Detroit motorists had the opportunity this week to get bargain-priced 10 percent ethanol fuel pumped by some top racers at a Marathon Station in Taylor, Mich.

The pump promotion, sponsored by the Ethanol Promotion and Information Council, was in honor of the American Le Mans Series Detroit Sports Car Challenge on September 1 and the IndyCar Series Detroit Belle Isle Grand Prix on September 2. ALM drivers Peter Dumbreck and Dirk Mueller Peterson of Motorsports/White Lightening Racing and IRL Team Ethanol car driver Ryan Hunter-Reay of Rahal Letterman Racing did the pumping. The price for an hour and a half on Wednesday was a cool $2.45 per gallon, the time allotted for the Detroit Sports Car Challenge presented by Bosch.
