OMCs Dismiss Contamination Concerns in E20 Fuel After Extensive Quality Testing
State-owned oil marketing companies (OMCs) have dismissed reports regarding chloride contamination and excess moisture in E20 fuel, stating that thorough testing across the entire supply chain confirms the fuel meets required quality specifications.
What Happened
In a joint announcement, IndianOil, Bharat Petroleum, and Hindustan Petroleum stated that intensive random testing across refineries, procurement points, and retail outlets confirmed chloride levels remain well within prescribed limits. The state refiners also rejected claims of excess moisture in the 20 percent ethanol-blended petrol following water-ingress checks.
This clarification follows earlier concerns raised by the Society of Indian Automobile Manufacturers (SIAM) in a letter to the oil ministry, which suggested vehicular components were facing wear due to chloride presence. However, SIAM subsequently retracted the communication, confirming that E20 is safe and clarifying that the earlier data needed further authentication.
Key Highlights
- Refinery Testing: Out of 100 random petrol samples examined across various refineries, chloride content remained consistently low at or below 1 part per million (ppm).
- Terminal Checks: More than 80 samples of ethanol and E20 fuel tested at company terminals recorded chloride levels under 3 ppm.
- Distillery Oversight: A dedicated task force comprising OMC and Centre for High Technology (CHT) representatives inspected ethanol supplies across 80 distilleries over a 10-day period, finding all samples below 3 ppm.
- Retail Monitoring: Approximately 90,000 retail outlets have implemented mandatory checks on underground storage tanks, inspecting them 8 to 12 times daily with no water ingress detected.
Why This Matters
The findings provide official assurance regarding fuel standards across the supply chain, from production at refineries and distilleries to storage at distribution terminals and retail pumps. The tests confirm that blending levels and storage practices maintain fuel integrity without exceeding chloride limits or allowing moisture ingress.
What to Watch Next
State OMCs are continuing mandatory daily monitoring at around 90,000 petrol stations nationwide, inspecting underground storage tanks up to 12 times a day to ensure ongoing fuel quality and prevent moisture entry.
Frequently Asked Questions
What did the OMCs conclude regarding E20 fuel quality?
The state-owned refiners confirmed that chloride levels across all testing points remain strictly within prescribed limits and that there is no evidence of excess moisture or fuel contamination.
What were the specific chloride levels found during testing?
Testing showed chloride levels at or below 1 ppm in refinery petrol samples, while terminal and distillery ethanol samples recorded chloride levels below 3 ppm.
Why was the issue raised initially?
The auto industry body SIAM had sent a letter to the oil ministry flagging potential component wear from chloride in E20 fuel, but SIAM later withdrew the letter, affirming the safety of the fuel.
