To find the correct amount, consult your owner's manual. This manual will specify the exact capacity for your specific year and model Sebring. This is the most reliable source of information.
If you don't have the owner's manual, you can try searching online for a PDF version using your vehicle's year, make, model, and engine size. Alternatively, you can contact a Chrysler dealership or a reputable auto parts store; they may be able to look up the information based on your VIN.
