The short answer: use 5W-20 motor oil that meets Chrysler MS-6395 specifications (API SN) for the 2012 Dodge Avenger. The typical oil capacity is about five to six quarts depending on the engine, with a new filter included.
In 2012, the Avenger was offered with two engines—the 2.4-liter Tigershark inline-four and the 3.6-liter Pentastar V6. Both generally require 5W-20 motor oil that meets Chrysler’s MS-6395 standard, with synthetic blend or full synthetic options. Climate, driving conditions, and model variations can affect the exact specification, so always verify in the owner's manual or on the oil fill cap for your specific vehicle.

Maintenance tips and buying guidance
To keep the engine healthy and running smoothly, consider these practical notes while shopping for oil or planning a change.
- Choose a 5W-20 oil that meets Chrysler MS-6395 (API SN) specification; synthetic blends are acceptable and widely used.
- Prefer synthetic or synthetic-blend oil for better high/low-temperature performance and longer intervals, depending on driving conditions.
- Always replace the oil filter during changes and use the recommended capacity for your engine variant; overfilling can cause issues.
Routine maintenance, plus using the correct oil grade, helps preserve engine longevity and fuel efficiency. If you’re ever unsure about the exact specification for your VIN, contact a Dodge dealership or reference the owner’s manual.
