.7L V6. Real-world intervals depend on driving style and climate.
