Does old gas have ethanol?
According to the U.S. Energy Information Administration, most gasoline sold in the U.S. is “E10” gas made of 90 percent petroleum-based gas and 10 percent ethanol (ethyl alcohol). Ethanol-blended gas usually has a shelf life of up to three months because of the high speed at which ethanol oxidizes.
Do I get gas with ethanol or no ethanol?
While not as popular as the ethanol blends, pure gas may be preferable for older car engines, as well as boats, lawn mowers or other tools. Ethanol-free gas also gets better fuel economy. However, most drivers use the E10 or E15 blends, with 10-15% ethanol. That ethanol content only reduces gas mileage by around 5%.
What is the purpose of ethanol-free gas?
