E20 petrol may harm BS-III vehicle rubber parts, says Nitin Gadkari

Road transport minister Nitin Gadkari informed Rajya Sabha Wednesday BS-III vehicles, manufactured between 2005 and 2016, may require replacement of some rubber parts and gaskets when run on E20 petrol, while adding studies have found no major impact of the blended fuel on overall vehicle performance.

In a reply to a question, Gadkari said studies conducted by IOCL, Indian Institute of Petroleum, Society of Indian Automobile Manufacturers and Automotive Research Association of India (ARAI) found BS-VI vehicles continued to meet emission norms when tested with E20 fuel.

Gadkari added studies have not shown any need to modify the car and two-wheeler engines. “These studies confirmed that even legacy vehicles did not exhibit any significant variations in performance, nor do they show abnormal wear-and-tear when operated with E20 fuel.

No issues were reported in parameters such as drivability, startability, metal compatibility, and plastic compatibility,” he said.
