Karnataka challenges oil firms over excessive ethanol in petrol samples

The Karnataka government said it stands firmly behind laboratory reports indicating that petrol samples collected across the state contained more than the mandated 20 per cent ethanol content, with some samples registering as high as 31.2 per cent.

State Minister Rizwan Arshad said the government's findings raise serious questions about compliance with fuel blending standards set by authorities. The discrepancies appear to contradict claims made by major oil firms regarding the ethanol content in their fuel supplies to retail outlets across Karnataka.

The issue has emerged as a potential quality control problem, with implications for vehicle performance and emissions standards. Ethanol blending in petrol is a regulated practice intended to reduce fossil fuel consumption and promote cleaner fuel alternatives, but must adhere to prescribed limits to avoid engine damage and operational issues.

The government's assertion of higher ethanol concentrations than permitted suggests either inconsistent blending practices among fuel suppliers or gaps in monitoring mechanisms. Officials indicated they would pursue the matter further with oil companies and regulatory bodies to ensure compliance with fuel quality standards.

The dispute underscores ongoing concerns about fuel quality oversight in India's petroleum retail sector and the need for rigorous testing protocols to protect consumer interests and vehicle performance standards.
