Generally, Dodge Calibers used conventional oil, but some models and years may have specified synthetic blend or full synthetic oil, especially under more demanding conditions or for extended drain intervals. The owner's manual will clearly state the recommended oil viscosity (e.g., 5W-20, 5W-30, 10W-30) and the oil type (conventional, synthetic blend, or full synthetic). Ignoring these recommendations could void your warranty and damage your engine.
