Megha Prasad Asked Gadkari About Her Honda City Mileage Drop. His Answer Went Viral.

In a televised interview that went viral in July 2026, News18 anchor Megha Prasad confronted Union Minister Nitin Gadkari with her own vehicle data: her Honda City’s mileage had dropped from 11–12 km/l to 7 km/l on E20 — a roughly 40% reduction. She asked him directly what vehicle owners are supposed to do. Gadkari’s response — that tank-fill mileage checks are “unreliable” and should be verified at authorised dealers “using machines” — itself became the story, with critics calling it a dismissal of the lived experience of millions.

The interview

The exchange occurred during a television interview on News18, one of India’s largest news channels. Megha Prasad, a senior news anchor known for direct questioning, was interviewing Gadkari on the E20 controversy, which was at its peak in July 2026 following the Sourav Joshi retraction, the Manish Kashyap FIR, and the AG’s “experiment” remark in the Supreme Court.

Rather than relying on third-party anecdotes, Prasad made the question personal. She told Gadkari that her own Honda City — a popular sedan made by Honda Cars India — had experienced a mileage drop from 11–12 km/l to 7 km/l after switching to E20. That is a reduction of approximately 36–42%, depending on the baseline.

Her question was direct: What are vehicle owners supposed to do?

Gadkari’s response

Gadkari’s response addressed the methodology, not the experience. He made several points:

1. Tank-fill mileage calculations are “unreliable”: Gadkari said that the common practice of calculating mileage by tracking fuel fills and odometer readings is not scientifically accurate. Variables like driving conditions, traffic, air conditioning usage, tyre pressure, and driving style introduce too much variation for meaningful conclusions.
2. Mileage should be checked “at authorised dealers using machines”: He suggested that owners who believe their mileage has dropped should take their vehicles to authorised service centres, where calibrated equipment can measure fuel consumption under controlled conditions.
3. Warranty complaints should go through dealers and consumer court: If the vehicle is under warranty and the mileage drop is confirmed by an authorised dealer, the owner should file a complaint with the dealer. If the dealer does not resolve it, the owner can approach a consumer court.

Why the response went viral

Gadkari’s response was technically defensible but practically tone-deaf, and the gap between the two is what made it viral. Here is why:

The methodology argument is correct but irrelevant to the point

It is true that tank-fill mileage calculations have margins of error. Driving patterns, traffic, and environmental conditions affect real-world mileage. No one disputes this. But when millions of owners report the same directional change — mileage going down, not up, and going down after the switch to E20 — the aggregate signal is meaningful even if individual data points are noisy.

Dismissing individual measurements as “unreliable” when the pattern is consistent across millions of owners is like dismissing a thermometer reading because it has a ±0.5°C margin of error when every thermometer in the city shows the temperature rising. The precision of each reading is less important than the direction of the change.

The dealer-verification suggestion is impractical at scale

India has approximately 300 million petrol vehicles. There are roughly 4,500 authorised service centres for all brands combined. Even if each centre handled 10 mileage-verification tests per day (an optimistic assumption, given that this is not their primary function), it would take over 18 years to test every vehicle once:

300,000,000 vehicles ÷ (4,500 centres × 10 tests/day × 365 days) = 18.3 years

The suggestion is operationally impossible. It would require millions of owners to take time off work, drive to a dealer (using the very fuel that is costing them more), wait for a test, and then pursue a complaint process that most have no experience navigating. For the vast majority of vehicle owners, this is not a solution — it is a bureaucratic obstacle course designed to make the complaint go away.

The consumer-court suggestion shifts burden to citizens

Suggesting that affected owners pursue consumer court is legally sound but practically disproportionate. Filing a consumer complaint requires:

• Gathering evidence (mileage logs, service records, mechanic statements)
• Drafting the complaint (or hiring a lawyer)
• Paying court fees
• Attending hearings over months or years
• Potentially facing appeals by the respondent

For a mileage loss that costs the average owner ₹500–₹2,000 per month, the time and expense of a consumer court case may exceed the value of the claim. This is rational for each individual owner, but it means the policy imposes a cost that is individually too small to litigate but collectively massive — a classic collective-action problem.

The government created the problem (by mandating E20 with no alternative). It then told 300 million individual owners to each solve the problem separately, at their own expense, through the courts. This is not accountability — it is diffusion of responsibility.

What the Honda City data tells us

Prasad reported a drop from 11–12 km/l to 7 km/l. Let us examine whether this is consistent with what E20 does:

• Energy-content loss: E20 contains approximately 6.5% less energy per litre than E0. This alone would account for a mileage drop from 12 km/l to approximately 11.2 km/l — a modest reduction, not a crash to 7 km/l.
• ECU calibration: If the Honda City’s engine control unit (ECU) is calibrated for E10 or E0, running E20 may cause the engine to run slightly lean (insufficient fuel for the air-fuel mixture), which the ECU may overcompensate for by enriching the mixture, leading to additional fuel consumption beyond the energy-content difference.
• Other factors: City driving conditions, air conditioning in Indian summers, vehicle age, and maintenance can compound the effect. The Honda City reported was likely a pre-2023 model originally tuned for lower ethanol blends.
• Compounding factors: In real-world conditions, multiple factors stack. The 6.5% energy loss is the floor, not the ceiling. Owner surveys consistently show losses of 10–20%, and some vehicles — particularly in city-driving conditions — report losses exceeding 25%.

A 40% drop, as Prasad reported, is at the extreme end but not physically impossible for a vehicle whose ECU calibration, driving conditions, and vehicle age all compound the base energy-content loss. Whether her specific number is precisely accurate is less important than the direction: she experienced a significant, noticeable mileage drop after E20, and the minister told her it did not count because she measured it the way every vehicle owner in India measures it.

The bigger issue: who owns the data?

Gadkari’s suggestion that mileage can “only be checked at authorised dealers using machines” raises a fundamental question: who owns the data on E20’s impact?

If only authorised dealers can produce valid mileage data, then:

• The data is controlled by companies (OEMs and their dealer networks) that have a commercial interest in certifying their vehicles as E20-compatible.
• No independent, citizen-accessible method of measurement is considered valid.
• The government can dismiss any and all owner-reported data as “unreliable” because it was not produced by an approved institution.

This is a data-sovereignty issue. In a system where the only accepted evidence comes from parties aligned with the policy, criticism can always be dismissed on procedural grounds. The government does not need to address the substance of the complaint if it can disqualify the evidence.

What Prasad did differently

Prasad’s intervention was significant because of who she is and how she framed the question:

• She is a mainstream media anchor, not an opposition politician, influencer, or activist. Her credibility is professional, not partisan.
• She used her own vehicle data, not someone else’s anecdote. This personalised the question and made it harder to dismiss as secondhand information.
• She asked “what should owners do?” — a practical question that demanded a practical answer. Gadkari’s response (go to a dealer, file a consumer case) exposed the gap between the policy and any actionable remedy.
