🚗There is no clear evidence that ethanol prevents carbon buildup.
💧Ethanol is hydrophilic and can separate from gasoline when water is added.
⛽Ethanol can improve fuel efficiency but may reduce the octane level of gasoline.
🔬Further testing is needed to evaluate the effects of ethanol on rubber and plastic components.
