Petrol Punch: Karnataka Slams OMCs Over High Ethanol Levels
Karnataka government challenges OMCs after tests show ethanol levels up to 31.2%, far exceeding the 20% mandate.
The Karnataka government has entered a heated confrontation with Oil Marketing Companies (OMCs) over the quality and composition of ethanol blended petrol being sold across the state. In a formal rebuttal issued on Monday, November 9, 2026, the state administration, led by Chief Minister DK Shivakumar, challenged the claims of fuel giants, accusing them of hiding behind technicalities to avoid transparency.
The Shocking Findings: 31.2% Ethanol?
The dispute ignited after the state’s Department of Food, Civil Supplies, Consumer Affairs, and Legal Metrology conducted an extensive quality check. According to Minister Rizwan Arshad, the government tested 63 distinct petrol samples collected from seven different districts. These included:
- Bengaluru
- Kolar
- Chikkaballapura
- Bengaluru Rural
- Ramanagara
- Mangaluru
- Tumakuru
The results were startling. While the mandated limit for ethanol blending is 20% (E20), internal findings revealed that some samples contained ethanol levels as high as 31.2%. This significant deviation has raised alarms regarding the impact on vehicle engines and consumer rights.
OMCs Fight Back: 'Procedural Violations'
The three major fuel providers—Indian Oil Corporation Limited (IOCL), Bharat Petroleum Corporation Limited (BPCL), and Hindustan Petroleum Corporation Limited (HPCL)—issued a joint statement denying any wrongdoing. The OMCs argue that the fuel they supply fully complies with the Bureau of Indian Standards (BIS) specification IS 17021.
Rather than addressing the percentage levels, the companies attacked the government's methodology. They claim that the state's testing procedures violated the statutory guidelines set under the Marketing Discipline Guidelines (MDG) 2024 and the Motor Spirit and High Speed Diesel (Regulation of Supply, Distribution and Prevention of Malpractices) Order, 2005.
Conflict of Interest and the Demand for Choice
The Karnataka government has pointed out a glaring flaw in the current system: the OMCs are responsible for testing their own products for quality compliance. State officials have described this as a perceived conflict of interest, questioning how companies can be the sole arbiters of their own quality standards.
To protect consumers, Minister Arshad has proposed a more flexible fuel ecosystem. The state is advocating for a system where motorists can choose the specific blend that suits their vehicle's requirements, such as:
- Pure Petrol
- E10 (10% Ethanol)
- E20 (20% Ethanol)
- E30 (30% Ethanol)
The Federal Stance
This state-level battle persists despite assurances from the central government. The Union Ministry of Petroleum and Natural Gas, along with Union Minister of State Suresh Gopi, have previously maintained that fuel samples across the country remain in strict conformity with official quality standards.
To break the deadlock, the Karnataka government has announced plans to convene a high-level meeting with the OMCs to resolve the discrepancies and ensure that the interests of the common citizen are not compromised.
