1. Understanding Ethanol and Its Impact on Your Vehicle
Ethanol, a type of alcohol derived from corn and other plant materials, is commonly blended with gasoline to create what is known as “gasohol.” While the addition of ethanol is intended to boost octane levels and reduce emissions, it can have several adverse effects on your vehicle, especially older models.
1.1 What is Ethanol-Blended Gasoline?
Ethanol-blended gasoline typically contains up to 10% ethanol (E10), although some blends can have higher concentrations such as E15 (15% ethanol) or E85 (51-83% ethanol). The U.S. Environmental Protection Agency (EPA) mandates the use of ethanol in gasoline as part of the Renewable Fuel Standard (RFS) program, aimed at reducing greenhouse gas emissions and promoting the use of renewable energy sources.
1.2 The Downsides of Ethanol
Ethanol is hygroscopic, meaning it attracts and absorbs water from the atmosphere. This water absorption can lead to several problems:
- Corrosion: Water and ethanol can corrode metal components in your fuel system, including fuel lines, carburetors, and fuel pumps.
- Material Degradation: Ethanol can degrade rubber and plastic parts in older vehicles, causing them to crack and leak.
- Phase Separation: If too much water is absorbed, the ethanol and gasoline can separate into two distinct layers, with the ethanol-water mixture settling at the bottom of the fuel tank. This phase separation can lead to engine misfires and poor performance.
- Reduced Fuel Economy: Ethanol has a lower energy content than gasoline, so ethanol-blended fuels typically result in lower fuel economy. According to the U.S. Department of Energy, E10 can reduce fuel economy by about 3-4%.
1.3 Potential Benefits of Ethanol
Despite the downsides, ethanol does offer some benefits:
- Higher Octane: Ethanol increases the octane rating of gasoline, which can improve engine performance, especially in vehicles designed to run on premium fuel.
- Reduced Emissions: Ethanol can reduce emissions of certain pollutants, such as carbon monoxide and particulate matter.
- Renewable Resource: Ethanol is derived from renewable resources, making it a more sustainable alternative to fossil fuels.
2. Why Non-Ethanol Gas Might Be a Better Choice
For many car owners, especially those with classic or older vehicles, non-ethanol gas can be a superior choice. Here’s why:
2.1 Preserving Older Vehicles
Classic and vintage cars were not designed to run on ethanol-blended fuels. The ethanol can damage the fuel system components, leading to costly repairs. Using non-ethanol gas helps preserve these vehicles by preventing corrosion and material degradation.
According to the Classic Car Club of America, using non-ethanol fuel is one of the best ways to maintain the integrity of classic car fuel systems.
