Are 2007 Suburbans Flex Fuel? Exploring Fuel Options In The 2007 Suburban

Is a Suburban a flex fuel vehicle? Yes, a Suburban is indeed a flex fuel vehicle, meaning it can use a wide range of fuel options. As F_O_R mentioned, you can use regular 87 octane to 93 octane gasoline, whether it contains ethanol or not. Additionally, your Suburban can run on ethanol-blended fuels with ethanol content ranging from none (pure gasoline) up to E-10 and all the way to E-85. It’s worth noting that while E-85 is a cost-effective alternative to regular gasoline, using it may result in slightly reduced fuel mileage.

The 2007 Chevrolet Suburban is equipped with a significant enhancement that distinguishes it from its predecessors: the Active Fuel Management (AFM) System. This innovative technology was incorporated to address the well-known issue of the Suburban’s high fuel consumption, with the primary aim of enhancing the vehicle’s fuel efficiency.
