Let’s Clear the Air about ethanol and emissions. Did you know that the more ethanol you add to gasoline, the cleaner the fuel? Part of this is due to the fact that undenatured ethanol is so pure, you could drink it. While we don’t recommend it, if you think about it, if something is clean enough to drink, would it not improve the quality of gasoline when blended together?
Consider this. When ethanol is added to gas, it’s replacing the most toxic compounds in gasoline called aromatics. These aromatics such as benzene and toluene are added at the refinery to boost octane. Both are known cancer causing agents and ethanol is a readily available and economic alternative. Since almost all regular gasoline includes 10% ethanol, eight billion gallons of aromatics are removed from gasoline by ethanol each year. This significantly reduces tailpipe emissions and improves air quality. And, as more ethanol is added, such as 15% or 30%, aromatics are reduced even more.
Studies done by North Carolina State University and the University of California Riverside show that ethanol blends can reduce toxic tailpipe emissions by up to 50%. The studies also found that ethanol blends reduce the most harmful emissions associated with heart disease and asthma. In addition, the US Department of Agriculture shows corn ethanol reduces greenhouse gas emissions by 39%. So not only are ethanol blends good for the air and environment, studies are showing that reducing emissions is good for public health!
While E30 (30% ethanol blend) is often considered the sweet spot for the most emission reduction and octane boost for your vehicle, did you know that E30 is a premium fuel that costs less than regular? How’s that for Best Value!
So the next time you choose an ethanol blend, whether E10 or higher, know that you are helping reduce emissions, improving air quality and our public’s health. Do you have question about ethanol blends? We’re happy to answer them, just email firstname.lastname@example.org.
