As automakers continue to reduce the number of flex fuel vehicles they produce, one model still stands out: the Buick Envista.

The compact crossover is one of the few modern vehicles available as a flex fuel vehicle (FFV), giving drivers the ability to fuel with gasoline, E85, or any blend of the two.

For drivers interested in E85, the Buick Envista offers something that’s becoming increasingly rare.

Like all flex fuel vehicles, it’s designed to automatically adjust to the fuel in the tank. Drivers can fill up with gasoline, E85, or switch between the two at any time—no modifications required.

That flexibility gives drivers more choice at the pump while making it easy to take advantage of E85 when it’s available.

Why choose E85?

Many flex fuel vehicle owners choose E85 because it often costs substantially less than gasoline while offering an octane rating of 100+.

Made with renewable ethanol, E85 provides another fueling option for drivers looking to reduce fuel costs without giving up performance.

Fueling with E85 in California

With more than 600 E85 stations across California, it’s easier than ever for Buick Envista owners to fuel with E85.

The Pearson Fuels App helps drivers find nearby stations, compare current fuel prices, and navigate directly to participating locations.

As one of the few modern flex fuel vehicles on the market, the Buick Envista shows that drivers still have options when choosing a vehicle that can take advantage of E85.
