The recommended oil type for a 2008 Chrysler Sebring depends on the engine it has. There were several engine options available that year. To know for sure,
you need to check your owner's manual. It will specify the exact type and viscosity (like 5W-20 or 5W-30) of oil recommended by Chrysler for your specific Sebring's engine.
However, generally, Chrysler vehicles from that era often used 5W-20 or 5W-30 conventional or synthetic oil. Again, refer to your owner's manual for the correct oil type and viscosity. Using the wrong oil can damage your engine.
