This comes due to State-run oil companies increasing the quantum of ethanol being blended in petrol from 1.91% to 6.73% as against the target of 10%. TNPDA president K. P Murali told reporters that there have been complaints, especially in the southern districts of dealers selling adulterated petrol. “People who have found water in their fuel tanks are coming to petrol bunks and picking fights with us. The water could have been caused by their tank locks not functioning properly or due to ethanol reacting with atmospheric oxygen to form water. If customers have any doubts regarding the quality of petrol sold, they can check the quality at any point of time in the bunks. If they do so before filling up petrol, it is well and good,” he said.
