What are they going to put in the gasoline to keep it from knocking in cars? They use to use lead and it has health issues and then they used MTBE and it caused cancer, also health problems. Now ethanol is used to solve this. If they try to get rid of ethanol then what?


Lead and various petroleum products have provided octane to gasoline for over 100 years, but evolving health and environmental concerns have led policymakers to reconsider the widespread use of many of these compounds. As the United States looks to reduce the greenhouse gas intensity of the transportation sector, increasing the octane value of gasoline is a promising avenue, as it would enable more fuel-efficient engines. But the health and environmental impacts of the octane sources that are used must be considered as well. By adding ethanol to finished gasoline, called “splash blending,” octane ratings can be increased while simultaneously lowering toxic octane sources.

A national transition to an optimized mid-level ethanol blend, between E25 (25 percent ethanol, 75 percent gasoline) and E40 (40 percent ethanol), would lower consumer fuel costs and standardize the fuel supply. The Department of Energy recognizes that increasing the ethanol content of gasoline is a potential pathway to increasing the octane rating of the gasoline supply. A mid-level ethanol blend would enable the design of highly fuel-efficient engines that would significantly reduce petroleum consumption, reduce lifecycle greenhouse gas emissions, and help meet higher fuel economy standards. As of now, the Department of Energy and the EPA have approved the use of E15 for make and model year 2001 and newer vehicles, which account for 80 percent of the vehicles on the road today.

Automotive manufacturers are examining clean octane sources as a way to meet efficiency and greenhouse gas regulations. It is here that the greatest benefit to health, the environment and vehicle efficiency can be realized in the near-term.
