That the 2007 IndyCar Series will be run using 100 percent ethanol is not news, so we won't repeat what we've told you before (see the links below if you missed things). What we will bring up here, late on a Friday, is that tomorrow is finally the day that the 3.5-liter Honda Indy V-8 engine start using pure ethanol in competition.

Wait, it's ovals, right? Anyway, the IRL is using an E10 blend of gasoline and ethanol this season and will start using E100 for all races in 2007.

The league's director of engineering, Jeff Horton, said, "We've had zero problems since our first test at Phoenix." Tests since then have included six IRL races. A typical IRL race uses about 6,000 gallons of fuel and the Indianapolis 500 burned 30,0
