Amid concerns over government's 20% ethanol-blended petrol (E20) programme, Union Minister of Road Transport Nitin Gadkari said, "This is completely false. We've done trials on old cars." "There are some people in...petroleum lobby who're spreading this...we've verified everything on technical grounds," Gadkari added. "In Brazil...they do 27% blending but there have been no complaints," he stated.
