The type of oil for a Chrysler Sebring V6 sedan depends on the
year of your vehicle. Chrysler's recommendations changed over time. You
must check your owner's manual for the precise specification. The manual will specify the oil type (e.g., 5W-20, 5W-30, etc.) and the API certification (e.g., SN, SM, etc.).
Using the wrong oil can seriously damage your engine. Don't rely on general advice; consult your owner's manual. The information sticker on the inside of the driver's side door jamb may also list some specifications.
