Ethanol, a renewable fuel source derived from plant material such as corn, has gained popularity as an alternative to gasoline due to its potential to reduce greenhouse gas emissions. However, despite its numerous advantages, using ethanol-blended fuel in gas engines can have negative effects on engine performance and durability. This article will delve into the detrimental consequences of ethanol on gas engines and various components, shedding light on the challenges faced by vehicle owners and manufacturers alike. Decreased Fuel Efficiency The presence of ethanol in gasoline can significantly impact fuel economy. Ethanol has a lower energy density compared to traditional gasoline, resulting in decreased mileage per gallon for vehicles operating on ethanol blends. This reduced fuel efficiency can be attributed to ethanol's lower energy content, requiring engines to burn a larger volume of fuel to reach the same power output as conventional gasoline. As a result, d ... read more
