As the devastating floods led to several infrastructure bottlenecks across Chennai and its suburbs over the last week, retail fuel outlets reportedly "ran dry" following lack of supply.
"Customers are requested not to panic. There is no fuel shortage in the city. Due to heavy water-logging many petrol pumps are not being operated due to safety and security reasons, as fueling is an electrical operation", the company said in a statement.
Besides, availability of service staff like tank truck drivers and pump attendants has become a "big challenge" in the current situation.
All efforts were being made to effectively dispense fuel wherever feasible, Indian Oil said.
