While it can improve engine performance and environmental impact when used in small amounts, higher concentrations like E85 can cause engine issues, especially in older vehicles. Most modern cars are designed to run on a 10% ethanol blend, but the overall environmental and economic impacts of ethanol fuel remain contentious.
