Meta Description: India's top vlogger Sourav Joshi's Mercedes saw its mileage crash from 17 to 5 kmpl after using E20 petrol, sparking a massive debate on the government's ethanol-blending policy. Read the full story.
India's most prominent daily vlogger, Sourav Joshi, has ignited a firestorm of debate after revealing that his luxury Mercedes-Benz SUV's fuel economy has taken a nosedive, which he squarely blames on the country's ethanol-blended petrol. With a staggering 41 million subscribers, Joshi's viral video diary has brought the simmering public anxiety over E20 fuel into the living rooms of millions, transforming a personal grievance into a national conversation .
In a recent vlog titled 'Race With Brothers. Kon Jeetega ?', Joshi expressed his dismay directly from the driver's seat of his Mercedes-Benz GLC 300 4MATIC, pointing at the dashboard's live mileage indicator. The figures were stark and alarming. He described how his vehicle, which typically delivered an admirable 17 kmpl, has seen its efficiency plummet to 9 kmpl within a mere 48 hours . In a later update, the situation appeared to worsen significantly, with the display showing a staggering low of 5 kmpl . It remains unclear if these figures represent real-time consumption or the overall trip average, but the dramatic drop is undeniable and has resonated deeply with a public grappling with rising fuel costs and vehicle maintenance."
Yesterday I told you that our car's mileage had dropped from 17 straight to 9. And today, do you know how much it has become? It has gone down to 5." —
Sourav Joshi Fuel Fears and the "Scared" Vlogger
The Haldwani-based creator's frustration was palpable as he highlighted the tangible consequences of this mileage crisis. He revealed that a full tank of fuel, which used to promise a driving range of approximately 800 kilometres, now barely projects 480 kilometres . This significant reduction in range is not merely an inconvenience but a financial blow, effectively increasing the cost per kilometre of driving his premium SUV .
Joshi's concerns go beyond mere fuel economy. He expressed a growing fear of visiting petrol pumps, worrying about the potential for long-term mechanical damage to his expensive vehicle. "These days I'm actually scared while filling petrol, wondering if the car might get damaged, because a lot of people's vehicles are getting spoiled due to fuel adulteration," he confessed . This sentiment is a powerful reflection of the anxiety felt by many Indian car owners who fear that the push for ethanol blending might come at the cost of their vehicles' health and reliability . He articulated the logistical nightmare of owning a luxury car in a smaller city, noting that any significant mechanical fault could require his vehicle to be sent to Delhi for repairs, entailing massive logistical challenges and repair costs . His wife, Avantika Bhatt, echoed his sentiment, lamenting, "We spent so much money on this car!" .
Interestingly, Joshi also mentioned his relief at owning an electric version of the Mercedes G-Wagon, which insulates him from the uncertainties of ethanol-blended fuel .

The Official Line vs. Ground Reality
The government's ambitious E20 programme, aimed at reducing crude oil imports, lowering carbon emissions, and boosting the agricultural economy, has been a cornerstone of India's energy policy . The Ministry of Petroleum and Natural Gas has acknowledged that ethanol has a lower calorific value than petrol, which can cause a slight decrease in mileage—estimating a 3-6% reduction for older vehicles not calibrated for the blend .
However, a recent survey by LocalCircles paints a dramatically different picture from the ground. Of over 22,000 responses, a staggering two in three vehicle owners reported a significant reduction in fuel efficiency in 2025, with 11% stating their mileage had dropped by over 20% . This suggests that the official estimates may be significantly underestimating the real-world impact on consumers.
Mercedes-Benz India has attempted to calm the waters, asserting that their vehicles manufactured from 2020 onwards are fully E20-compliant. Managing Director and CEO Santosh Iyer argued that the primary threat is not the ethanol itself but the inconsistency and potential adulteration of fuel at retail outlets. "We have seen increased fuel adulteration happening under the garb of E20," he stated, suggesting that some pumps might be dispensing blends far exceeding the 20% limit . He urged policymakers to offer multiple fuel grades during the transition to allow owners of older vehicles a choice . This official stance, however, does little to assuage the fears of consumers like Joshi who are experiencing problems firsthand and often find themselves in a frustrating he-said-she-said scenario between the government and automakers.

A Nation Divided: The Social Media Firestorm
Unsurprisingly, Joshi's viral complaint has divided public opinion on social media. Many users have rallied behind him, sharing similar experiences and lauding him for using his platform to highlight a critical consumer issue. One user commented, "Good job highlighting the problems with ethanol. I wish the government would listen to you," while another directly challenged the government, tagging Minister Nitin Gadkari and stating, "Here is your 'real-life case.'" . This public sentiment is fueled by a sense of being caught in the middle of a policy shift without adequate support or compensation for the potential downsides .
Conversely, some sceptics questioned the type of fuel Joshi was using, arguing that luxury vehicles like Mercedes-Benz strictly recommend high-octane premium unleaded petrol (95-98 RON), and using regular E20 may not be suitable for its engine mapping . This raises a critical point about consumer responsibility and the lack of clear, accessible information about fuel grades at the pump .

The Broader Context: A Cautionary Tale
Joshi's experience is not an isolated incident. It echoes similar complaints from other luxury car owners, including a Chandigarh-based Ferrari owner who reportedly faced a "refuse to start" issue after filling up with E20, leading to concerns about ethanol's hygroscopic nature and its effect on fuel systems in cars that are not driven daily . These high-profile cases, while representing a fraction of the total vehicle population, serve as powerful symbols of a broader underlying problem.
The debate over E20 petrol underscores a fundamental conflict in India's policy landscape: balancing the nation's macroeconomic energy security goals with the real-world economic burden and technical compatibility concerns of its vast and diverse vehicle population. While the government touts forex savings and support for farmers, critics point out that the mileage losses for consumers could potentially wipe out a significant portion of these savings .

The Road Ahead: A Fight for Transparency and Choice
The Sourav Joshi Mercedes mileage saga is more than just a viral moment; it is a critical litmus test for the government's communication and implementation strategy for a significant national policy. While the long-term benefits of the E20 programme are clear, the government appears to be losing the public relations battle, with many citizens feeling unheard and burdened.
For the government to successfully navigate this transition, several crucial steps are needed. Firstly, there is an urgent need for greater transparency regarding the quality and exact ethanol percentage of fuel being dispensed. Second, the government must facilitate a smoother transition by ensuring a choice of fuel grades is available during the interim period, protecting owners of older vehicles . Finally, a more empathetic and less combative stance towards public criticism would go a long way in building trust. Dismissing legitimate consumer concerns as "misinformation" or a "false narrative," as done by some ministers, only serves to alienate the very people the policy is meant to serve .
Sourav Joshi has become an unlikely spokesperson for millions of frustrated car owners. His story is a powerful reminder that policy success lies not just in achieving macro targets, but in ensuring that its implementation respects and accounts for the lived realities of its citizens. The debate rages on, but Joshi's message is clear: you can't ignore the blinking dashboard light on your national policy when it starts affecting the common man's wallet—or his luxury car's performance.
