You guys like getting screwed by the ethanol farce. Try this one on:
Straight from the US dept. of Energy site Q&A regarding new vehicle testing:
Do EPA fuel economy estimates account for the use of ethanol blends that are common today?
No. The EPA fuel economy tests use 100 percent gasoline, and no adjustments are made to account for ethanol. Most conventional vehicles using E10 (10 percent ethanol) will experience a 3 to 4 percent reduction in fuel economy.
