Re: 100% Gasoline...definately better
You are fortunate if you live in a area where you can purchase ethanol-free gasoline. In large cities and heavy industrial areas where air pollution is an issue, all gasoline must contain at least 10% ethanol. These geographical areas are referred to as "EPA Non-Attainment Areas" because the area has not met the EPA standards for reduction in volatile organic compounds (VOC) and nitrous oxide (NOx) pollutants. I live in the Houston, TX metro area, ethanol-free gas is not available for approximately 100-mile radius.
PURE GAS is a cell phone app that locates and maps the closest service stations providing ethanol-free gas. It provides address and distance to both branded and unbranded stations. PURE GAS is a great tool to avoid ethanol.
If I had a choice, I would never buy ethanol gasoline.
