what cars take e85 gasoline

[MorganRose]

Cars that can use E85 gasoline are specifically designed flex-fuel vehicles (FFVs). These are typically American-made sedans, trucks, and SUVs from General Motors (Chevrolet, GMC), Ford, and Stellantis (Dodge, Chrysler, Jeep). You can identify an FFV by checking for a yellow gas cap, badging that says "Flex-Fuel," "E85," or "FFV," or by consulting your owner's manual. The most definitive method is to search for your Vehicle Identification Number (VIN) on the U.S. Department of Energy's Alternative Fuels Data Center website.

E85, a blend of 85% ethanol and 15% gasoline, requires specialized engine and fuel system components resistant to ethanol's corrosive properties. While E85 is often cheaper per gallon, its energy content is lower, leading to a 15-30% reduction in miles per gallon (MPG) compared to pure gasoline. This means the cost savings only materialize if the price of E85 is significantly lower than regular unleaded in your area.

Vehicle Manufacturer	Example FFV Models (Past & Present)	Approximate Horsepower on E85 vs. Gasoline	Typical MPG Reduction on E85
Ford	Ford F-150 (select models), Ford Explorer, Taurus, Police Interceptor	Slight increase (3-5%) due to higher octane	20-25%
Chevrolet	Chevrolet Silverado, Impala, Tahoe, Suburban	Slight increase (3-5%) due to higher octane	20-28%
Dodge/Ram	Dodge Charger/Challenger (select), Ram 1500, Durango	Slight increase (3-5%) due to higher octane	15-25%
GMC	GMC Sierra 1500, Yukon	Slight increase (3-5%) due to higher octane	22-27%
Jeep	Jeep Grand Cherokee (select models)	Slight increase (3-5%) due to higher octane	20-25%

Before switching to E85, it's a practical calculation. If E85 is 20% cheaper than gasoline but your fuel economy drops by 25%, you'll end up spending more. FFVs offer fuel source flexibility, but E85 is best suited for drivers with easy access to stations and who prioritize supporting domestic, renewable fuel over maximum fuel economy.

Look for the yellow gas cap. That’s the easiest giveaway on a lot of American trucks and SUVs. My old Silverado had one, and I ran E85 for years. You’ll notice you have to fill up more often—the mileage definitely takes a hit. For me, it only made sense when the price difference was huge. Just check the cap or the inside of your fuel door for an E85 sticker. Don't just guess and put it in a regular car; you'll cause damage.

The key is the vehicle's engine control unit (ECU). Flex-fuel vehicles are equipped with a sensor that analyzes the fuel blend and directs the ECU to adjust ignition timing and fuel injection accordingly. This is necessary because ethanol has a different stoichiometric air-fuel ratio than gasoline. Converting a standard gasoline engine to run safely on E85 is complex and costly, requiring changes to the fuel lines, injectors, and ECU programming. It is not simply a matter of filling the tank.

From an economic standpoint, E85 compatibility is common in vehicles built for fleet use and in regions with strong corn ethanol production. Full-size sedans like the Chevrolet Impala and police vehicles were often FFVs to reduce operating costs for large fleets. For an individual, the math is straightforward: calculate your cost per mile. Divide the fuel price by your MPG. If the cost per mile for E85 is lower, it's a saving. However, the lower energy density of ethanol almost always guarantees fewer miles per tank, a trade-off for potential per-mile savings.

I focus on the environmental angle. E85 is popular among drivers wanting to reduce their reliance on fossil fuels, as ethanol is a renewable biofuel. However, the "green" benefit is debated, considering the energy used in farming and distillation. The performance community also appreciates E85 for its high octane rating (typically over 100), which allows for more aggressive engine tuning in high-performance applications without causing engine knock. So, the cars that use it range from work trucks to modified sports cars, all for different reasons.
