The 2001 Chrysler Sebring LXi's recommended oil type depends on the engine it has. There were a few different engines offered that year.
You absolutely must check your owner's manual for the definitive answer. The manual will specify the correct viscosity (like 5W-30 or 10W-40) and the type of oil (conventional, synthetic blend, or full synthetic).
Looking up the specifications online without knowing the exact engine is unreliable and could damage your engine. The owner's manual is the only truly reliable source.
