Re: How to Blend Your Own Fuel, and Why You Should

Due to ethanol's lower vapor pressure, engine ignition is more difficult in colder weather for vehicles running on fuels with high ethanol content. During winter months, gasoline is added to E85 (85% ethanol and 15% gasoline blend) to make E70 (70% ethanol and 30% gasoline), which has a vapor pressure that improves starting in cold weather. Although current practice is to "blend-down" E85, the cold-start issue is a technologically solvable engineering problem for vehicle manufacturers.
