Ethanol, often called “biofuel,” has been used in vehicles for over a century, yet its role in modern vehicles is still a topic of debate. Several key concerns have contributed to ethanol’s complex reputation. *
- Performance issues with older vehicles
- Higher costs compared to regular gasoline
- Potential environmental harm
- Emissions impact
- History of ethanol use
- Environmental benefits
- Engine performance concerns
- Fuel costs and availability
Despite the controversies, most modern vehicles run on 90% ethanol and 10% gasoline without issue, making fuel with ethanol an appealing alternative.
| Key points | Benefits | Concerns |
|---|---|---|
| Prevents engine knocking | Burns cleaner and produces fewer emissions | Higher cost, potential engine damage |
| Reduces greenhouse gas emissions | Renewable source of energy | Dependence on corn and other non-renewable sources |
“Ethanol is a cheap energy source, but it is also a source of food, and the food prices can be very high.” – Dr. Jane Smith
Using E85, a 90% ethanol and 10% gasoline blend, requires specific vehicles and can result in additional costs and potential damage to older engines.

The decline in certified flex-fuel vehicles is also a concern for the future of ethanol in vehicles. As few as 10 new models are expected to be certified by 2025. The Buick Encore GX is one of the only vehicles to be certified as a flex-fuel-capable model.
As people begin to look for alternative energy sources and new ways to address environmental concerns, the role of ethanol in modern vehicles will likely continue to evolve. With the complexities of ethanol in mind, it is crucial to consider its use and potential drawbacks before making a decision on your next vehicle or refueling choice.
While ethanol is not the perfect solution, it can still be a valuable addition to your fuel mix, especially when used in the right circumstances.
