What kind of oil do I put in my Dodge Avenger?
For most Dodge Avengers from the 2007–2014 era, you’ll typically use a synthetic or synthetic-blend engine oil with a viscosity of 5W-20, with 5W-30 as an acceptable alternative in hot climates or if your manual specifies it. Always verify the exact specification for your engine in the owner’s manual or on the under-hood oil label.
Know which engine your Avenger has
The Dodge Avenger was offered with several engine options over its production years. The oil you use depends on the specific engine your car has. To be sure, locate the engine code (often on the valve cover) or check the owner’s manual, the service sticker in the engine bay, or the VIN decoding guide for your model year. Climate and driving conditions can also influence your choice.
Oil recommendations by engine
Below is a concise guide to the typical oil grades used in common Avenger powertrains. Always confirm with the official manual for your exact engine and year.
2.4L World Gas Engine — Common in many Avengers of this era. Typically uses 5W-20 as the standard viscosity; 5W-30 is acceptable in hotter climates or if your manual specifies it. Use a synthetic or synthetic-blend oil that meets API SN (or newer) and ILSAC GF-5 (or GF-6) certification.
3.5L V6 — Found in some trims or years. Often recommended to use 5W-30; synthetic or synthetic-blend formulations are acceptable, and the oil should meet API SN (or newer) and ILSAC GF-5/GF-6 standards.
2.7L V6 — Present in earlier configurations. Typically calls for 5W-30; synthetic or synthetic-blend options that meet API SN (or newer) and ILSAC GF-5/GF-6 are suitable.
Note: Engine-specific requirements can vary by year and market. If your dashboard oil life monitor is present, follow its guidance, and when in doubt, reference your owner’s manual or the under-hood oil fill label for the exact specification.
Choosing between conventional and synthetic
Oil type can impact protection, fuel economy, and intervals between changes. Synthetic oils generally offer better high-temperature stability and engine protection, especially in extremes of heat or cold, and often allow longer change intervals when combined with modern monitoring systems.
- Synthetic or synthetic-blend oil — Typically recommended for modern Avenger engines; longer service intervals and improved protection.
- Conventional oil — A less expensive option; may require more frequent changes but can be acceptable for older maintenance schedules or budget constraints.
Regardless of choice, ensure the oil meets the car’s required certification (API SN or newer, ILSAC GF-5 or GF-6) and the viscosity specified for your engine and climate in the owner’s manual.
How often to change the oil
Oil-change intervals depend on the oil type you use and how you drive. Use the vehicle’s oil life monitor if equipped, and follow local conditions. General guidance:
- Synthetic oil — commonly around 7,500 miles (12,000 km) or roughly 12 months, whichever comes first, though some drivers opt for sooner intervals.
- Conventional oil — typically 3,000–5,000 miles (5,000–8,000 km) or 6–12 months, depending on conditions.
- Follow the OEM’s recommendations and reset the oil life monitor after each change.
In all cases, if you notice unusual engine noises, burning oil smells, or a high oil level indication, service should be performed sooner rather than later.
What to check before an oil change
Before you drain and replace oil, verify:
- Your exact engine code and model year (to confirm the correct viscosity and certification).
- The oil’s certification (API SN or newer, ILSAC GF-5 or GF-6).
- Whether your climate or driving style warrants a different viscosity within the recommended range.
Always use a filter from a reputable brand and ensure the drain plug, gasket, and seals are in good condition during the service.
Summary
The Dodge Avenger typically uses 5W-20 synthetic or synthetic-blend oil as the standard, with 5W-30 as a common alternative in hotter climates or when specified by the manual. Engine choice (2.4L, 3.5L, or 2.7L) and climate influence the exact specification. Verify with your owner’s manual or the under-hood label, and choose an oil that meets API SN or newer and ILSAC GF-5/GF-6 standards. Follow recommended change intervals and maintenance, and consider synthetic oil for longer intervals and stronger protection.
