The 2012 Chrysler 3.6L engine generally requires 5W-20 full synthetic motor oil that meets Chrysler MS-6395 specifications, with an approximate capacity of 5.9 quarts plus a new filter. Always check your owner's manual or the under-hood label for the exact grade and capacity for your vehicle.
Oil specifications for the 3.6L Pentastar in 2012 models
Below are the core oil grade, type, and capacity guidelines that apply to most 2012 Chrysler 3.6L engines across compatible models (Chrysler 300, Charger, Challenger, Jeep Grand Cherokee, and others). Always use the grade and spec recommended for your specific vehicle.
- Recommended viscosity and oil type: 5W-20 full synthetic motor oil (or synthetic blend) that meets API SN or higher and Chrysler MS-6395 specification.
- Primary specification: API SN (or newer) / ILSAC GF-5 or newer; Chrysler MS-6395 is typically required for modern Mopar engines.
- Oil capacity: Approximately 5.9 quarts (about 6 quarts) of oil with filter replacement.
- Change interval: Follow the owner's manual; typically around every 7,500 miles under normal driving, or more often under severe service.
When in doubt, consult the vehicle's manual or the under-hood label. Different trims or climates may have slight variations, and some dealers may specify a particular brand to ensure MS-6395 compliance.
Considerations for climate and driving conditions
In regions with extreme temperatures or demanding driving, ensure you select an oil meeting the required performance standards and consider synthetic oil for better protection and longer drain intervals. Do not substitute oil that does not meet Chrysler's MS-6395 specification.
Practical steps for an oil change
Before performing an oil change, gather the correct oil grade and a new filter, and follow safe vehicle jacking and disposal procedures. The following steps outline a typical oil-change process for a 2012 3.6L engine.
- Warm up the engine briefly, turn off, and remove the oil filler cap.
- Raise and secure the vehicle, then place a drain pan beneath the oil pan.
- Remove the drain plug and allow the used oil to drain completely.
- Replace the oil filter with a new Mopar-approved filter and reinstall the drain plug with a new seal.
- Lower the vehicle, fill with the correct amount of 5W-20 oil, and check the level with the dipstick.
- Dispose of the old oil and filter responsibly.
Properly checking the oil level after a change ensures you reach the correct full mark on the dipstick and avoids overfilling or underfilling.
Where to find the official guidance
The most reliable source is the owner’s manual for your 2012 Chrysler model year, or the label under the hood on your specific vehicle. If you still have questions, a Chrysler dealer or a qualified mechanic can verify the exact spec for your vehicle's VIN and climate.
Summary
For a 2012 Chrysler 3.6L engine, use 5W-20 motor oil that meets API SN or newer and Chrysler MS-6395, with an approximate capacity of 5.9 quarts plus filter. Always confirm the exact specification in your owner’s manual or on the under-hood placard, and follow the recommended oil-change interval for optimal engine protection.
