Only 4 Cases of Fuel Contamination Found in Daily Testing of 2,000 Samples, Says Oil Minister Hardeep Puri

New Delhi — Union Minister for Petroleum and Natural Gas Hardeep Singh Puri has moved to calm public anxiety over India's E20 ethanol-blended petrol rollout, revealing that intensive nationwide testing has turned up just four confirmed cases of fuel contamination out of thousands of samples checked daily.

What Puri Said

Speaking on Friday at the 7th CII International Energy Conference & Exhibition, Puri said oil marketing companies have been collecting roughly 2,000 fuel samples every day from petrol stations across the country using dedicated testing teams. Across India's entire retail network of 1.07 lakh (107,000) outlets — serving an estimated six to seven crore customers daily — only four contamination cases have surfaced so far.

The minister pushed back against what he described as selective framing of the testing data, suggesting that some parties were presenting the findings "out of context" to stoke concern over the ethanol-blending programme. He noted that heightened testing had actually begun about two weeks before an industry body raised concerns in a letter dated July 28, indicating the government was already ahead of the controversy rather than reacting to it.

Puri also argued that isolated contamination incidents are not unique to E20 fuel, noting that such issues "can happen in anything," and should not be used to undermine India's broader biofuel blending strategy — a signal that the government intends to hold firm on the ethanol rollout despite opposition criticism.

Network Resilience and Expansion

Beyond the contamination numbers, Puri used the platform to highlight the broader strength of India's fuel retail infrastructure. He said the network has nearly doubled in size over the past decade, growing from around 52,000 outlets in 2014 to approximately 107,000 today. Despite recent global supply-chain pressures, he said, not a single outlet in the country has run out of stock.

He attributed this resilience to a combination of factors: diversified crude oil sourcing, strategic reserves that can cover roughly 74 days of national demand, and steady investment in distribution infrastructure. Puri also pointed to India's growing stature in the global energy landscape, noting the country is now the third-largest energy consumer and fourth-largest refiner in the world, with fuel demand growing at nearly three times the global average.

LPG Supply and Energy Security

On cooking gas, Puri addressed — and dismissed — recent speculation about a possible levy on LPG, calling such reports baseless and unfair to circulate without confirmation from the ministry.

He also detailed how India managed a brief period of concern over LPG supplies from Gulf nations near the Strait of Hormuz, saying domestic production was ramped up from about 34,000 to 55,000 metric tonnes a day, partly by reconfiguring refinery output. The United States now supplies roughly 67% of India's LPG imports, he said, a shift that has meaningfully reduced the country's dependence on Gulf supply routes.

Mumbai High Revival and Fuel Pricing

Puri additionally announced government backing for a collaboration between ONGC, Brazil's Petrobras, and BP to revive production at the Mumbai High offshore oil fields, which were first discovered in 1974. The government will support drilling costs for the project by up to 50%, capped at roughly ₹650 crore per well.

On fuel prices, the minister acknowledged that global crude volatility has pushed petrol and diesel prices up marginally in recent years, but pointed to excise duty cuts implemented in November 2021, May 2022, and March as measures that have helped cushion the impact on Indian consumers.

Why It Matters

The remarks come at a sensitive moment for India's ethanol-blending programme, which has faced growing scrutiny from opposition parties and sections of the public since the rollout of E20 fuel nationwide. By putting a hard number on the contamination rate — four cases against tens of thousands of daily samples — Puri is attempting to reframe the narrative around E20 from one of safety risk to one of statistical reassurance, while simultaneously showcasing the government's broader energy security gains on refining capacity, LPG diversification, and strategic reserves.
