Petrol and E85 (bioethanol) maintenance
For Chrysler petrol engines, routine oil and filter changes are the foundation of a reliable service plan, with intervals typically falling in the 5000 to 20000 km range or 3 to 12 months depending on engine and usage. If your car is E85-capable, fuel quality and longer storage periods can affect drivability, so keep up with filters and address hesitation or hard starting promptly. On V6 and V8 engines, pay attention to cooling system condition and belt/auxiliary drive checks as part of regular servicing. Where fitted, spark plugs and ignition components are also key items to inspect on schedule to prevent misfires and catalytic converter damage.
