Yes, using regular fuel in a hybrid car like the Ford Fusion Hybrid or Chevy Volt is possible instead of E85 fuel. Here’s an explanation of the points:

Hybrid Cars' Flexibility: Most hybrid vehicles, including the Ford Fusion Hybrid and Chevy Volt, are designed to run on regular gasoline (typically 87-octane). They do not require E85 fuel to operate.

E85 Fuel: E85 is a blend of 85% ethanol and 15% gasoline. It is only compatible with flex-fuel vehicles (FFVs). Hybrid cars like the Ford Fusion Hybrid and Chevy Volt are not designed to run on E85 unless designated as flex-fuel models.

Regular Gasoline: These hybrids are built to use regular fuel (unleaded gasoline). Their internal combustion engines are calibrated for standard gasoline, making it the appropriate fuel choice.

Fuel Economy: Using E85 in a non-flex-fuel vehicle like the Chevy Volt or Ford Fusion Hybrid can damage the engine and void the warranty. Sticking to regular gasoline ensures optimal performance and fuel economy.

Engine Compatibility: Hybrids are not typically equipped with the necessary engine components to handle the higher ethanol content in E85, which can lead to corrosion or other issues over time.

Electric Component: Both vehicles, being hybrids, have electric components (like batteries) that assist the gasoline engine, so they do not rely solely on fuel combustion for power, which further reduces the need for specialized fuels like E85.

In summary, regular gasoline is safe and recommended for hybrid cars like the Ford Fusion Hybrid and Chevy Volt. E85 is unsuitable for these vehicles unless they are designed to accept it.
