Does 2011 Chevrolet Impala require synthetic oil change?

The 2011 Chevrolet Impala does not specifically require synthetic oil; it is designed to run on conventional oil as well. However, using synthetic oil can provide benefits such as better engine protection and longer intervals between oil changes. It's always best to follow the manufacturer's recommendations in the owner's manual for oil type and change intervals. If you prefer synthetic oil, it is generally acceptable to use it in the Impala.
