What oil does Dodge use?
In short, Dodge uses different engine oils depending on the model, year and engine. For most modern gasoline Dodge engines, the standard viscosity is 0W-20 synthetic, while diesel models such as EcoDiesel and Cummins-powered trucks typically require heavier synthetic oils like 5W-40 or 15W-40. Always verify the exact specification in the owner's manual or on the oil fill cap for your vehicle.
Dodge’s oil recommendations vary by engine family and climate, so this guide provides a practical overview and guidance on where to find the exact spec for your car or truck.
Gasoline engines: common oil viscosities by engine family
Note: The following reflects typical Dodge gasoline-engine oil recommendations. Always verify for your exact year and model.
3.6L Pentastar and related modern gasoline engines
- 0W-20 synthetic oil is the most common recommendation for many 3.6L Pentastar and other modern Dodge gasoline engines. It supports cold starts and efficiency.
- 5W-20 or 5W-30 may be specified for certain engines, climates, or older model years; always refer to the owner’s manual for the exact spec.
Conclusion: For most current Dodge gasoline engines, 0W-20 synthetic is the default choice, but always confirm for your specific year/model.
V8 Hemi family (5.7L, 6.1L, 6.2L, 6.4L, etc.)
- 0W-20 synthetic is commonly recommended for many recent Hemi-based Dodge vehicles, especially in newer Challenger, Charger, and Durango models.
- In certain climates or older configurations, 5W-20 or 5W-30 may be acceptable; verify with your manual.
Conclusion: 0W-20 is a typical default for many modern Hemi engines, but always check your exact specification for your year and model.
Diesel engines: oil requirements
Note: Diesel engines in Dodge vehicles require different oils and viscosities than gasoline engines. The EcoDiesel and Cummins-powered models use full synthetic diesel oils with different viscosity specs and API/ACEA requirements.
3.0L EcoDiesel
- 5W-40 synthetic diesel oil is commonly recommended, meeting API CJ-4/CK-4 specifications (depending on model year and regional requirements).
- Use only oils labeled for diesel engines and approved by the manufacturer; change intervals follow the manual or oil-life monitoring system.
Conclusion: EcoDiesel typically uses 5W-40 full synthetic diesel oil, but confirm the exact spec for your year/model in the manual.
6.7L Cummins (Ram heavy‑duty)
- Typical guidance is to use a diesel oil such as 15W-40 meeting API CJ-4/CK-4, with some years allowing 10W-30 in cold climates or depending on emissions equipment.
- Always follow the year-specific manual, as Cummins specifications can evolve with engine updates and emissions standards.
Conclusion: For Cummins-powered Dodges/Rams, diesel oil specs are distinct from gasoline specs and should be verified per model year and climate.
How to find the exact oil specification for your Dodge
To ensure you use the right oil for your vehicle, follow these steps and use the exact specification listed by the manufacturer.
- Consult the owner's manual for the exact viscosity (e.g., 0W-20, 5W-40) and oil specification (API, OEM approvals).
- Check the oil fill cap on the engine for the recommended viscosity code, if present.
- Look at the service interval sticker or maintenance schedule in the vehicle to confirm the recommended oil grade and change interval.
- If in doubt, contact a Dodge/ Ram dealer or certified service center with your VIN to confirm the correct oil specification for your exact year and model.
Conclusion: The best practice is to rely on the official manual and manufacturer-approved oils; variations exist by engine and year, so double-check before an oil change.
Why using the right oil matters
The right motor oil affects protection, efficiency, and emissions. Using the incorrect viscosity or an oil that doesn’t meet the required specification can compromise lubrication, fuel economy, and warranty coverage. Always use oils that meet the manufacturer’s spec and oil-change interval recommendations.
Summary
Dodge uses a range of oils depending on the engine and year. For most modern gasoline engines, 0W-20 synthetic is the default, with exceptions requiring 5W-20 or 5W-30 based on climate or model. Diesel engines, including EcoDiesel and Cummins-powered models, typically require heavier synthetic diesel oils such as 5W-40 or 15W-40 and specific API/CK-4/J-CJ-4 approvals. The exact specification must be confirmed from the owner's manual, the oil fill cap, or a dealership to account for year, model, and regional requirements. Regularly checking and following the official guidance helps maintain engine performance and warranty compliance.
