★ Top Answer
The 2009 Chevy Impala runs on regular unleaded gasoline with an octane rating of 87 or above. Never use E85 or diesel fuel in your Impala because it can cause serious damage to the fuel system and engine. It’s best to choose the highest octane level available when refueling to ensure cleaner and more efficient burning of fuel. This will prevent carbon buildup in the engine over time. Look for fuels labeled as top tier, as they contain detergents that can aid in breaking down engine sludge and buildup.

Whether your 2009 Chevy Impala is equipped for flex fuel determines the type of fuel you should use. If your car lacks the flex fuel badge on the trunk, stick to using 85 octane regular unleaded gasoline or higher. However, if your 2009 Impala has the flex fuel badge, you can opt for E85 fuel as well as 85 octane regular unleaded or higher gasoline.
