The 2.4 L Dodge Avenger typically requires 5W-20 motor oil that meets Chrysler MS-6395, in either synthetic-blend or full-synthetic form. Use API SN or newer and ILSAC GF-5 or newer. Always verify the exact specification for your model year and climate by checking the owner's manual or the oil filler cap.
This article explains the standard oil grade for the 2.4 L engine used in many Avenger models, how to confirm the correct viscosity for your car, and practical steps to ensure you’re using the right oil for your year and region.
Recommended oil grade and specification
Below are the standard recommendations that apply to most Dodge Avenger 2.4 L engines. Always confirm with your manual if your car has a different requirement due to year, market, or warranty terms.
- Viscosity: 5W-20 is the typical requirement for the 2.4 L engine.
- Oil type: Synthetic-blend or full synthetic oil is acceptable.
- Specification: Must meet Chrysler MS-6395; compatible with API SN or newer and ILSAC GF-5 or newer.
- Alternates: Some climates or specific year models may allow 5W-30 if explicitly stated in the owner's manual; verify before using.
In practice, many owners opt for a 5W-20 synthetic-blend that meets MS-6395 for normal driving and warranty compliance. Using a viscosity outside the recommended range can affect protection and fuel economy.
Model-year variations and climate notes
Engine specs can vary by year and market. While the 2.4 L Tigershark used in earlier Avengers generally follows the 5W-20/MS-6395 guideline, some later or market-specific iterations may reference updated approvals or alternative viscosities. Always consult the owner's manual or a dealer with your VIN to confirm the exact requirement for your vehicle.
How to determine the exact oil for your car
Use these checks to confirm the right oil for your exact vehicle:
- Check the owner's manual section on engine oil for viscosity grade and specifications (MS-6395; API SN or newer; ILSAC GF-5 or newer).
- Look at the engine oil filler cap; it often indicates the recommended viscosity (for example, 5W-20).
- Identify your model year and market, since some production years may have updated approvals or allowances.
- When in doubt, contact a dealer or certified mechanic and reference your VIN to confirm the exact specification.
Following these steps helps ensure you select an oil that protects the engine and aligns with warranty terms.
Summary
The Dodge Avenger’s 2.4 L engine most commonly uses 5W-20 oil that meets Chrysler MS-6395, in either synthetic-blend or full synthetic form, with API SN or newer and ILSAC GF-5 or newer. Always verify the precise requirement for your year and region in the owner’s manual or via your VIN, and use the recommended viscosity to maintain engine protection and efficiency.
