Recently, there has been an increasing debate over the accepted quantity of ethanol in gasoline; trying to balance prices, environmental concerns, as well as efficiency has made this a rather daunting activity. The lawful restriction for gasoline-powered engines is 10 percent; some producers of this product remain in the procedure of getting a waiver to enhance the acceptable total up to 15 percent. This is where the problem between makers of engines and also manufacturers of this renewable resource source is the sharpest.
The arguments of opponents are also convincing. Makers mention that the lower energy content of these energy blends ultimately equates right into more energy usage as well as higher rates for the consumer. The newer flex-fuel motor vehicles, which make use of a mix of 85 percent ethanol and 15 percent gas, actually have a reduced gas mileage compared to their traditional equivalents. A second disagreement is that older engines (those made before 2001) are not accepted for the more recent blends and could possibly experience problems. Finally, there is a continuous discussion as to whether land that can be used for increasing meals crops should, rather, be used to generate crops for energy.
